Best Buy is recalling 5,100 replacement batteries for the Apple MacBook due to a fire risk.

The U.S. Consumer Product Safety Commission said Wednesday that there have been 13 reports that the battery caught fire. One consumer suffered a serious burn on the leg.

Best Buy Co. is voluntarily recalling both black and white ATG lithium-ion replacement batteries for the notebook computers. The batteries were sold online or shipped to customers through its Geek Squad services from September of 2008 through June of 2012 for about $50.

Best Buy said it is contacting customers to ask them to return the batteries for replacement or for a Best Buy gift card. Company spokesman Jeff Shelman noted that Best Buy is only one of many retailers that may have sold the batteries.

The model number “MC-MBOOK13B” is on the label of the black battery and “MC-BOOK13W” is on the label of the white battery. The ATG logo is on both.

Best Buy had mistakenly announced that the recall affects batteries for the Apple MacBook Pro, which has an unpainted aluminum case.
