    I'm in need of buying a new battery for my '09 Macbook Pro. Oddly, the original battery that came with the laptop has been physically expanding. If I laid it down on a flat table, you'd notice that the middle of the battery budges out a bit.

    Any who, I was looking around and I found this NuPower battery. Has anyone tried these and is it any good? Or should I just order the OEM one from Apple for $130?

    Based on the problems people have reported with 3rd party batteries, I wouldn't trust or recommend any battery that didn't come from Apple.

    I agree.

    You might see if Apple will exchange it - some folks here have reported that Apple has exchanged bulging batteries.

    i went into the apple store to exchange a battery, and the replacement one was barely better than the old battery. so i called apple support, and had them overnight a battery replacement. much better. the first battery was 97% after 4 days, the new battery shipped from apple is still at 102% after 8 weeks. i think the batteries at apple are newer and better.

    Not all batteries have the same health at time of shipment. It's perfectly normal for battery health to fluctuate up and down over time, even within the first few days. There's nothing wrong with such a battery. This should answer most, if not all, of your battery questions:

    interesting, it was down to 79% after a few more days, which is why apple exchanged it. i think there was something wrong with it, but maybe it would have recovered.

    If it drops below 80% before 1000 cycles, it is likely defective, as indicated in the "BATTERY LIFESPAN" section of the Battery FAQ. Any variation above 80%, especially less than 10% variation, is quite normal.
