Hi everybody,

First of all I must say that as a medical student I find my TH55 very useful.

TH55 and my stethoscope make without a doubt two most important accesories in a hospital

So seeing my TH55's battery life drop down recently made me a little bit concerned... A few times it happened that in the end of the day I was out of power to acces Memory Stick, where I have most of the apps loaded.

This is the BatteryTIME results from Dec 2006:

BatteryTIME 28. Dec 2006;12:04

DISCHARGE

Time;Battery;Voltage
00:00:02;100%;420V
[...]
T:02:34:29 B10%,375V

December last year I read 1src.com posts about battery options on the market and I decided to get the original Sony battery from servicesales.sel.sony.com.

The sad thing to see was the fact that they do not accept non-US issued credit cards and do not ship outside US.

Fortunately, DanT helped me out, he ordered the battery and resent it to me to France (I study in Poland but this year I'm on an exchange in France). The entire process took about 3 weeks.

Great Thanks DanT!!

Yesterday I was ready to install the battery. I decided to share my experience with you and took a few pictures

1. Ready to go!



TH55/U, tri-blade screwdriver from Brando and a new battery kit.
At this point make sure you have a backup, cause battery swapping will cause hard-resetting the device No, no backup battery in that case

2. The old battery after opening the battery compartment



Notice the black strap, we will use it to pull the old battery out. The new battery doesn't have a new one so I decided to remove it and stick it on the new battery.

Now, there's the tricky part. Some users reported that the battery became attached to the ribbon connector wihich runs just below the battery and pulling caused ripping it out... I continued with extreme caution, however in the middle I felt it is a little bit stuck, so I moved it a little bit side-to-side and then delicately pulled again. At this point if you feel any unusual resistance you might want to open the entire case to prevent damaging the connector... However, this seems to be rather isolated problem.

My battery was out in a few seconds after, but THERE WAS indeed some RESISTANCE - I guess that's completely normal. Just don't try to force it and it should be fine

3. Quick check if everything is fine



After removing the battery I checked to see if everything worked fine: LCD, digitizer and hard buttons. Thankfully it was - as it seems no connectors broken this time . At this point make sure you SWITCH OFF the device before attempting to unplug the battery!!!
4. The battery compartment opened



Here you can see that the ribbon connectors afer removing the battery are located quite loose in the compartment... forcing the battery in that position would SURELY break them - keep that in mind

So what we can do?

TH55 forum users suggested to use a piece of a business/id card cut to the width of the battery to slide the battery in while keeping the connectors away.

5. Ready to insert the new battery



Here you can see a piece of a business card in the battery compartment inserted to prevent damaging the connectors. I just slided the battery in, there was slightly more resistance than when removing the old battery.

6. The new battery in



At this point I wondered if I could possibly leave the piece of business card inside to prevent the connectors becoming attached to the battery itself, but finally I removed it...

Now, before plugging in the new battery wait for a few minutes to let the capacitors discharge - some users reported that plugging it right away made TH55 not to wake up immediately... I waited around 10 minutes which turned out to be enough.

7. It's alive



Right after I plugged in the connector Palm logo appeared on the screen. I closed and screwed the lid and left TH55 to charge all night.

That's the new BatteryTIME result:


BatteryTIME 20. Jan 2007;9:02

DISCHARGE

Time;Battery;Voltage
00:00:02;100%;420V
[...]
T:04:28:58 B10%,375V

So I gained 2 hours, not bad at all


I hope you enjoyed this quick guide, good luck with battery swapping and have fun with your TH55 (longer with no need to charge)

DanT

Wow, what a very detail procedure you got there, Dr. Marcin. I got to add this procedure in the TH55 spareparts center thread as reference for do-it-yourself TH55 battery changing procedure. Good job! I can see you'll be a good surgeon too!

Good job,nice!

Yes, thoroughness is the key to doing well in any job, but I especially appreciate it in my surgeon!

A question: What replacement battery gives 4:28:58? Was it a Sony?

DanT

Yap. I got it from Sony for about $50.

Ah, the best. DanT, you treat your TH55er clients so well. Wish I bought a Sony as my spare instead of the new Cameron Sino in the fridge.

Hello everybody ^^!

Here is the battery for SONY NR/NX/TG/TH Series, and cheaper than Sony. More juice.

1380mAh made by LG Cell

http://cgi.ebay.com/ws/eBayISAPI.dl...em=150015859101

Any question, please feel free to ask me ^^!

Thanks!

Vincent

More juice, perhaps, but Sony uses magical pixie dust to make their 1000mah batteries solidly and consistently outperform all other aftermarket replacement batteries that I've seen. . .although I have not seen this one before. Anyone else?

Why don't you show what LG cells' Battery TIME discharge test look like?

The other 1400 mAh batteries made by Cameron Sino have been disappointments. Check out this Battery life incredible thread. Many TH55 owners tested such batteries and were disappointed.

Hello DanT,

Thanks for your suggestion, but I haven't TH55 right now ^^!

I just using TT3 while now, LG battery is our main cell that I use for

modification for PDAs ^^!

And the battery will include the screwdriver for TH55 also.

Below is the LG Chemical homepage for the cells reference.

http://www.lgchem.com/about/business/Information.jsp

Just let you have another choice for brand cell, not other unknow cell for

PDAs ^^!

DanT

And how is the Battery TIME discharge test of LG Cells' on your TT3?

Hello everyone, I have just confirmed that the reason my beloved TH55 stopped turning on is due to a completely DEAD battery - that's a relief!

I already went through both of the discussions on proper battery replacement... I want to go for either the OEM Sony, since it has GREAT reviews from all of you or the cheaper 1100 one, (power runner?) that I haven't been able to find on Ebay. If anyone has the link, that would be awesome!

And now we have a third contender, this "LG CELLS" something-something.

Has anyone else tried it already? If you did, please go ahed and post your results, I'm sure there's plenty of people still waiting to get a response in order to make a choice.

Thanks for all your assistance & have great day you all!

DanT

Here is one eBay auction for Power Runner Item number: 170080780054.

I ordered one two days ago--curiousity got to me. It's coming from Macau, so it might take a little while to get to me in the U.S. Then I'll test and post results.
