Hey I have a White 2009 13 inch MacBook(the one that still has the button). I recently bought a new replacement battery for it and I noticed even though the model and voltage are the same (A1185 10.8v) the watts are slightly diff. My old one says 55wh and my new one says 59wh. I just plugged the new one in and everything seems to work fine. I was just wondering if I could run into any problems using it. Thanks.

If it's a good quality battery, it should be OK. It's just the way the manufacturer has rated the battery that accounts for the slight difference in Watt Hours.
