Retailer Best Buy is recalling 5,100 third-party battery replacements for the black and white MacBooks, made by a company called ATG and sold through the retailer's Geek Squad service division or online between 2008 and mid-2012 due to the risk of overheating and fire. The US Product Safety Commission has collected 13 reports of incidents with the replacement batteries, including one where the buyer suffered a serious burn on their leg. The batteries are also sold through other retailers, but only Best Buy has initiated a recall at this point.
