Our unique patented 56V ARC Lithium™ technology is designed like no other battery. It’s why it performs like no other battery. The innovative arc shape helps to transfer heat away from every cell to stop overheating and maximise run times, and the Keep Cool™ Technology works to manage the heat transfer on every cell to keep the temperature lower for longer. Our 4.0Ah battery fits in any EGO Power+ tool, giving you flexibility depending on your usage. The recharge time from flat for this battery is from 80 minutes with a standard charger, or 30 minutes with our rapid charger, so you can get back on the move sooner.With zero emissions during use, our 56V ARC Lithium™ battery gives petrol-matching power but without the fuss and fumes. We’re one of the few equipment manufacturers who commit our research and development programme exclusively on battery powered equipment. Every year, we innovate to ensure our products are ahead of the curve when it comes to user health.
