18V Battery platform

Ryobi ONE+

The platform most clearly built for home use: lots of tools, sensible prices and, according to Ryobi, batteries that fit even its oldest machines. Not built for heavy trade use.

Which batteries fit and which don’t

  • Ryobi says every ONE+ battery fits every ONE+ tool, old and new.
  • The 36V (MAX POWER) and small USB ranges are separate systems.
  • ONE+ HP isn’t a battery: it’s a series of tools that use the same batteries.

What people like most

  • Price and value for money
  • A huge home-and-garden ecosystem on one battery
  • Light, easy-to-use tools

What people criticise most

  • Finish and durability below the trade brands
  • Doesn’t cope well with sustained heavy use
  • Power-hungry tools (circular saw, grinder) need big batteries

I summarise opinions that come up again and again in forums and reviews, linked in the sources. I haven’t tested these tools in person.

Who it’s for

Good fit: Anyone starting out with cordless tools at home who wants to keep adding, including in the garden.

Not a good fit: Site trades, or anyone cutting and drilling all day.

Tool counts are the ones each manufacturer publishes and they change often. I checked them on 5 November 2026.
