Hey guys! after finding a lot of information on this amazing forum I've for the fist time encountered a question on which I couldn't find the answer I'm having problem with my macbook battery which has only 29% capacity left so I'm looking for a replacement. While looking around on eBay and the official site, I found out that different batteries have different voltages. My current, the original, supply's ±12.5V but most of the eBay items supply only 10.8V. Would this be a problem? Thanks!
