    In may I bought a new battery for my old 2008 MBP to get another solid year or two out of it before upgrading. I have been monitoring the battery life in terms of the mAh of it with a third party app called coconut battery. All of a sudden, it seems that overnight the capacity has dropped by ~1000mAh. Any reason why this would be or how I could fix this? Thanks.

    Try calibrating it by running it completely out, leaving it unplugged for 5 hours and then charging it fully.
