Product description

Part of the ONE system this Ryobi 18V 4.0Ah battery is compatible with the full range of ONE tools for the home and garden, but is ideally suited to heavy-duty applications such as grinding, sanding and cutting. Ryobi Lithium technology provides more power, longer runtimes, and better durability than previous battery technologies, and unlike NiCad, does not suffer from 'memory effect'.

Featuring a tough pack design with built-in impact protection for long-term durability and a rubberised base. The 4-stage fuel gauge displays remaining power (100%, 75%, 50%, 25%) so you always know how much power you have left.

Lithium cells hold their charge over a prolonged period without losing power, ensuring batteries are always charged and ready to go. Battery sold separately.

We've been perfecting the ONE system for over 20 years. Our ONE batteries are compatible with all ONE tools. See individual tool listings for our battery size recommendations. Our tools are built to last and so is our warranty; 3-year warranty is included on all Ryobi ONE batteries.
