M18 12ah-13.5ah rebuild

This purchase is for a 12.0 to 13.5 extreme output battery rebuild. It is designed to enhance performance and extend overall power capacity. This is the highest demand battery I offer, an upgrade over the stock 12.0 and has more output current than my 15.0, making it the best for any tool in the m18 lineup. Please select if you are supplying the battery to rebuild or not.
