This 2 Pack features two Bosch CORE18V® 4 Ah Advanced Power Batteries, each a compact battery delivering power in a lightweight solution.
You can get the power and lose the weight.
The GBA18V40 delivers high power in a compact size for medium-duty to standard applications, such as drilling into concrete, metal, and wood; metal grinding; cutting; and even light-duty chipping.
It delivers 2x the runtime and 60% more power compared to the BAT612 18V 2 Ah battery.
Designed with high-power Lithium-ion cells, the GBA18V40 features a single layer of enhanced 21700 cells for greater battery efficiency.
The cutting-edge battery design includes copper end plates, power rails, and a flexible circuit board for reduced resistance and increased efficiency.
This Advanced Power Battery has Bosch-exclusive CoolPack™ 2.0 technology, which cools the battery faster and helps provide a longer lifetime compared to Bosch 18V batteries without CoolPack™ 2.0.
Weighing only 1.10 Lbs., this compact battery provides performance comparable to much heavier batteries in a lightweight solution.
It is compatible with Bosch 18V tools and chargers and the AMPShare™ System.
A high-resolution charge-status indicator is also included.
