1src Forums - EB40 Battery Mod

11-18-2005, 07:01 PM

I took the liberty once again to try and find a battery mod that worked with my UX and after figuring out that having an external TH55 battery by itself was dumb, I decided to mod my broken EB40. I took out the chip and battery out of the EB40 and placed my TH55 battery and an extra UX50 battery in the EB40 then ran wires from the EB40 to my UX to connect to the battery port. Since I took out the original wiring in the EB40, this left me with no way to charge. I decided to use my earlier USB mod as my way of charging my device. The downside is that I have to keep my case home now but I'm going to try this for sometime and see how it goes. Both the UX and TH batteries are both 5.2V according to LaptopForLess.com.

Jamerican, i wish i had a broken EB 40 to screw around with ;) Also, Thats your UX50? I know your wifi wasnt working, but did you just change the front display peices to the UX40 peice so it would hde the wifi LED?

yep :). Finally someone notices. Did that intentionally. So that I wouldn't have to mention WiFi disability. Also, my UX40's black border is shinner and much more well kept than my UX50s.

It looks hot :D I very much want a UX40 shell for my UX50, i like the greys and violets... But, i degress. I like the mod :D I am thinking of doing something similar, my UX charges by USB, so i am trying to build a USB battery pack. What is the minimum voltage that a UX will register as charging? Right now im using 2 2000MAh 1.2V cells in tandem. I take it the UX wont say that its charging, but will indeed have a longer battery life? The stpuid project boxes i have are all lame.

JAmerican

11-18-2005, 08:09 PM

Not sure how much the UX will register per say but the external packs that charge work like wall plugs. They just keep your unit at 100%. The EB40 didn't do this. It gave you power than once your EB ran out, you were left with an unfilled battery in your device. I still want to add another battery. I want to find a way to do so. But so far its working well. Its still charging though. I had my TH55 and UX50 battery lying around so its been some time since they had a full charge. Also, one more thing, I can't press the reset button. I have to take the UX off to do so. So, I just use Crash Pro to reset my device automatically on crash.

Why not get another TH55 battery? Two TH55 and one UX. More power than the EB40, I think...

I only had one TH55 battery. I also am thinking of moding my UX's prongs so that the inner prongs are for the battery connection. I currently have only two batteries being used. I hope to make it three in all. By disconnecting the two middle prongs in the UX from the main connection, I can connect the internal battery to it and lead it to the battery connector on the motherboard. Then make the prongs in the EB40 from the chipset send the power from the batteries in the EB40. :) I will mod the connectors of the UX from another device first then move it to my UX50. I have like 3 UXs so I can make mods to those devices for my current device :)

I just got 4AA 2500 MAH batteries. So is that the same voltage as a EB40? Or more? :D

dragonsgames

11-19-2005, 01:27 PM

2500 MAH may be too much. When I plug it into my Clie, it starts making a clicking sound. Like something is about to explode :eek:

gavin319

11-19-2005, 04:16 PM

Dragonsgames, the clicking noise has been addressed before and I'm pretty sure it has to do with the charging connection. Just make sure that the ux and whatever you are charging it with are securely connected. My extended battery + cradle combonation was making my ux click like that and firmly connecting the cradle solved the problem. Just search for "clicking" or "click" if you want to know more about it. BTW The batteries I use are 2300mAh and they are working fine.

JA, have you tried modding one of brando's cradles? They are incredibly small and lightweight, so i think that a single ux or th55 battery would fit nicely in one. I'd say the cradle is about 2/3 the thickness of the ux, about 2/3 the length of the ux (which allows me to use the reset button without removing the cradle :)), and is a little over 3/4 the width of the ux. In comparison it actually makes my ux look big and I've always considered the ux such a small device. I just bought mine earlier this week though so I'm not really interested in modding my own cradle, but it is something you might consider trying.

