Ive been browsing for a new laptop battery for my hp dv6256us laptop, and i need my laptop powered for an extended period of time especially at school during lectures, so im planning on purchasing a 12 cell battery. And then i came across mAh (milliamp hours) of the battery, i found one with 4400mAh and of course 8800mAh, and the 4400 is cheaper. i was wondering how long teh 4400 would probably last me after a full charge?
