No. Treat RYOBI 40V and 36V batteries as separate platforms. RYOBI’s compatibility guidance says tools and batteries are designed for specific voltage ratings, and its 40V product listing confirms compatibility with 40V products—not with 36V tools. Check the exact tool model and manual before buying or charging a battery.
What RYOBI’s compatibility guidance says
RYOBI Australia says batteries and tools designed for different voltage ratings are not interchangeable. Separately, RYOBI’s US listing for the 40V 4Ah Lithium High Performance EDGE Battery, model OP40406TA, states: “RYOBI 40V batteries are compatible with any RYOBI 40V product.” That is a 40V-to-40V compatibility statement; it does not establish compatibility with 36V products. RYOBI’s 40V battery listing and RYOBI Australia’s battery guidance support those platform-specific limits.
Why 36V and 40V labels do not prove a cross-fit
RYOBI uses a 36V MAX POWER label in UK materials and sells 40V products in the US. The available official pages do not provide a universal conversion chart or establish that every 36V and 40V product is electrically or mechanically identical. Regional naming, a shared brand, or a similar-looking battery is not evidence that it will fit or work in a particular tool. Follow the voltage and model information on the tool itself.

RYOBI UK describes its 36V MAX POWER charger as compatible with 36V MAX POWER batteries. That does not support using a 36V charger with a 40V battery, or the reverse. Use the charger specified for the battery and tool in the exact product manual. RYOBI UK’s battery and charger guidance identifies the 36V MAX POWER pairing.

How to check before buying or charging
- Read the tool’s rating label. Confirm its voltage rather than relying on memory, battery appearance, or the brand name.
- Record the exact tool model. Check the model’s official product page or manual for the supported battery platform.
- Match the battery and charger to that platform. A matching amp-hour (Ah) rating does not establish compatibility; verify the platform and exact model.
- Confirm any claimed cross-fit with RYOBI or the seller. Ask about the specific tool and battery models before purchase if a listing claims that a 36V and 40V battery can be used across platforms.
Which replacement should you choose?
If the tool is confirmed to be a RYOBI 40V model, OP40406TA is an example of a 40V battery. Verify that the specific regional listing, tool model, and required capacity match your needs; this example is not a recommendation for a 36V tool. For a 36V MAX POWER tool, use a battery and charger confirmed for that exact tool model in current regional documentation. The cited UK guidance describes the 36V MAX POWER pairing but does not identify a universal replacement battery model.
What is established—and what is not
The manufacturer guidance establishes platform-specific compatibility, not a universal 36V-to-40V cross-fit. RYOBI’s 2019 Nordic catalogue shows that the company marketed a 36V garden-tool platform in that region, but it is historical context, not current compatibility guidance. The current regional product and guidance pages cited above do not explain whether every product sold under the two labels is identical or provide a model-by-model cross-region equivalence chart. Check the manual for the particular tool rather than inferring compatibility from regional labels.
