Bosch Professional GBA 18V 4.0 Ah Lithium-ion Battery

The Bosch Professional GBA 18V 4.0Ah Li-Ion Battery Pack is a rechargeable power source for professional cordless tools. It delivers 18 V and 4.0 Ah in a lithium-ion format, offering up to twice the runtime of a standard 2.0 Ah pack under comparable conditions. The battery fits directly into the Bosch Professional 18 V System and works with tools from the AMPShare Alliance. It is designed for extended use in demanding professional applications.

A charger is not included and must be purchased separately. The battery is compatible with a wide range of Bosch Professional 18 V cordless power tools and chargers. The box contains a single unit, intended to add runtime capacity to an existing tool collection. Selling it as a standalone accessory avoids duplicating equipment for users already invested in the ecosystem, and it can also serve as a direct replacement for compatible equipment.
