Batteries & Chargers

The JCB 18V battery platform powers the full JCB cordless tool range. Choose from 2.0Ah, 3.0Ah, 4.0Ah and 5.0Ah lithium-ion batteries — all interchangeable across every JCB 18V tool. The 4.0Ah Pro high-capacity compact battery delivers maximum runtime in a smaller, lighter form factor. The JCB 18V dual charger keeps two batteries on charge simultaneously, eliminating downtime on site. The 4.5A fast charger and 9A Super Fast Charger (JCB-18FC-9, 20.5V DC output) cut downtime versus the standard 2.4A charger, restoring packs significantly faster. All batteries include charge-state indicator LEDs. The more batteries you run, the more time your tools stay in use.

Buying Guide

For trade use, run a minimum of two batteries per tool — one in the tool, one on charge. For a full day's work with a power-hungry tool like an angle grinder or circular saw, three batteries is a better starting point. Amp-hour (Ah) rating determines runtime: a 5.0Ah battery runs roughly 2.5 times longer than a 2.0Ah pack from the same charge. All JCB 18V batteries are cross-compatible, so any battery works in any JCB 18V tool. The 9A Super Fast Charger is worth the investment on sites where battery rotation is critical. Always store lithium-ion batteries at partial charge (40-60%) if not in use for extended periods.

Frequently Asked Questions

Are all JCB 18V batteries compatible with all JCB 18V tools?

Yes. All JCB 18V lithium-ion batteries — standard and Pro range — are fully interchangeable across the complete JCB 18V cordless tool lineup. This includes both JCB Pro brushless tools and standard JCB 18V tools.

What is the difference between 2.0Ah and 5.0Ah batteries?

The Ah (amp-hour) rating indicates energy capacity. A 5.0Ah battery stores 2.5 times more energy than a 2.0Ah battery, delivering proportionally longer runtime before needing a recharge. For heavy trade use, 5.0Ah batteries are recommended.

How fast does the JCB 9A Super Fast Charger charge a battery?

The JCB 9A Super Fast Charger charges a 5.0Ah battery in approximately 35 minutes and a 2.0Ah battery in around 15 minutes. It is the fastest charger in the JCB range and is recommended for trade use where battery downtime impacts productivity.