dragonsgames

11-19-2005, 04:37 PM

The cradle is a charging case, and only happens when using the battery extender. Not thee EB40, but another one. :)

gavin319

11-19-2005, 04:55 PM

Yea, sorry my reply was unclear. I was referring to a problem encountered with using a battery extender (not the eb40). I meant to say my battery extender not extended battery. Anyways, my battery extender contains 4 rechargeable AA batteries (which is what I assume you have). I think the problem occurs with both the charging case method and the cradle method. I was just mentioning the problem to show you that it can be resolved and that it is unlikely that the batteries are the problem.

dragonsgames

I know it is charging, but the light won't light up... :(

11-19-2005, 05:46 PM

How many charges is 10,000 MAH? :)

gavin319

11-19-2005, 06:17 PM

Yea, I've only charged mine a couple of times since I had it, but I know that sometimes the light went on to say it was charging and sometimes it didn't. I knew it was charging though, because I could see the battery level rising over time. I'm not sure, it might just be another connection issue, maybe not. I don't think its anything to really worry about but I could be wrong.

dragonsgames

Guys!!, I've just did something I was trying to do from long ago and I've finally done it.

I've modded my EB40 to have a TH and UX battery in it and my UX to have a UX battery in it. I now have 2 UX batteries and 1 TH battery all powering my UX in a small size :). Here are some pics :)

Best part of all is that I did not have to mess with my UX at all. That means I can buy an EB40 tomorrow and use it on my UX just fine. I also can put a regular UX battery in my device and have no problem.

Silly Idea Time... I have seen a few ipaq 2400 mah 3.7v li-ion on Ebay for about $15 US including postage... Seems like a relatively easy job to interface these with the charging cradle... Of course, I can say easy because I have not tried it yet :)
I bought the USB charger from Semson and had that shipped here to Australia... Upon opening it I was surprised to see the sophistication involved in the SMD board... the voltage regulation is very well done, very smooth, and very little current lost to heat, I have modded it to allow any 6 volt source to be input, my main reason is I do a lot of solo hiking, around 10 days away from AC... A small sealed lead acid 6 volt is a great powerbank but it is heavy...

Anyways, nice job JAmerican, I have always enjoyed your tinkering :)

Just my 2 cents....

JAmerican

Thanks. After using this mod for sometime, I'm finding some issues. My device battery in my UX doesn't charge fully while my EB40 batteries charge. They also don't charge fully either but more so than the one in my UX50. I might have to replace a battery somewhere. I'm going to see how Hippo did his inorder his to charge.

JAmerican

I think its the TH battery. Going to try and replace it with the EB or another UX battery and see.

JAmerican

JAmerican

11-20-2005, 10:05 PM

I think I found the issue. I split the connection in the UX. If you look at my second set of pics, you see the internal battery is connected to the foil. This worked for outputting power but when it came to recharging, it interfered with the EB40 batteries' power. So I split the connection. I made one connection go to the foil and another to the internal battery. This way, the power would split in both directions, just like in Hippo's mod ;). Will do a more indepth review but so far after a complete charge and viewing one video, my power has not alternated as much as before.

JAmerican

11-21-2005, 04:49 PM

Ok, I tested my battery today and it worked with flying colors. :) I have pics below. As I said above, I split the connection and that allowed me to charge and power my UX. I also noticed that the UX can run without a battery connected. I connected my USB cable and removed the battery and it didn't shut off. Really cool. The battery meter says External Supply and Full.

Here are the pics I promised. :)

http://jamerican.net/1src/UX50/EB40BattMod/EB40Mod-Final3.jpg
The chip on the UX is the EB40's motherboard

EDIT: According to this site... http://products.sel.sony.com/semi/energy/productinfo.html

My UX + Modded EB40 has a total of:
1 UX --> 840mah
1 UX --> 840mah
1 TH --> 1300mah
Total of 3 Batteries at 2980mah OMG!! :)

DO NOT ATTEMPT WITHOUT PRECAUTION. I messed up my EB40 due to a stupid mistake. It can happen to anyone.

be carefull about the UX's alloy housing, they are always grounded
the tin foils were just too close, it may short the batteries & cause fire.

Do you see a problem Hippo?

EDIT: I took Hippo's advice. He was saying the UX case is alloy. Thus current can pass through the case. Since the foil is so close together, they might connect. So I reenforced the foil around the connector so that the case does not touch the foil but tape. :) Thanks Hippo.

Here is an image of my mod and some info...

This is a layout of the mod I performed in my UX50 and EB40. This mod will allow you to only charge via USB due to the other connectors are covered by insulating tape as well as the two prong positions at the ends of the UX connector is used to transfer current (3.7~4.2v) to UX to add to the mAh of the UX battery increasing your device usage time. It also works the other way around when charging.

Be careful, I recommend keeping the device attached to the EB40 at all times due to the foil can tear as well as placing the UX on a standard JC40 cradle with this mod will send 5.2v of power directly to the UX's (4.2v max) battery. Thus causing major issues. Be careful. It may look easy or it may look hard. DO NOT ATTEMPT IF YOU DON'T KNOW WHAT YOU ARE DOING. GET A MULTIMETER IF YOU DO TRY TO ATTEMPT THIS. HELPS A LOT!!

JAmerican

in fact pin 4 is ground already, you don't need to cover it & conect to ground by tin foil.....

I did that though. If you look in my image, you will see the negative wire connecting to the 4th prong foil. I didn't connect that before and I wasn't getting my EB40 to charge because the connection was broken. So when I connected it, it completed the parallel curcuit. I just charge over night and wake up to amazing power. I was watching a few videos and listening to music from 7:30AM to now (11:32AM). It wasn't straight but it was in and out and I still have 100% :). I was using BT yesterday for like 15Min and the power stayed constant. I really don't feel like replacing my UX anymore. I want to add another battery but I can't due to EB40 spacing. It can fit one more UX battery but it will be tight. Also, I have to remove the Release mechanism, which I'm not too fond of doing due to it keeps my battery on my device. My Release mechanism doesn't work but the actual thing that holds my device to the EB40 does. So I'm contimplating about that.

I notice that you having no charging ciruit & direct plug the batteries to USB +5V,
I would like to suggest you that buy a cheap standalone charger for moible phone battery for charge them up safety.
now can you feel the power when I mod UX cradle last year ?

cheers~

?? I don't understand? I don't I connect the USB to the same place you connected the USB. Thats why I expanded the area. It looks like the USB is directly connected to the foil.

Just for clarification. I don't connect the USB to the positive foil. I connect it to the first prong of the UX connector. Make sure to look at the expanded area for more specific detail.

Sorry... I mix up the "sandwich" mechanisum in the diagram

Its cool. I restated what I said because I wanted to make sure no one thought the way you thought. I usually keep my device at 1% brightness because I wear glasses and my eyes are sensitive to light. So this gives me more power than is shown below. For example. I went to school for 7 hrs and came home to see my device at 100% again. Its amazing. Usually. My device would be down to 50%. Once it was down to 30%. My device reaches lows of 88% and then jumps right back up even after multiple videos. I can watch 4 videos straight without seeing a change in the battery meter. If it does change, it goes to 100% and stays there again.

I think the battery is 3.7 volt 850 mah, it is printed on the battery, look at your photos JA, i can see a .7, and the last time i had the ux apart, i am sure it was 3.7.... So why can't we integrate an ipaq 2400 mah 3.7 li-ion into the equation?

Hippo what do you think?

I was thinking integrate into the charger cradle, just extend the thickness with a surrounding of plastic between the two halves? Do you guys know what I mean? Or are we better off with a 5.2 volt external battery that the ux sits on and charges via the normal charging pins?

Any thoughts?

From the second picture, you see it says NR70 but it came with a sticker saying NR70TH. I consider it a TH battery and have included that in my mAh total for my EB40 and overall.

I got mine from madmaxmedia (a member of this forum). I did a random search on ebay and saw people biding on it and bid $180 for it and got it for $177. When I broke it, I felt all my money had gone down the drain but after getting so many batteries over time from old UXs and just purchases in general. I decided to make use of them as well as my EB40 housing. For me, I'm amazed how it all worked out the way it did. I'll get a new test up for you guys when its done charging.

