The Bosch CORE18V Compact Battery 2-Pack features two next-gen Lithium-ion batteries that each keep the power and runtime, while losing the weight.

The GBA18V40 single-layer battery features advancements in design to reduce resistance and increase efficiency, to improve the performance-to-weight ratio of tools used on the jobsite all day.

Engineered with 21700 cell technology, the battery matches the power from the original two-layer 4.0 Ah battery with improved performance per cell.
