MacBook battery

[bamafever09]

Hey so i bought a 15 inch pro the other day from a friend. The battery was new and has 11 cycles on it and it says the health is perfect when i run coconut battery. For some reason when its fully charged it only gets 2 hours of time. I was wondering if anyone new if i need to do something to it since its a new battery or if im basically screwed and its bad? Thanks guys.

Time per charge is dependent on usage, so your battery is likely just fine. Search through the forums for any of the hundreds if not thousands of threads that have already explained this.

All depends on what you're running while on battery mode. Obviously running 10x programs while watching a movie etc. will drain it faster than idle'ing
