Battery pack 4x EXBA18V-40 + 2x EXBA18V-80. The high-performance battery EXBA18V-40 delivers up to 2000 W maximum power for demanding applications (based on internal lab tests, instant maximum power with a fully charged, new battery) in an extremely compact design. The powerful battery EXBA18V-80 offers up to 120% more runtime for excellent continuous operation even in tough applications (compared to Professional GBA 18V 4.0Ah, internal lab test, grinding on soft steel with GWS 18V-15 S + flap disc, intervals of 30 seconds with 5 seconds breaks). Both batteries are based on advanced "Tabless" cell technology, while conventional batteries use "Multi-Tab" cells that only utilize two tabs for current conduction. This creates a bottleneck that increases the resistance of the battery. The "Tabless" cell technology eliminates this bottleneck. Instead of just two current paths, it offers countless parallel current paths. The result: lower resistance, less heat, extreme runtime, and maximum power. With its reinforced robust housing, excellent heat management with COOLPACK 2.0, and "Tabless" cell technology, the EXBA18V-80 offers a long lifespan and is therefore ideal for professionals who require durability and high performance. The EXBA18V-80 has an expanded charging temperature range of -10 °C to +55 °C battery temperature when used with EXAL18V2-320 or EXAL18V-160. It features a 5-LED display for charge status with remaining capacity and fault risk detection. Compatible with the Bosch Professional 18V system and the cross-brand AMPShare battery alliance. The EXBA18V-40 can be fully charged with the EXAL18V2-320 or EXAL18V-160 in just 30 minutes and weighs only 605 g. Fully charging the EXBA18V-80 takes 39 minutes, and its weight is 1.04 kg.
