    I just got my MBP yesterday, and according to Coconut Battery, the MAX charge was already 4545 instead of 4600 after only 3 battery cycles. Then after unplugging it, it said 4693 instead of the original 4600. Is it typical for the battery to jump around like this?

    Thanks

    Yes. It's fine. The chip that monitors it isn't perfect.

    Its nothing to do with the chip that monitors the battery, its Coconut Battery. Thats the most unreliable piece of battery monitoring software available, most people on this forum would agree, i suggest you use iStat.

    It's normal for it to fluctuate. The reading in the System Profiler often varies, just go by that.

    Also, calibration will keep it a little more level with the monitoring.

    I like the menubar version the best, but it doesn't include a battery monitor.
