Battery/charger set 2x EXBA18V-40 + GAL 12V/18V-80. The EXBA18V-40 high-performance battery delivers up to 2000 W maximum power for demanding applications (based on internal laboratory tests, immediate maximum power with a fully charged, new battery) in an extremely compact design. It is based on advanced "tabless" cell technology, whereas conventional batteries have "multi-tab" cells that use only two tabs for power conduction. This leads to a bottleneck that increases the resistance of the battery. "Tabless" cell technology eliminates this bottleneck. Instead of just two current paths, it offers countless parallel current paths. The result: lower resistance, less heat, impressive performance and outstanding energy density. With its new reinforced, robust housing, excellent thermal management through Coolpack 2.0 and "tabless" cell technology, the EXBA18V-40 offers a long service life and is therefore ideal for professionals who require durability and high performance. Simple and practical: The GAL 12V/18V-80 Professional is a fast dual-voltage charger for all 12V and 18V batteries from Bosch Professional. Thanks to the high charging current of 8 A, an 18V/4.0Ah battery can be fully charged in 38 minutes. This charger reduces downtime with its intelligent Active Air Cooling 3.0 by cooling the battery before, during and after charging. This compact charger is extremely practical to use with its bay-in-bay solution. The EXBA18V-40 has a 5-LED display for the charge status with remaining capacity and defect risk detection. The EXBA18V-40 and the GAL 12V/18V-80 charger are both compatible with the Bosch Professional 18V system and the AMPShare multi-brand battery alliance. In addition, the GAL 12V/18V-80 charger is also compatible with the Bosch Professional 12V system. The EXBA18V-40 weighs just 605 g. The GAL 12V/18V-80 offers simple wall mounting and two LED indicators for the charge status.
