My 22 month old MBP's battery isn't holding charges as well as it used to. I've tried re-calibrating, but my batter capacity according to coconutBattery is ~17%. The batteries from the Apple Store seem to have pretty negative reviews. Where have you folks gotten new batteries? Any advice on what to watch out for? Thanks much! Whoa, just read the Macrumors guide on laptop batteries. It says the life span should be around 300 load-cycles! I'm only on 179 load-cycles and I'm getting around 17-20% capacity!
