Ryobi 36V vs 40V Batteries in Australia: Are They the Same and What Fits?

Quick answer: Ryobi 36V products in Australia and products described as 40V in some overseas markets can relate to a similar nominal/max-voltage platform, but labels alone do not guarantee compatibility. Match the exact tool, battery interface, charger and product listing.

Why both numbers appear

Battery platforms may be marketed using nominal voltage in one region and maximum charged voltage in another. This explains some 36V/40V naming, but connector geometry and electronics still need to match.

Compatibility checklist

• Record the tool, battery and charger model numbers.
• Compare the connector rails and latch.
• Confirm the exact listing includes your model.
• Never substitute an 18V ONE+ battery.
• Use a charger designed for the platform.
