I bought a 1900 mAh battery from mobilfun.co.uk, appears as an official O2 battery but have had to send 3 back.
The first did not charge at all, either in the cradle or the phone.
The second charged fully in the craddle and lasted 2 hours before going dead. It would not recharge in the craddle or through the usb cable - battery not seen.
The third again seemed to charge OK in the cradle but when put on the phone it immediately caused a hard reset (internal battery at 100%).
The company has changed the battery each time but I'm at a loss to understand why this is happening. Is it a bad batch of batteries or the phone?
There were no instructions with the battery to indicate the need to charge the battery on the phone first instead of the cradle so I used the craddle.
Any adice gratefully appreciated.

Hey guys! Just grabbed an Innocell for $45 on eBay, read through several threads and had a couple questions. First, I did not get a charger with it so whats the best way to charge it with my evo, Laptop USB or Wall USB, or should I drop a few bucks on a charger? Second, will it charge completely in my phone(and without blowing up)? Third, what is the heat like, with my stock battery it gets hot enough to make the kickstand & back of the phone pretty warm(only if I am say playing a game while charging, surprisingly it doesnt get warm using GPS like some other), so just wondering what the heat with this bigger battery is like.
Well when I purchased my extended battery it came with the external charger bundled with it. There have been debates all over about what is the best way to get a full charge without that initial 10% drop off. I always use the external one to charge my battery with great results. Haven't tried using USB but this battery, even without a full charge is still a beast. I'm a heavy user and I still haven't been able to kill it.
my captivate is v2.2 froyo rooted w z4 and lagfix, My stock battery barely lasts me through a night at work,
I ordered a 3500mah battery from ebay and when i received it I charged it overnight with my phone off....
The next day was a miracle! Battery stayed at 100% for 2 hours, by the end of the day I still had 60% battery left!
I read that the first couple charges need to be cycled so i tried to drain the battery by playing a movie over and over with screen brightness and volume at max.....
the battery lasted forever, after getting it down to 7% I charged it overnight- sameway with phone off, but now nomater what i do it only lasts the length of a stock battery.
I tried unplugging,plugging back in, phone off , phone on, waiting hours after it says 100%(on charger overnight) and tried ac and usb charging, but it just isnt seeming to charge all the way.
I was going to buy a second extended battery and an external battery charger but all the external chargers i see on ebay say are only good for li-ion batteries up to 2000mah, plus i had to modify my otterbox defender case to support my new battery and it would be a pain to have to take case apart everytime i swap batteries.
Ive been reading for days about what to do to no avail, all the external chargers i see arent rated for 3500mah capacity and I wouldnt mind flashing a custom rom that would support extended battery charging but the more research i do the more confused i get.....
Is there a kernal out there that is stable and supports charging these batteries with no bugs or issues????
What custom rom would be best?
please help......
any info is greatly appreciated
there is no such thing as a rom that supports extended batteries
the phone does
the chargers ALL work for the extended batteries there is no capacity rating limit on them. they do have a charging rate but it is around 350 to 800 mA/H and the batteries are acutally around 2500 mA so devide 2500/500 is 5 hours to charge.
[Review] 3500mah extended battery pictures heres my review - and would have been a better place to post and ask.,...
Cheap Chinese Battery Charger heres my charger. works fine.
[Mod] Battery Charger - USB Upgrade Mod heres my charger mod to charge faster thru USB. 800 ma/h so under 3 hours for extended,
charging on the wall charger or thru the phone takes longer than a regular battery.
charging thru the phone on USB is faster with the official samsung or with a hacked usb charger like above
i get upto 60 hours out of my battery. - under volted properly and custom kernel options..
you may want to wipe your battery stats. but i switch back and fourth no problem.
or your battery has a bad cell. those extendeds are just 2 batteries linked together.

