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 provides a runtime that is 100% longer than the 18V 2.0Ah model. Additionally, this model features COOLPACK 1.0 technology for better heat dissipation from the battery, as heat can damage the cells. The COOLPACK technology ensures a longer battery lifespan and allows for 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. The package includes: 6x GBA 18V 4.0Ah battery, L-BOXX 136, 1/1 L-BOXX insert for starter sets.
