Bosch Twin EXBA18V-40 18v Expert Battery 4.0ah

High power in most compact design
The EXBA18V-40 high-power Expert battery delivers up to 2000W maximum power for demanding applications (based on internal lab testing; instantaneous maximum power with a fully charged new battery) in the most compact design. It uses advanced tabless cell technology whereas conventional batteries come with multi-tab cells that use only two tabs as current paths. This creates a bottleneck that adds to the resistance of the battery. Tabless cell technology opens this bottleneck. Instead of only two current paths, it offers countless parallel current paths. The result: less resistance, less heat, impressive power and an outstanding energy density. With its reinforced new robust housing, excellent thermal management from COOLPACK 2.0 and tabless cell technology, the EXBA18V-40 has a long lifetime and is therefore ideal for professionals who rely on durability and performance.
The EXBA18V-40 has an extended charging temperature range from -10°C to +55°C battery temperature when used with the EXAL18V2-320 or the EXAL18V-160. It features a 5-LED indicator that displays state of charge, remaining capacity and defect risk detection. Compatible with the Bosch Professional 18V System and the multi-brand battery alliance AMPShare.
It can be fully charged in just 30 minutes with the EXAL18V2-320 or EXAL18V-160, and weighs only 605g.
