Bosch Expert PRO BLUE EXBA18V-40 18v Cordless Li-Ion Battery 4ah
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.

Battery AH Explained
The best way to describe battery amp hour is that this is effectively the size of your fuel tank, the more amp hours your battery has then the longer the battery will last between charges. More amp hours does not increase the power of a given tool.
Battery Voltage Explained
A tool with a higher voltage than another is a bit like choosing an engine in a car, the higher voltage will generally mean higher power & performance. As with cars though a bigger engine does not always translate to better performance so it is important to compare the specifications of tools at different voltages between different manufacturers.