I did a test with my UX today. I left my charger at home and went to a Thanksgiving Dinner with my family. I started using my device at 3:30PM EST (GMT -5) with BT. I used it for about 30 min on Verichat. Then I viewed the internet on Netfront to see what was happening with the forums. After a few minutes of browsing I disconnected upon reaching my destination. I went inside and used my device for some time more. I played Sudoko for like 20min trying to figure out a 9x9 square. Then I played Bejeweled 2 for like 5 minutes. Then started watching music videos. I watched Cater To You (Destiny's Child), Diamonds From Sierra Leone (Kanye West), Run It (Chris Brown), then I turned my device off for like a few minutes. I then turned my device back on and played Sudoko once more. Then I connected via BT to the internet again and lent my cousin my handheld so he could use Verichat. Since he didn't know what he was doing, he pressed a hard button and left Verichat and went to the Music Player and played some music. Then went to RescoViewer to view pictures. I told him he would waste my battery power but when I got it back, my device did not even reach 70%. When I was leaving. I was using BT all the way home with Verichat and when I got home. My device was at 74%. This is amazing. :) I finally am not afraid to fully use my device to its potential. I did fear watching multiple videos for I thought it would go down quick. One thing I noticed is that the meter sometimes goes down faster than the actual battery itself for after I watch a video or play a game, it goes down then when I stop it goes back up. This happened with the UX battery by itself but never thought that it would happen with my mod. Most of the time, when I was playing games, my device was at 99% and 100%. When I watched videos, it went as low as 84% and internet went as low as 74%. I did not break 70% at all from what I saw. I was out of the house from 3:30PM to 10:00PM (6 hours and 30 minutes)

They would never fit because they are too bulky. They make the EB40 look thin.

As I wrote before, I'm sticking with SONY batteries because its a SONY device. They know how their batteries work and charge. I'm not an electrical engineer so I don't know the ins/outs of a battery just know about parallel and series circuits. I don't want to blow up my CLIE or myself for that matter. I also noticed that Hippo is sticking with SONY batteries so I guess he doesn't want to take a chance either. I don't blame him. If you want to use a DELL battery or something else, go ahead but beware of the consequences if there are any.

Takes like 2 hours to charge. Still feels light to me. Very light. Remember, its just batteries and plastic. It feels like an EB40. No bulging anywhere, although I had to remove the Release slider to add the last battery. I'm doing a battery test right now so when its done, will show you the new results :)

Hey all, I tried the EB40 battery with the TH battery and was disappointed. The EB40 battery caused my modded EB40 to be a total of 3.99v due to that is what it maxed out at. I’m not sure why but I found myself struggling today with power because my modded EB drained my device more than it charged it. I reached 11% today with my mod attached and had to do a emergency backup. Thats how bad it got. I'm going back to my older setup. I also can confirm that the EB40 battery is actually two batteries literally taped together but also I can confirm that its not the UX battery. At least, it doesn’t look the same. The EB40 batteries have a metallic cover and are held together by clear tape and a stronger tape around the edges that hold chips to the bottom of the battery. The 4 wires of the EB40 battery is not necessary. The two red wires connect to the same place and the two black wires connect to another place but both wires are in the same location. So I used only one of each in my connections but ended with a sad note. I am charging my TH battery now to see if it goes beyond 4v since I paired it with the EB40 batteries. I should but just making sure. As for pics…

I replace my UX battery with the Running Power (900mAh) battery. Its brand new so I hope it does better than the older UX battery I had in there. For some reason, my UX extended battery has not been keeping my UX interneal battery charged so I decided to switch out the foil and redo the connections to see if there was any loose ends. I'm charging my UX/EB right now. Will let you all know. Here's an updated pic...

