I have a late 2008 MacBook Pro. I recently purchased a new battery as the one that came with it wasn't holding a great charge. I think it's health was at about 40%. Anyways, I'm up to 250 cycles and my health is already down to 62% ... is this normal or is my battery crap? Thanks! P.S. I've been told that for a better battery life that you should let the battery drain instead of draining halfway and recharging, so that's what I've done since day 1 on this new battery. I'm beginning to think that's B.S.
