where can i get replacement batteries for a 14.4v hammer drill clm144hdsek

Phil Morgan, December 2009

'Performance Power' seems to be a B&Q own brand so I would suggest they are the only people to sell that brand, however I would bet they are made by a dedicated power tool manufacturer such as Bosch, Black & Decker, Makita etc so one of their batteries may work.
Failing that you could try ebay.
