The innovative design helps prevent overheating to avoid cut-out. Each cell is surrounded by our unique Keep Cool™ material that keeps cells at their optimum temperature for longer. In addition, the battery's Arc shape transfers heat away from the cells.

Unlike other brands where batteries are encased on the inside, our batteries fit onto the outside of our tools to stay cool. They’re protected from dust and moisture by a resin coating and a shock and vibration absorbing case.
