Ryobi Battery Interchangeability: A Comprehensive Guide

Ryobi’s One+ range of power tools and garden tools offers a convenient solution for users who desire a versatile and interchangeable battery system. This article delves into the compatibility aspects of Ryobi batteries, drawing upon information from reputable sources such as Direct Power Tools, Bunnings Workshop, and Amazon customer questions and answers.

Key Facts

  1. Ryobi One+ Range: The Ryobi One+ range includes a variety of power tools that use 18v Lithium-Ion batteries. These batteries have a “push in” style fitting that is completely interchangeable with the entire range of One+ tools. The system is also compatible with the older style “push in” One+ NiCad batteries.
  2. Battery Compatibility: The 18v and 36v batteries used in Ryobi tools are different and not interchangeable. Tools that are labeled as 18v can interchange their batteries with other 18v units, while 36v tools can interchange their batteries with other 36v tools. The 36v tools and batteries are exclusive to the gardening machines.
  3. Considerations: If you want to use the same battery system for both your lawnmower and drill, you may want to consider using the 18v Ryobi mowers instead of the 36v machines. This way, you can have all the same system of batteries.

Ryobi One+ Range: A Unified Battery System

The Ryobi One+ range comprises a wide selection of 18v power tools and garden tools that utilize Lithium-Ion batteries. These batteries feature a “push in” style fitting, ensuring complete interchangeability across the entire range of One+ tools. Additionally, the system is backward compatible with the older style “push in” One+ NiCad batteries, providing users with a seamless transition to the latest battery technology.

18v and 36v Battery Compatibility

Ryobi employs two distinct battery systems: 18v and 36v. These batteries are not interchangeable, meaning that tools labeled as 18v can only use 18v batteries, while 36v tools require 36v batteries. Notably, the 36v tools and batteries are exclusively designed for gardening machines, providing enhanced power and runtime for demanding tasks.

Considerations for Battery Selection

When selecting a Ryobi battery system, several factors warrant consideration. If the intended use involves both power tools and garden tools, opting for the 18v system may be advantageous. This allows for the utilization of the same battery across various tools, eliminating the need for multiple battery types. Conversely, if the primary focus is on gardening tasks, the 36v system offers superior power and runtime, making it ideal for larger gardens or more intensive applications.


Ryobi’s One+ range provides users with a flexible and interchangeable battery system, enabling the seamless operation of multiple tools with a single battery. The 18v and 36v battery systems cater to different needs, with the 18v system offering versatility and the 36v system providing enhanced power for gardening tasks. By carefully considering the intended use and battery requirements, users can select the optimal Ryobi battery system for their specific needs.
