The JCB Professional E-TECH 4.0Ah 18V Battery is a high-capacity lithium-ion battery engineered for strong, reliable performance across all JCB 18V cordless tools. Using improved cell technology, it delivers excellent power density and cooling efficiency for demanding on-site applications.

A 4-LED charge indicator provides instant power status to reduce downtime between tasks. Compatible with both the JCB Cordless Range and the JCB Professional Cordless Range, and suitable for fast and super-fast JCB chargers, this 4.0Ah E-TECH battery is the perfect upgrade for users who require a compact battery with significantly longer runtime and professional durability.
