    I've never full drained the battery below "50%" 61 times so I don't know why it says I've had 61 cycles. I always leave my laptop attached to the AC adapter. Is 61 Cycles with 99% battery life good for a 5 month old laptop?

    well if it keeps up that pace for the rest of its life, your battery will last 41 years...

    it must've been touched by jesus or something.

    One cycle is not 100% battery drain at one time, more like 25% drain, charging, 35%, charging, 15% drain, charging, 25% drain, charging.

    25% + 35& + 15% + 25% are 100% --> one cycle.

    MRoogle has more than many^2 threads about those battery concerns.

    99% battery health after 61 cycles is quite good.

    thats really good. Mine is 16 cycles and 92%. I am just biding my time until I have to take it into Apple. Anyone care to state what the warranty is on the batteries.

    This is off-topic but I'm curious.

    How do I check these things?

    What? Your battery increased in capacity?!?

    Talk about absolutely blowing away the bathtub curve.
