Battery pack 6x GBA 18V 4.0Ah. The GBA 18V 4.0Ah Professional battery from Bosch's 18-volt class is designed for extended runtime. With its higher battery capacity, it allows for a 100% longer runtime compared to the 18V 2.0Ah model. Additionally, this model features COOLPACK 1.0 technology for better heat dissipation from the inside to the outside, as heat can damage the cells. The COOLPACK technology ensures a longer battery lifespan and enables longer operating times. All our batteries have been compatible with new and existing Bosch Professional tools within the same voltage class since 2008. The L-BOXX 136, with its specially designed robust insert, offers an improved storage and transport solution as part of the Bosch Mobility System. The optimized click mechanism of the L-BOXX allows for easy opening of stacked boxes for convenient handling. The comprehensive compatibility of the L-BOXX variants, tool inserts, and the Sortimo vehicle equipment system ensures absolute flexibility.
