Bosch GBA 18V 4.0Ah
The Bosch 18V 4.0Ah Battery delivers high-endurance performance for demanding construction and industrial applications. This lithium-ion power source utilizes advanced thermal management to ensure consistent power delivery under heavy loads. It is fully compatible with the entire Bosch Professional 18V System, allowing for seamless integration across various cordless tool platforms.
Built for the Job
This power unit serves as the backbone for high-draw cordless tools on the job site. Contractors and electricians rely on this specific capacity because it provides a superior balance between extended runtime and tool weight. It is engineered to withstand the rigors of heavy-duty drilling, grinding, and sawing where smaller 2.0Ah units would require frequent recharging. The internal housing protects the cells from vibration and impact damage common in workshop environments.
-
Powers heavy-duty SDS Plus rotary hammers for concrete drilling tasks.
-
Provides sustained energy for 115mm and 125mm angle grinders.
-
Optimizes runtime for circular saws and reciprocating saws on timber.
Product Highlights
