    My MacBook battery is messed up. I keep track of it using Coconut Battery as well as the iStat nano widget and the battery health indicator keeps going up and down like an old whore. The original battery capacity is 5200 mAh, and sometimes it reads it's at 97% of the capacity, then other times it'll plummet down to 34% (it was reading that for the past couple of days) and now it's gone back up to 79%. What gives? This is just one of the many battery anomolies I suffer. Others include the battery giving out while still reporting 50% charge left, or putting my MacBook to sleep with a 50% battery just to open it up a few hours later and have the battery be dead. There's only 200 charge cycles on it after 15 months so I can't figure out why it has amnesia and can never remember what it's proper setting is supposed to be.

    I calibrated it the other day, which is what resulted in it saying I only had 34% health left after it was recharged. I'm thinking I should just call AppleCare because if this thing continues to mess up it'll put a damper on taking my MacBook to school to work on papers.

    Batteries are consumables and aren't covered by the warranty. 15 months doesn't seem that long, but the battery will drain out after 2 years quite quickly depending on how you treat it.

    Actually, I just realized that my MacBook is almost 15 months old, but the battery is either slightly less, at the mark, or slightly above the 1 year mark since last August I had issues with it and had to get it replaced by Apple. Ugh. Whatever. I'll call Apple at some point and then if they can't do anything I guess I'll just have to get a new battery within the coming months.