You, yours is gonna be more powerful. Mine has old batteries in it. LOL and its still powerful. I just tested this new layout and came back with flying colors again. I didn't use my device a lot in school but my friend watched part of a family guy episode and I used DocsToGo to write part of a paper. When I left school, my device was at 100%. :) My device is always at 1% brightness BTW. My eyes are sensitive to light. Anyway, I was going home and watching videos. The lowest my device reached was 82%. This was due to I watched videos straight from the time I got on the bus to home. I watched 7 music videos on my device. When I got home, I continued to watch videos and my device reached 79%. This is amazing. Now my EB still doesn't charge fully so I'm going to change the foil again because I ripped it partically then direct it to the wires. Hopefully little to no current is lost with the foil replacement.

BTW, if you try this. Be careful. I had a spare UX to test stuff on. Not the charging aspect of my mod, but just the layout. I was also not afraid to destroy my USB/MS/Power Connector piece because I have two more. Just be aware that I had backups. Nothing I did led me to use one but just be careful.

Ok, I've done it. I've finally gotten your first mod to work for me. I disconnected Pin 2. Didn't fully cut it out but just disconnected it and added black tape between the connection points. Then ran a + wire to Pin 2. Then I moved the cable in the EB40 from Pin 1 to Pin 2 and that was it. :)

http://jamerican.net/1src/UX50/EB40BattMod/UXPowerMod.jpg

Its amazing how much more power this is over the Foil connection I had earlier. To give you an idea, I'm watching Office Space and its at 100% brightness in FMP and I'm at the part when they are in the restarant talking and drinking coffee. After this scene, the guy comes to them telling them they are gonna loose their jobs and my device is still at 100% :) Thanks to Hippo for the diagrams and question answering :).

In all my total battery mah gives my 4.6x more power than one UX battery.

With this mod, I can charge via my Leather case with my UX again. I can use my modded EB40 to its full potential since my USB goes to my first prong supplying it 5V or my leather case does the same thing. Pin 2 supplies the EB40's power, Pin 3 is not used because its the detector for the EB40's motherboard to the UX's motherboard and Pin 4 is the negative/ground connector.

LOL. I remember I was in your shoes once. Someone made fun of me but I see why now. You don't have 10,000mah. If it were a parallel connection, then you would have 10,000mah. But since you have a series connection, the voltage increases not the mah. Thats why your 1.2v batteries power your device because 1.2v x4 = 4.8v which is around the range your UX needs to be powered. The mah rating stays the same. So you have 2500mah + 840mah from your internal UX. = 3,340mah total.

I do have that extender but it got wet. It still worked but never used it again after that due to EB40 mod.

Crap. So now I need to find how to get 10,000 mAH...

The problem with that is that if you do a parallel connection, you get 10,000mah but you only emit 1.2v, which is not enough for the UX. If you want 10,000mah and 4.2v. You need 4 sets of 4x2500mah battery sets. You need to connect 1 set of 4 batteries together in a parallel connection meaning all the positives are connected together and the negatives are connected together but the positive and negative never touch. Then you need to take these 4 sets of 4 batteries and connect them in a series connection. Meaning the postive feed from one set touches the negative feed of another. Basically you end up with 16 batteries.

meaning all the positives are connected together and the negatives are connected together but the positive and negative never touch.
How do I keep connect them together and not let them touch?

Don't do what I said below. If you make the positive and negative touch and complete a circuit, you will see sparks and that could cause a fire. You have to be careful because you don't want Li-ion batteries to explode on you or around you for that matter. If you want more power, you will have to do what I said above but then your device will be very heavy and it won't be worth it.

OMG what power. All I have to say is that my device was at 100% brightness all day today. I started using my device at 7:30AM. I watched part of a fam guy episode. I listened to music with my screen on. I listened to music, went on the web with BT and still had 100% power. I played Sudoku and Bejeweled and still had 100% power. Basically from 7:30AM to ~6:15PM, my device was at 100%. Then it went to 99% then jumped back to 100% and sticked for a good while. Until like 6:30PM, it started to decrease. The lowest it got was 79%. Its amazing how long it lasted. This tells me that if I had my device at a brightness I like like 50% or lower, that will give me around double the stamina. Just letting you guys know. I will take some more pics and post it later for you all.

