Bosch expert starter set - 1 18v-40 battery + charger
The high-performance EXBA18V-40 battery delivers up to 2,000 W of heavy-duty peak power (based on internal lab testing; maximum instantaneous power when new and fully charged) in an extremely compact design. It uses advanced Tabless cell technology, unlike conventional batteries that contain cells with multiple tabs, only two of which act as current paths. This creates a limit that adds to the battery's resistance. Tabless cell technology overcomes this obstacle. It contains infinite parallel current paths instead of just two. The result: lower resistance, less heat buildup, astonishing power, and extraordinary energy density. Thanks to its new, durable and reinforced housing, excellent thermal management with COOLPACK 2.0, and Tabless cell technology, the EXBA18V-40 battery offers extended runtime, making it ideal for professionals who require durability and performance. Simple and practical: the GAL 12V/18V-80 Professional is a dual-voltage rapid charger for all Bosch Professional 12V and 18V batteries. Thanks to the 8A charging current, an 18V 4.0Ah battery can be fully charged in just 38 minutes. This charger reduces downtime thanks to the intelligent Active Air Cooling 3.0, which cools the battery before, during, and after charging. This compact charger is convenient to use thanks to its bay-in-bay solution.
Up to 2,000W maximum power for heavy duty applications.
Lower internal resistance for high performance and extraordinary energy density.
