No cordless power tool is complete without a battery and charger. Available in a wide range of capacities, choose batteries with a 4Ah or 5Ah rating if you need consistent performance over a long period of time. 1.3Ah and 2Ah batteries are great for smaller, shorter tasks. A fast charger gets your battery ready for work quickly, but why not complete your toolkit with additional batteries you can charge another whilst you work? At B&Q we've got a wide range of batteries from trade and DIY brands so you can find the one you need.
