Why it makes sense

These batteries include multiple protection circuits against over-discharge, incorrect voltage, overload, short circuit and overheating, according to the manufacturer. That adds a degree of safety when using the pack with compatible Ryobi tools, and the cells are claimed to have no memory effect so you can charge whenever convenient. A minor caveat is that exact run time will depend on the tool and workload, so expect variation between drilling and lawn care tasks.

How to use it

Fit each battery into the tool until it clicks and follow the tool manufacturer’s guidance for charging. For best practice, store the batteries in a cool, dry place and avoid prolonged exposure to high temperatures. It’s a good idea to rotate batteries if you use tools frequently, to maintain usable charge across jobs. It’s a good fit if you need straightforward extended runtime without OEM pricing, and you’ll like it if you already own Ryobi One+ tools and want a spare pair for heavy projects.

What’s included

The pack contains two 5.5Ah replacement batteries compatible with Ryobi One+ and a user manual. A 12 month warranty is provided alongside customer support for queries.
