JCB 18V 4.0Ah High Capacity E-TECH Li-Ion Battery for JCB 18V Tools

JCB 18V 4.0Ah High Capacity E-TECH Li-Ion Battery (JCB-18BLI-4HC)

Extended runtime in an ultra-compact form — the JCB 18V 4.0Ah High Capacity E-TECH Li-Ion Battery delivers double the capacity of the 2.0Ah version with only a marginally larger footprint. Up to 50% longer runtime makes it the ideal battery for tradespeople who need sustained power without the extra bulk. Fully compatible with all JCB 18V Cordless and Professional tools.

4.0Ah High-Capacity Runtime

With 4.0Ah capacity and up to 50% longer runtime than the 2.0Ah battery, this pack is built for sustained performance through demanding applications — fewer battery swaps, more work done.

Ultra-Compact Design

Despite doubling the amp-hour capacity, the 4.0Ah HC battery is only marginally larger than the 2.0Ah version, maintaining the compact profile that keeps tools balanced and comfortable in hand.

E-TECH Lithium-Ion Technology

Next-generation high-capacity lithium-ion cells with advanced power density and efficient cooling deliver consistent performance under heavy load, extending both tool and battery service life.
