Description

Unrivaled Runtime and Corded Power for the Toughest Demands

Push the boundaries of cordless job site performance with the Bosch GBA18V120 CORE18V 12 Ah PROFACTOR Exclusive Battery. Engineered specifically to drive high-demand tools, this beast of a battery delivers equal power and at least 50% more runtime than the CORE18V 8 Ah Performance Battery. It features a triple-layer arrangement of enhanced 21700 lithium-ion cells, providing the massive energy reservoir needed for table saws, rotary hammers, and large angle grinders. By utilizing copper end plates and efficient power rails, the battery minimizes resistance, ensuring your BITURBO Brushless™ tools run cooler and longer under heavy load.

Built for longevity, the GBA18V120 incorporates Bosch’s exclusive CoolPack™ 2.0 technology, which manages heat buildup to cool the battery faster and extend its overall life compared to standard packs. Despite its massive capacity, it maintains a manageable weight of 3.04 lbs, offering a performance-to-weight ratio comparable to much heavier alternatives. Please Note: This battery is engineered exclusively for high-demand tools and is compatible only with Bosch PROFACTOR™ tools featuring BITURBO Brushless™ Technology; it is not compatible with standard Bosch non-PROFACTOR™ 18V tools.
