OK, I just got and tested the LG Chem battery that VincentChon brought to our attention. Will post full results in the "Battery Life Incredible" thread later today, once I get to my Hotsync'ing PC to transfer the Memopad results. The envelope's return address was from "Chon, xxxx", same last name, and the ebay seller is "vincent_vango," same first name, so we might deduce that VincentChon is the seller. Battery came with a nice big tri-pointed screwdriver, no retail packaging (some soft foam wrapped around and scotch-taped), had to sign for it.

Brightness at 100%, BatteryTime run after very first charge: 4:35:59.

I slogged through the 18 pages of the "Battery Life Incredible" thread, and here are the top results for those I could determine were tested at 100% (there was one salesrep test of 4:44:28 but without brightness level specified).

5:13:13, Sony, DanT, tested 7/06, new battery
4:55:28, Sony, DanT, tested 7/06, new battery
4:54:15, Sony, winexprt, tested 8/04, 3 days old battery
4:38:36, Sony, Aces, tested 1/07, new battery
4:35:59, LG Chem, jj2me, tested 2/07, new battery
4:34:42, Sony, Aces, tested 1/07, new battery
[Several 4:30s new Sonys tested in 2004]
4:29:17, Sony, salesrep, tested 2/07, in a "hardly used" TH55 of unknown mfg. date.

Conclusion (based on an LG Chem sample size of one!): Sony's the best, but the LG Chem is competitive, especially based on the most recent new Sony tests by Aces, and in this thread, marcinm123's 4:28:58 posted 1/07 (but BatteryLife date of 1/06??)--perhaps the Sony stock is getting old? mAh rating (1380) is still irrevalent when compared to Sony's 1000 mAh rating. LG Chem battery from vincent_vango is about half the price of a Sony ($16.99 + $5 shipping to U.S. vs. $38.40 + ?? shipping). I'm satisfied, thank you VincentChon.

[EDIT: I could not find any mention of the screwdriver in the eBay listing. Its inclusion was not a mistake because it was listed on a short contents list on the outside of the package. Just a warning that maybe other orders may not get the screwdriver.]

[A side note about ultra-long battery life: My 3.5 year old (open box, so may be older) black-and-white Sony Clie SJ20's battery seems to finally be deteriorating and need replacement--the charge is not lasting as long as I'm used to. I tested it with BatteryTime at Contrast Level set to midpoint (there's no brightness setting) and got 6:24:02!]

04:35? Seems good enough for me, for what I've read on that post, that's a lot over the standard battery life for batteries found on ebay.

And a tri-pointed screwdriver was included? Come on, seems a great deal!

Please keep us posted on your results, tomorrow is payday and I might go ahead and order that battery!!!

Thanks once more for your effort

Hi!

There was obviously a mistake in my previous post, the test run with a new Sony battery was January 20th 2007 not 2006 I mistakenly put the 2006 instead of 2007 after the hard reset caused by the battery replacement. THX for pointing that out

Well, LG is not bad at all if it actually outperformed my new Sony cell :P and moreover it's cheaper!!

I'm charging now to see how is the new battery doing after a month of normal use, I will soon post the result.

However I am curious to see the results of other LG cells for TH55...

Maybe we would be able to calculate the difference in mean of the BatteryTIME Sony vs. LG and it's significance

So - if anybody gets another LG battery please post the results!!

psau3

Keep in mind that while Lipolymer cells do not exhibit the old NiCad / NiMH 'memory effect', they do have a finite life, no matter how they are used. After around three years, you will notice a substantial drop in capacity. Buying up Sony cells to hoard in the fridge might not be a particularly sound investment.

salesrep

I bought one of the LG batteries and the e-mail indicated that it would come with the screwdriver (although I already have one.) As soon as I get it, I'll test and post results as well.

Just got my new LG battery yesterday and after a full charge and restore here are the results:

T:04:46:03 B10%,375V

Of course, brightness at 100%. Very impressive for around $20 including shipping and the screwdriver. I believe that's the best time I've ever seen from my testing.

If it and the truth LG cells, then capacity by the seller are overrated on 100 mAh.

Hmm, that's interesting.

But still it is the best cell we have seen among non-Sony batteries - it performs at the least as good as the orgininal one or actually outperforms it...

olderTechnology

I ordered one based on all the discussion here. Thanks for keeping this thread going.

Aces

Just to be clear, the "eurus-wings" (eBay) battery I originally bought (May of 06) was described as 1400mAhr, yet in my TH-55, was only getting 3:35 with BatteryTime, brand new. Whereas the new OEM Sony battery I bought in January of 07, is described as only 1000mAhr, yet in my TH-55, got 4:34 with BatteryTime.

I wonder where the standardization is in mAhr ratings? Perhaps if I used these batteries until the voltage is significantly lower than the TH-55 can tolerate, I'd get 1400 & 1000 respectively. And some would argue that with the backlight setting at a lower level (mine were done with full backlight), maybe the 1400 would out perform the 1000.

What really matters, is how it works in our devices. So BatteryTime results mean a lot more to me, than manufacture's mAhr ratings. And while full backlight and continuous on, isn't how we actually use them, at least it's a standardized test to rank one battery as better than another.

1400 chinese mAh < 1000 normal mAh

VincentChon

Yes, you are right, China's cell/battery usually over mark the capacity.
That's why I only sell the batties produce by SANYO & LG cells.
Other country's battery always under mark the capacity.
And the TH55 battery by LG has been test by machine to achieve 1380mAh
LG battery capacity usually under mark 6%, 1280x6%=1356.8mAh.
And the Technical Spec for a few years, the technology improve, the battery usually more juice that before.

Thank you VincentChon, much appreciated that you have made these available to us.

I've just brought the LG battery from Vincent.

Wow, 5Hour & 16 Mins
The voltage comes back to 20% for quite a long period of time (I didn't count it)
This is an E1, hard-reseted with bluetooth and beam receive turn off and full brightness during the test.

The battery package come with a screwdriver.
The price seems to have rised a bit now but I think it is still a very good deal!

Thanks Vincent.