I have two regular UX batteries and 1 TH battery. That totals 2980mAh. The Internal UX battery is Running Power 900mAh battery which gives me a total of 3880mAh in all. The UX charges my modded EB40's 3 batteries and my internal UX battery. With the direct copper connection now, my EB40 is charged all the way to 4.19~4.20v compared to 4.10v with the foil connectors.

I've modded this project once again removing my internal battery and running my UX soley off of my EB40 batteries due to when I charged my unit, my internal battery received most to all the current. So, when it reached its 4.2V cutoff, my device stopped charging my EB40 batteries. Leaving my UX with 4.2V and my EB with 4.18 or even 4.10V. My device would lower in % in the first 1/2 hr of usage. I'm going to test this setup out and report back to you guys.

I forgot to tell you guys. I've made it so that the EB40 is apart of my UX. Meaning its on my UX 24/7. Thats why I did the Stylus-Free Reset Mod. I had to remove the Release Mechanism on the EB40 so it kept falling off. So instead, I jammed the release clip that holds the UX in place so the UX is always connected. It can only come off when I make it come off. If I left the release mechanism, then I would not be able to place the second UX battery in the EB.

I love the EB40 and always did. I always disliked the thinness while typing while when I viewed videos and listen to music, I loved it.

I think of it this way, the UX + EB40 is smaller than a laptop and the UX is basically that, a laptop. It way be larger than a TX or other handhelds but other handhelds don't have all the things a UX has.

I am actually thinking the VZ90 is better than the UX. I don't have to worry about battery life, and the screen is amazing. Also, the unit is faster and the WiFi is faster. :)
My text input is a little smaller, but I manage.... :D

For my personal usage, I would love the VZ for some time until I needed it on the road. Then I would love my UX again. Due to I absolutely need Bluetooth. WiFi is somewhat optional to me since I usually get WiFi at home only. As for Battery life, thats no longer an issue for me as you can see, lol. The screen is an on and off issue for me for I have mood swings about it. Sometimes I hate it, sometimes I love it. The 16MB of RAM has made it so that I'm more efficient when selecting applications to place in RAM or to put on my device. I've even used this same type of system with my 2GB MS. I have a BT dongle so I connect through that to the internet if necessary.

If the VZ was like the OQO, that would have been sick.

Ok, I haven't gotten home yet but when I do I'm going to change this config. Loosing the extra battery lowered my UX battery percentage all the way to 39%. Usually I'd be in the 50s by now. But it keeps alternating. Like it actually jumpted from 41% to 66%. I'm going to add the battery back but do something else.

The next setup, I'm going to cut the third pin (the EB40 detection pin) and use that to send my internal's battery current to the EB40 then add a wire from the third pin of the EB to the positive feed in the EB. This way, the EB batteries and internal UX battery is fully parallel connected. This way, when recharging, the charge current is sent to the EB batteries and UX internal. Thus charging all the batteries together instead of send the current to the UX and EB split up cutting off the current once the Internal is full.

Let me know what you guys think about this.

Nope what I had before was similar to his mod. This will completely parallel the internal and EB batteries. Then charge by sending the current to the EB40 where the current will be redirected back into my unit to charge the int battery. Its confusing but may allow me to get the full power I need.

Wow, I think I won't be opening my EB for a long time or my UX for that matter. I was applying this mod and three of the 4 wires connected to the pin connectors of the EB40 broke off. Being that I don't solder, I had a tough time setting it up where I could get the wires set up correctly. Probably took a good 2 hours. But once I got it and the current was flowing I connected my UX. Then I noticed that both meters where showing for internal and external. I took of the EB and opened my UX and made sure the black tape seperated pins 2 and 3 from the strip on the bottom of the white connector. Closed my UX, reconnected the EB and eureka. I hope it charges better and lasts longer. I'm back to using 4 batteries. 3 was not cutting it for some reason. My UX went down to 29%.

