Ryobi 18V ONE+ 4Ah EDGE Lithium High Performance Tabless Battery

The RYOBI 18V ONE+ 4Ah EDGE Lithium High Performance Tabless Battery delivers next-level performance for your RYOBI ONE+ tools - up to 160% more power and twice the runtime than a standard 2Ah battery*. This stripped-back design has one of the best power-to-weight ratios for any ONE+ battery currently available**. Components (tabs) in standard batteries, that can restrict power output and cause heat buildup, have been removed. This next-generation EDGE battery design features tabless cells that deliver free-flowing power with minimal restrictions. You get a Battery that enables your ONE+ tools to perform at their peaks for longer. A COOL-CORE PRO heat management system ensures this EDGE Battery stays cool under pressure. It reduces overheating that can cut off power to the tools when they are pushed hard. Laser welded cell straps and upgraded heat sinks manage temperature and maximise the life of the battery cells. IntelliCell technology has been incorporated to monitor and balance each battery cell. This technology works to prevent the cells from overloading and deep discharge, improving battery safety and longevity. The high visibility LED fuel gauge makes it simple to check how much runtime is left. A durable overmould makes this EDGE Battery robust and resistant to bumps and knocks. The EDGE Battery also unlocks the full potential of RYOBI HP tools. The additional power lets you harness their enhanced performance to get through tough jobs. The EDGE Battery’s size and weight make it a great power option for compact, high performance ONE+ tools*** including Drill Drivers, Impact Drivers and Hammer Drills. *When compared to the RYOBI 2Ah battery model RB1820C. Testing was performed by Techtronic Industries from 1 March 2024 to 30 October 2024. **As of January 2025. ***Not compatible with ONE+ products CBL1802, OLM1840BL, RCM1850 and RLM1840BLX6.
