I own a IBM ThinkPad T41 with the stuck out 9 Cell Battery.
I use my laptop at the desk mostly, and have it on the charger. Will the AC Adapter Over charge my battery? I sometimes unplug it from the laptop when I have it at the desktop but just wanted to know if it stops charging the Battery at 100% or if it Over Charges it. My battery when off the charger running on the battery don't seem to last long, maybe a 1-1/2Hr it lasts.
lenovo said they still make the batterys for my model but I rather keep mine due to the price of the batteries for a laptop $99
