Short answer: RYOBI states that “Over 175 ONE+ Tools – All Work With Any RYOBI ONE+ 18V Battery.” That wording is unusually direct compared with the compatibility claims DeWalt and Milwaukee make on their own product pages, as covered in this site’s earlier platform guides. The practical payoff is a single 18V battery family that feeds a wide tool range, plus a charger ecosystem that still supports both modern lithium-ion and legacy Ni-Cd packs.
“All Work With Any RYOBI ONE+ 18V Battery” — what that actually covers
RYOBI’s own battery page puts the promise plainly: any ONE+ 18V battery should run any ONE+ tool. That is the core buying argument for the platform. If you own a single RYOBI ONE+ battery, RYOBI says it is interchangeable across the line.
Capacity choices follow the usual trade-offs. The 18V ONE+ High Performance 4.0Ah battery is rated by RYOBI for “up to 4X the runtime of standard lithium” and “up to 30% more power than standard lithium,” with an 80-minute charge time. It is positioned as the step-up option for users who want more runtime than the base lithium packs without moving to the largest capacity class.
How big is the ONE+ system, really? RYOBI’s own pages don’t agree
Tool-count claims on RYOBI’s own pages are inconsistent. The battery product pages checked both state “over 225 unique products.” The ONE+ collection page referenced in this site’s earlier RYOBI ONE+ platform guide states “over 300+ compatible products.” RYOBI does not reconcile those two numbers. The same kind of internal discrepancy has already been noted in this site’s DeWalt and Milwaukee guides, so the appropriate response is to report both figures and leave them side by side.
HP batteries and Brushless tools: a real exception worth knowing
The 18V ONE+ LITHIUM+ HP 6.0Ah battery is designed to pair with “over 100 tools from RYOBI’s 18V ONE+ lineup” through HP communication technology when used with Brushless tools. This is not a second platform total; it is a narrower subset defined by HP/Brushless pairing.
RYOBI also includes a specific limitation: “HP Performance does not apply to Brushless Lawn & Garden Products.” That is a named exception worth keeping in mind. If you are buying an HP battery specifically for the performance boost, lawn and garden brushless tools are excluded from that boost according to RYOBI.
A charger that spans two decades of battery chemistry
RYOBI states its batteries “recharge on any 18V ONE+ dual-chemistry charger.” The dual-chemistry part matters. The RYOBI 18V ONE+ 6-Port SUPERCHARGER accepts “18V Lithium-Ion or Ni-Cd” batteries, meaning it will charge current lithium-ion packs and older Ni-Cd packs alike. That is a real difference from the newer platforms covered in this site’s DeWalt and Milwaukee guides, which do not carry a Ni-Cd generation.
The reason is historical: the ONE+ platform itself dates back to 1996. Because the same battery mount has stayed in service across both chemistries, RYOBI’s charger lineup still bridges both.
The 6-Port SUPERCHARGER “charges up to six ONE+ batteries (one at a time) in as little as 30 minutes per battery.” That is sequential charging, not simultaneous parallel charging. It also has a “2 Amp USB output for charging phones and tablets,” and uses “IntelliPort technology to maximize battery life.”
What this guide does not claim
The “100 tools” HP figure and the “225 unique products” figure are different measurements and are not interchangeable. This guide does not estimate runtime for any specific tool beyond what RYOBI states. The 6-Port SUPERCHARGER charges batteries one at a time; it does not charge six batteries at once.
