Hello all, Since I bought my early-2008 MBP new, it has gone through two replacement batteries. Both times, the battery would say "Check Battery Condition" and were replaced under warranty/extended warranty by Apple. I was told by the Apple employee that they switched battery manufacturers and that my new one should be better. However after only a few months of use, according to Coconut battery, the battery capacity is down to 83%. I've always done battery calibrations as well as not keeping it hooked up to the wall charger excessively, etc. Is it just a bad battery design, bad vendor or what? I'm hoping to get a new MBP maybe next year or so, hopefully the new MBPs don't have battery issues like mine.
