## Description

The Bosch Expert PRO BLUE EXBA18V-40 is an 18V 4Ah cordless lithium-ion battery pack designed for professionals demanding high power in a compact, lightweight form. At the core of this battery is advanced tabless cell technology, which replaces the conventional two-tab current path with countless parallel current paths. This significantly reduces internal resistance and heat build-up, resulting in up to 2000W maximum power output and outstanding energy density — making it well suited to heavy-duty applications where consistent performance is critical. Durability is reinforced through a robust housing and Bosch's COOLPACK 2.0 thermal management system, extending the working life of the battery even under sustained professional use. The extended charging temperature range of -10°C to +55°C ensures reliable operation across a wide range of site conditions. Practicality is further enhanced by a 5-LED indicator displaying state of charge, remaining capacity, and defect risk detection. With a full charge achievable in just 30 minutes using compatible Bosch chargers, downtime on site is kept to a minimum. The EXBA18V-40 is fully compatible with the Bosch Professional 18V System and the multi-brand AMPShare battery alliance, making it a versatile investment for contractors already working within either ecosystem.
