Bosch GBA 18V 5.0Ah Professional Lithium-ion Battery

The Bosch GBA 18V 5.0Ah Professional Li-ion Battery powers Bosch Professional 18V System and AMPShare alliance cordless tools. Rated at 18 V and 5.0 Ah, it provides up to 25 per cent more runtime than the 4.0 Ah variant. It suits professional construction, installation, and workshop tasks, supplying consistent power without trailing cables. Lithium-ion cells provide stable voltage throughout the discharge cycle.

Weighing 620 g, the battery keeps tools balanced and reduces wrist fatigue during overhead use. The COOLPACK 1.0 technology dissipates heat generated during use, supporting a longer service life under heavy workloads. An LED indicator shows the remaining charge before a task begins. The black and red exterior matches the rest of the compatible tool range.
