Battery Help!

[ZiggyZidel]

Hi guys
so I have an early 2008 macbook 2.4ghx 4GB ram stock hard drive..
anyways I run coconut battery and usually my battery health is 97-100% (had the battery replaced a year ago) and then yesterday it suddenly dropped to 67% and said replace soon, a few hours later it was back to 97% and all was good.. until this morning when I realized my battery says 100% even though its been running on battery for over an hour.. does anybody know what the problem is?
Thanks!

Your battery health will fluctuate up and down over time. Calibrate your battery to make sure your readings are accurate. If you continue to have problems, try resetting the SMC. This should answer most, if not all, of your battery questions:
