Bosch ProCORE18V Li-ion Batteries feature a new generation of cell technology delivering the same performance as standard batteries in an optimised size and weight. The battery also features COOLPACK 2.0 technology for superior heat dissipation from the inside to the outside of the battery. As heat can damage the cells, this COOLPACK 2.0 technology provides an impressive 135% longer lifetime than standard batteries, enabling it to perform for longer work periods. Compatible with all tools and chargers of the Bosch Professional 18V System and the AMPShare Alliance.
