The Bosch BAT612 2 Ah Standard Power Battery delivers the power you need at a light weight for general applications such as screwdriving and fastening. It provides outstanding runtime in a compact size. It delivers 25% more power and more than 30% runtime compared to previous generation BAT611 1.5 Ah battery. The BAT612 weighs only .75 Lbs., which is ideal for professionals who do a great deal of work overhead. It features CoolPack housing, which channels naturally occurring heat from within the inner core of the battery and dissipates it. This results in 100 percent more recharge life versus a battery without CoolPack. Built with a single layer of 18650 Lithium-ion cells, the battery is efficient and delivers significant power. It features single-cell monitoring for longer runtime. It features a charge-status indicator with high resolution for clear visibility. It has cold weather operation, working in temperatures down to -4° F. The battery is compatible with Bosch 18V tools, 18V chargers and a growing list of cordless products from AMPShare™ brands.
