18V One+ 4Ah Edge Tabless Battery

The next evolution in Batteries has arrived with the RYOBI 18V ONE+ 4Ah EDGE Lithium High Performance Tabless Battery. It harnesses cutting edge technology to get optimum performance from your RYOBI ONE+ products, delivering up to 160% more power and twice the runtime*. This EDGE Battery has one of the best power-to-weight ratios of any ONE+ model currently available**.

Previous generations of lithium-ion batteries have tabs on the battery cells, which can restrict power transfer. This next-generation EDGE battery design features tabless battery cells with minimal restriction of power delivery. All this free-flowing power ensures your tools can perform at their peaks for longer.

During demanding applications, excess heat can affect the performance of a standard tool battery. This EDGE Battery has a COOL-CORE PRO™ heat management system, which utilises laser welded cell straps and upgraded heat sinks to manage temperature and maximise the life of battery cells.

IntelliCell™ technology monitors and balances each battery cell to prevent overloading and deep discharge. This further enhances battery safety and longevity.

The high visibility LED fuel gauge makes it quick and simple to monitor how much runtime is left.

A durable overmould makes this EDGE Battery more robust and heavily resistant to bumps and knocks.

This EDGE Battery is a great option for high-draw tools including circular saws, grinders, hammer drills, mid to high torque impact wrenches and chainsaws. Use this EDGE Battery with your RYOBI HP™ tools for maximum performance.

The EDGE Battery’s size and weight also make it great for compact, high performance ONE+ tools*** designed for one-handed use including Compact Drill Drivers, Impact Drivers and Hammer Drills.
Available in-store and online from Bunnings Warehouse.