JAmerican

JAmerican

01-26-2006, 03:43 PM

Eureka!!! This fixed the issue. I added the Running Power battery back in my unit yesterday and made it direct the power to the EB40 (through pin 3 [cut from system] and pin 4). Then I made the EB pick up the currect and connect it to the parallel network of positive wires and then redirect that current to pin 2 [cut from system]. The battery connector (which I cut from the Running Power battery is then connected to pin 2 and pin 4 and connected to motherboard.

This system is better than the other two I had because the EB + UX Internal Battery all work together as one parallel unit when charging. Before, the current will discharging came together to power my unit but when I charged my unit, the charging current had less distance to travel to get to my internal battery so once my internal was 4.2V, it stopped charging. This caused my EB batteries to be left out of a full charge (thus not giving me full performance).

By being this mod this way, I get a 4 battery-parallel connection sending power to my UX, and when I charge, the 4 battery-parallel connection receives the current and will cut off once all are filled due to they receive the current at the same time.

The Advantages
-Full Charged Batteries
-Less wiring inside the UX
-More efficient with Pins available

The Disadvantages
-UX and EB need to be together all the time, or UX will not power on. [But if I connect pin 2 and 3 together, UX will power on if EB is disconnected.]

As for a battery test, I went today with my UX with the dial matched up with the A in the title [Adjust Brightness]. I am now home after 9 hours in school and my unit's lowest level was 96% battery life. Truely amazing. I was watching music videos today but only a few. I was listening to the Podcast 60 during school.

I also almost broke my EB again so I'm not going to open my device again since I've got what I wanted now.

I tested the battery today and it reached a low of 69% but jumped back to ~90%. I think this happened due to after it fully charged in the morning, I restarted the charge and before it stated the charge was complete, I disconnected my device. I'm going to test this hypothesis of mine tomorrow when I use it again fully recharged. Otherwise, the battery is more powerful with its output than it has in previous days. Really glad about that.

I'm having mixed results when charging now. Sometimes a full charge is when the UX is at 4.19v and charging ends quickly and sometimes, it feels like it takes 8 hours to charge and the UX reaches 4.20v. When it reaches 4.20v, my UX is at 100% most of the day. Even at 25% brightness. When it reaches 4.19v, my UX goes down to the 80% even at 1% brightness. So its weird.

Since I've mostly finished the main EB40 Mod, I've always wanted to add an LED to show the battery is being charged inside the case since the LED opening and CHARGE text is there already. So I did this but it FAILED. Now, it was not fully a failure. There was only one factor that messed it up, HEAT. Yep, I got a somewhat massive LED from a friend and added it to my EB mod like so...

I used the 5V that Pin 1 took in from the UX USB mod and directed it to the LED then out to ground/Pin4. After less than 10 minutes of charging, I felt the heat around the CHARGE LED area and unplugged my UX and took the LED out. I'm going to look for a 5V led that emits very little to no heat. Hopefully I can find some. I went to Radio Shack and they had no 5V LEDs only 6V, 10V and 50V. If I find any, I'll add it to my mod.

You make your "5v LED", just add a resistor of around 680 ohms (considering you are using 5v, this will provide close to 5 mA current, which is enough to drive the LED), you can use the resistor on either leads of the LED in series.
:)

wat about the heat issue or is this for a different LED?

MM MD

03-04-2006, 12:10 AM

The heat resulted from a high current flowing through your LED, it's not supposed to be connected directly to the battery like this, there is a current-limiting resistor as I mentioned. Most probably the LED is malfunctioning now, even if it is showing some light, I would recommend you obtain a new one, and a resistor of 680 ohms should give enough illumination for a red LED at 5v. Be carefull, the high current also flew through whichever source you were getting the power from (battery or charging circuit).

My device reached 4.19v after finish charging today. You think its a resistance thing? Every time I disconnect the battery from the UX and reconnect it, then charge, it goes to 4.2v easy. When I leave it on and charge a second time, its charges to 4.19v. I wonder why Hippo, m0nkeyb0y or yo (MM MD) have not experienced this.

JAmerican

I am not very clear about the exact details of your setup, but here are few points that might be pertinent.