there as an app in the market to wipe battery stats I forgot what its name it might be helpful to you since you're on stock froyo. probably your phone battery stats was in line with your oem battery so to maximized your extended batt you will have to wiped out the current battery stats for your phone to adjust to your new extended battery. I will post the app name later if I could find it. since you are rooted it will be of use to you.
edit: ok I found the app it's called battery calibration by nema download it from the market give it a whirl and observe how it goes..
i remember reading about such an app for rooted phones on a different forum but someone replied saying that it would wipe battery stats but still wouldnt help since the phones stock software is written to only charge a battery to 1500mah then it stops charging.....
Do u think it would work or am i screwed unless i flash a new kernal?
would be worth a shot.......
Is it best to wipe battery stats when extended battery is drained b4 charging.... or when fully charging .... or does it matter?
thanks guys for the fast responses!.....
so any of the chargers that fit my battery should work then.... they have the same specs as yours... so i will go ahead and order one for now,
I guess the surest way to know i am getting full charge would be to use the external charger...
So an extended battery should fully charge in the phone with no issues? Ive read so many forums that say a custom kernal is only way to charge them 100% in the phone???
no.. to charge at 100% speed. and i havent heard of any kernel for that in the captivate forums...
ie using the official samsung charger (usb) will charge at full speed the one that comes with your phone is 750 ma/h. if you plug into a non official charger the phone will only let in about 350ma/hour through the usb. or hack it.
i have the usb that came with the phone.... so i will get 750ma per hour if i connect usb to computer only or it will charge that fast on the samsung wall adapter also?
the wall adapter only!
the phone has to see the official CHARGER to charge full speed. or hack the other CHARGER, other wise it charges at what it calls "usb" so charging using usb would be slower too. if you read the [mod] link above, or all the other times i said CHARGER above, you would understand,
alright....thanks bro
charging via usb from your pc will always be slower than using a wall adapter.
not true.
aftermarket chargers (not samsung) wont charge the phone any faster than the pc
....unless you mod it!
[Mod] Battery Charger - USB Upgrade Mod
unless the middle 2 pins of a USB cable or the charger itself has the 2 pins shorted the phone charges in USB mode 350ish mA/h with the OEM chargers or a modded charger it charges in "AC mode" upto 1100 ish mA/h
the charger that comes with it supports this mode but only 750mA/h max output.
....
.......

ya.....
Another attempt at trying to get an external battery that works:
Vaas VM50 5000mAh Dual Port Rechargeable External Battery Pack w/ 6 Charge Tips
It's enough to charge 1 time, although you have to unplug it when charged.
Here's the biggest problem: it seems that if charger has less juice left than the phone battery, it starts sucking the battery out to charge itself.
Yesterday my phone had 46% around 1am at night. VAAS had 2 out of 3 lights on (so above 50%?). When I woke up this morning - my phone was completely drained, and VAAS had 1 light on.
Don't buy it, it's crap. You may get 1 charge out of it, and even then you can't safely leave it overnight.
I am having similiar issue with RAIKKO 5200mAh pack. When you plug it in without turning the charger on, it will look like it's charging, when it fact it will discharge (fast - something like 400mA even with screen off). The same happens when it runs out of juice - it will stop charging, switch off and start "draining" the battery.
When I tried this on my friends Desire HD, it said "charging voltage is too high" and refused to charge until I actually turned it on. So it is an error in both the charger and the phone...
I guess your charger has the same crappy chinese circuitry :-(
I've been successfully using the new Trent 5000mha external battery pack. I got it of amazon and the thing has been faultless in the 2 years I've owned it. The cells are starting to wear now but I can still charge my phone 3 time before re juicing is needed. I think it was around £13 so it was a bargain as well. I use mine to charge the one x ok, but my Samsung galaxy tab it keeps level , I think that machine need 2 amp to correctly charge.
The pack has two outputs, one marked iPad is 1amp and the other is 500mha. I've never had it back charge a from a phone. Just make sure you turn it on otherwise it won't charge the device - the red light come on but no charging happens.

the usb port died a while ago and ive been charging the battery external, i have 2 batteries plus the charger. i would like to continue to use it after the phone dies, so wondering if theres any other phone that i could still use the battery on
