First time it charged in little over an hour, and I then proceded to run battery eater pro v2.70 when it said I had just 20 min over battery time :( But it stuck at 7,4% and it's still there now after an hour of hardcore processing. So I'm a very happy man! By the way I had huge difficulty getting the batteries out without destroying the cartrige, which I ended up doing. But I taped somthing up and now I'm home free :) Thanks again! Greetings for The Netherlands. Hey man,

I have recently needed to hack laptop batteries and this site come up in a search. I needed a really long runtime and got it. I was fortunate enough to get hold of some New Old Stock cells for cheap. 20Amp Hours on a IBM T41 goes a long way, unfortunately it does not fit in the original case. I can share a trick to opening up some packs, use a sharp hobby knife/craft knife/boxcutter to cut a wider slot at the seam so you can fit your tool in to start prying.

And sorry for saying: Appearently most of the people here have BY FAR NO idea of how dangerous this "soldering around" is in fact. BR Thanks for your infos jay !

I was afraid it would take days to get a reply, but a few hours after sending my message I checked your site again and here was your reply. Thank you! I guess I didn't explain myself properly about discharging the cells or not before removing them. What I meant is before putting new cells in my battery is it better to have the old ones fully charged so the electronics on the battery will see the cells as 100%? Does is make any difference at all if the old cells were at 100% before being removed? Hopefully, this is clearer this time. :) Hello Jay,

If you are just going to throw them out, you could discharge them lower than this, but I don't see a big point in doing so. Assuming you recycle them in a proper battery disposal location, they will know how to handle them correctly, charged or not. If you purchase better (higher capacity) cells than you currently have you should get a better (longer) run-time. Jay Clive:

If I remove them when they are supposed to be fully charged is that a problem? Also, if I get 2600mAH cells instead of 2400mAH ones like those in my battery, will I get a battery that lasts longer or am I just going to waste money because the laptop will treat them as 2400mAH cells anyway?

Most smart chips memory is erased when power is lost and therefore wont charge anymore. Never disconnect power from the chip hook up a secondary source with a 100k ohm resistor and dont remove it until your new pack is hooked up to the chip.
