Hi.
I received my new battery today Wednesday, I ordered it on Monday so great shipping time.
It is a 12cell 66000mAh replacing a 8 cell 44000mAh battery
I did not have the money for a OEM battery as they cost so much plus it`s an old laptop and not worth spending a fortune on, So i searched for a cheaper alternative.
Battery cost £36.99 + 4.00 recorded shipping, I payed an extra £2.00 for special delivery.
I installed the battery and began charging it.
I have a mains energy monitor so i could keep a eye on how much power my laptop was using while charging the battery.
For the first 1h45min it was using 53 watts and then it dropped to 22 watts about 10mins after that the wattage was alternating form 22 to 13 watts and back and forth , At 2H5M it changed to 13 watts and after 2H10M the battery was fully charged.
According to mobile meter the
Remaining Wattage is 97680 mWh
Designed Capacity is 97680 mWh
Full Charged Capacity is 97680 mWh
Battery Wear 0%
Voltage 16725mV

With Toshiba Battery save running on maximum, I get a estimated battery life of 2H57M thats not bad on a P4 3.2ghz processor as they eat the battery`s
I have not had the chance to discharge and re-charge the battery, but the initial reading look good!
I got the battery from the website below.
Regards
John.

At least the seller has faith in his product and backed it up with a year's warranty.

12 cell? Holy cow!

You have to be careful with some on-line sellers, but this site seems to be OK.

Nobody got a opinion on this, I was told by a NBR member not to use an no OEM battery as it might damage my latop!!
-
I've been using an ebay battery on my Thinkpad X31 in addition to a real IBM battery. Seemed fitting since I got the laptop on eBay too!
No problems so far and I've had the laptop almost 2 years and the battery not quite as long. I'm not sure I'd go the same route for a more expensive laptop but since it was relatively cheap used on eBay I was less concerned about the battery and just needed another one for a cheap price. -
Three hours on a 12-cell still attests to how badly the Pentium 4 sucks, IMO. Still, glad to see that your purchase went smoothly; many non-genuine batteries are defective.

It sounds like that was some one who has been influenced by scare tactics.
Although the non OEM batteries for Nokia phones used to be very bad. But they would not damage the phone. -
Do you remember the exploding batts? While those might of been OEM does not make Ebay look good to me. -
batteries contain an internal control board with info about the battery. from what i've read in other posts here at NBR those generic batteries and even some brand name batteries do not contain the same info on the internal battery control chips when compaired to the control circuts of batteries sold by the OEM.
now wheather or not a battery could do damage..... i guess it could be possible especially if the off-brand battery's circuts allow too much voltage to leave the battery... it could be like a mini power spike i guess.

Hi.
I have done 2 full discharge-charge cycles in low power battery mode and i got 2h 29m before the laptop shut down, I was browsing the internet with Wi-Fi. -

Dammed, I now have 3% battery wear after only 2 days

John, do you still have the old battery around?
If it doesnt work, take it apart, and you will see a chip inside, usually made by ST, or Maxim. Look up the chip online, and short it. You will reset the clock of the battery.
Most batteries like Dell batteries for example are set to die after the warranty ends. Simply take the battery apart, and short the chip, and it runs just like new again.
I have been doing this for a few years, and my batteries are running for 7 + years. I have some batteries which are 12 years old, still running strong, caus ethey dont have these chips in the batteries.
I am sorry to hear yours has 3% wear already. If it helps, my dell battery had 5% wear from the minute I first booted it up.
Anywho, I wouldnt trust the monitoring software so much, cause they are not very accurate. They are basing wear of internal and output voltage differences and the internal resistance of the batteries.

^ The batteries are deliberately designed to fail? How do you short these chips? I'd like to know more!

You just need to open the battery pack up and locate the chip which controls the voltage distribution for the cells. Usually its just a small microcontroller. Just find the chip, and go to the manufacturers site, and you will find spec sheets on them, which you can find from their.
Usually searching digikey, will find whatever you are looking for, and they usually have a spec sheet attached. Simply read the sheet, and you will find out how to short it for resetting the microcontroller.

the god of the internet demands explanation -
I know Dell does this in their batteries. I have done this on old Latitude batteries and Inspiron batteries. I have never tried this on a non dell battery, but it has worked for me on three different types of batteries.
When they stop working, I simply take them apart, disconnect the cells from the microcontroller, clean off the oxidization from the wires and leads, and than short the microcontroller, put it back together and it works again.
Its dangerous, if you dont know what you are doing.
A few manufacturers, like Clevo (they use SmartBat batteries) Sony, Hp and others are preventing people from doing this now, cause they are using plastic to thermally mold around the batteries, so the user cant take them apart, without cutting the battery shell. The power of microcontrollers is amazing, and keeps bringing people back to them, to buy batteries, feeding more revenue to the company.
There are ways to jumpstart batteries, you just need to know what to do.

i knew there was a logical reason to leave my laptop plugged up all the time
my battery is still at 42,335 mwh out of 44,400 so that's pretty good for 10 months -

Hi.
K-TRON , I have taken pictures of both sides of the PCB, can you have a look and tell me which chip needs to be reset and how to do it!!!
Thanks
John.

I have tried getting the datasheet for the BQ2931OPW and the BQ8011DBT, but I have not been able to find them online. Your battery is an 8 cell and you can tell cause of the 4 TPC8107 current regulators on each side of the PCB. One of them per cell. You dont need to mess with those, just the BQ2931OPW and BQ8011DBT. Why your battery has two microcontrollers is beyond me, the ones I have operated on have one microcontroller, and they all happened to be Maxim chips, so I was able to get the datasheets.
I dont know who manufactures BQ microcontrollers, I have never heard of them.

Hi
Thanks for tying K-TRON
My battery new wear is now showing as 7%
