Hey,
I have a thinkpad A31 (Which I love & it plays aoe3

pentium 4 1.7GHz (upgraded?), 768mb ram, 40gb 5400k rpm hdd, DVD ROM, ati mobility radon 7500 16mb.
I'm experiencing a odd problem, I bought a new battery from eBay for £31.49 free p&p and it came today, ran though the charge cycles etc.. And it works for 1.5-2 hours (good enough for me

and when checking it apparently has worn away 25% of capacity! Is this because the thinkpad can't accurately read third party batterys???
Or is my battery broken?
The weird thing is that every charge it lasts longer!?
Thanks
