Bosch ProCORE18V 4.0Ah Black Lithium-ion Battery

The Bosch ProCORE18V 4.0Ah Battery is a rechargeable lithium-ion pack for professional cordless power tools. It delivers 18 V at 4.0 Ah and fits tools and chargers within the Bosch Professional 18V System as well as compatible AMPShare alliance products. The compact format provides the output of a conventional 4.0 Ah battery in a lighter housing, reducing the overall weight of the tool during use. COOLPACK 2.0 technology manages cell temperature during demanding use, protecting the internal cells from heat-related degradation. This pack suits trade users who need to balance runtime against tool handling during extended jobs.

The black housing uses a compact slide-on connector for direct attachment to compatible tools without an adapter. A charger is not included, so a compatible Bosch Professional 18V or AMPShare charger must be sourced separately. This pack carries the ProCORE18V designation within the Bosch cordless system. It is intended for professional trade environments where tool balance and runtime both affect daily productivity. The unit ships in standard carton packaging for transport and storage.
