So I got this battery that dies even when the battery meter (LEDs and meter) registers a charge dies after a few minutes of use. Out of warranty too.... (Apple was damn sneaky about it though. I was covered by the 1 year warranty, but I was out of warranty because the battery had over 300 cycles according to their hidden company policy. Total BS.) So I was wondering if I should go with the fastmac battery or the apple battery? Also I was wondering if I need to buy a previous generation battery for my previous generation mbp or can I just buy the current mbp battery and slap it into my 2.2ghz coreduo 800mhz fsb 128mb vram mbp? *I read in the reviews on amazon that the fastmac battery is not "set up to work with" the core 2 duo macbook pro. Some guidance would be greatly appreciated. thank you.
