Ryobi 18V ONE+ Battery Compatibility Guide: P102, P104, P108, RB18L50 and More

Quick answer: Match the 18V ONE+ platform, battery interface and charger chemistry. P102, P104, P108 and RB18L50 references help identify compatibility, but the exact tool and charger list should still be checked.

Capacity versus compatibility

Ah describes stored energy, not fitment. A higher-capacity pack may offer longer potential runtime but can be larger and heavier. Voltage, interface, electronics and charger suitability must match first.

Before ordering

• Confirm the tool is 18V ONE+.
• Record the original battery reference.
• Check charger chemistry and voltage.
• Consider weight as well as capacity.
• Do not confuse 18V with 36V/40V products.

FAQs

Does higher Ah make a battery more powerful?

Ah mainly indicates capacity. Tool output depends on the complete battery and tool system.

Can an 18V battery fit a 36V tool?

No. These are different voltage platforms.
