Batteries are vital for doing any work away from a mains power source, making tasks in otherwise tricky places simple to complete. Our 18V ONE+™ range of batteries and chargers fit with over 200 other tools in the same system. Our lithium powered batteries have increased storage and a four stage fuel gauge which handily displays remaining power at 100%, 75%, 50% and 25% so you know when it's time to recharge.
