Ryobi 18V Battery
Looking for a Ryobi 18V battery? Every pack in this collection fits the full ONE+ platform — one battery across 175+ tools. Ryobi names its 18V packs two ways: classic P-series part numbers (P102, P107, P108) and regional RB18L-series codes (RB18L13, RB18L50). Our replacement packs cover both naming systems with grade-A cells, full protection circuitry, and drop-in slide connectors.

Frequently Asked Questions
What's the difference between P108 and RB18L50?
They are the same capacity class (4–5Ah) from Ryobi's different naming systems — P-numbers for North America, RB18L codes for other regions. Both fit every ONE+ tool; pick the code your charger documentation uses.
Can I charge a Ryobi 18V battery on any ONE+ charger?
Yes — all ONE+ chargers charge all ONE+ batteries. Fast chargers cut charge times roughly in half but generate more heat; standard chargers are gentler on long-term pack life.
How do I store Ryobi batteries between projects?
Store half-charged in a cool, dry place — not on the charger, not fully depleted. For winter storage, charge to about half every 2–3 months to keep cells healthy.
