Alongside the 'How long did your iBook harddrive last for?' thread, I thought I would make this one. How long has your laptop battery lasted? Which laptop do you have? Have you replaced it? When? How much charge does it have left now? You can find this out with a program called coconutBattery, incase you don't already have it. My 14" iBook battery is 26 months old (original) and I've used 196 charge cycles. It has 3% of it's charge left... quite depressing.