1.Connecting with no soldering may be unstable, and actually results in variable quality connection, this might explain why parts of the setup seems to get different charging results (and yes, varying connection quality results in varying resistance in electrical terms)
2.I assume (and hope) that the batteries you are using all include protection circuits, these cut off the charging current when a preset voltage (~4.2v for most cells) is reached, it can never be the EXACT same for all cells, there is some tolerance that is built into that value, meaning you will have batteries stop charging at close, but not necessarily the same level. This assumes you are using identical batteries, things get more chaotic when using different ones (different current charging values distributed among them)
3.disconnecting the battery for a while, even without using it, usually results in a slight decrease in it's voltage. Reconnecting this again to the charging circuit will result in some more charging till the cut-off level is reached again, I am not sure of how much value that adds.

Would recommend you use solder to make all connections, this will take away the connection instability factor. Would also try to use batteries of similar characteristics if possible, especially if you are using many cells.

What happened with the LED adventure?

Just practice soldering small things around your house or buy a small electronics kit at Radio Shack. I just learned to solder this year in Electronics class and it's actually really easy to do. I also agree with what MM MD said. You're lucky you didn't explode your LED when you hooked it up that way. If you just add a resistor like MM MD said, you should be fine with providing the light without the heat. The heat is just an unwanted result of too much voltage (the whole point of LEDs are to provide light with little to no heat). I use the same LEDs in my electronics class and we always have to make sure to lower the resistance in the circuit to protect different parts of the circuit (such as the LED). Soldering your connections would really be a good way to go. It is very easy to have a malfunctioning circuit because of a poor soldering job, but it is even easier to have a problems with a circuit if you don't solder things at all. So basically, just practice some with a soldering iron and then move on to the circuit.

I saw some mini kits in Radio Shack when I was there the other day, but I cannot seem to find them online. If you go in and ask about them, they will know what you're talking about. I think they were just small kits where you soldered a few resistors, a chip, a buzzer, and a battery cable to a small circuit board...If I was mistaken then you can always find small soldering kits at other places. Here's one online: http://electronickits.com/kit/complete/misc/ck1102.htm

If you already have a soldering iron, you shouldn't get that one, but there are lots of kits out there. If you're school has an electronics class, you could just go there and ask to borrow an old circuit board...then you could just desolder the parts and then practice soldering them on again.

If all else fails, there's always ebay.

Something interesting happened. I removed all the older OEM-UX batteries out of my EB40 mod and left the TH and Running Power batteries in my UX and my UX charged quicker (expected) but lasts longer (unexpected). The older batteries (I guess) weakened the TH battery's potential. I will have to do more tests to see. This might just be the first phase (which usually gives me amazing battery life) then after that, its all crappy.

Big Thanks ! JAmerican. So the size is almost same as the UX50 internal one.
I just read the description on the EB40 saying it is indeed Li-ION Battery, not Li-Poly !!!! Strange that! Why don't they just use the same battery like UX50 internal?

So looks like I can use 2 NOKIA 7210 batery (removing plastic) to extend the capacity. 2 NOKIA 7210 battery can fit into the space, I think.
(I use that battery for my Treo180 before and it was great!)

Yep and the metal casing is positively charged (as all Li-ions are). Thus is the reason for the black plastic over the batteries. I don't use them due to their Li-ion nature. I don't want to mix Li-ion and Li-Poly. :eek:

(I use that battery for my Treo180 before and it was great!)

3rd party NOKIA 7210 Li-ION battery can carry over 1000mah. That is a plus for EB40.
Anyway, thanks !!

If I was willing to spend more money on my UX (which at this point I'm not), I would have redone my batt mod. I would have purchased two TH batteries and purchase a new UX battery so that they all start new. Then connect the all in parallel in my current layout. I may exclude the UX battery in a second test to see if the UX battery limits the current (which is something I experienced with my current EB mod but might be due to old battery. I may do some batt mods to the TX (maybe even add my TH battery to it ;) Who knows. We'll have to see.
