Notes:
- 18V ONE+ System: All 18V ONE+ batteries (NiCad, Lithium, Lithium+, Lithium+ HP, and High Performance) have been compatible with all 18V ONE+ tools since 1996, except for the P194 (9Ah) which may not fit tools with watertight covers (e.g., Arctic Cove MBF018 misting fan).
- 40V System: 40V batteries are not interchangeable with 18V tools. Compatibility within the 40V range may vary (e.g., a 5Ah battery not working in a 2014 OLM36x40H mower). Always check specific tool compatibility.
- Chargers: 18V Lithium-ion batteries require dual-chemistry or lithium-specific chargers (e.g., P113, P117). NiCad chargers cannot charge lithium-ion batteries.
- Cross-Brand Compatibility: Ryobi batteries are not natively compatible with other brands (e.g., DeWalt, Milwaukee) but can be used with adapters (e.g., DeWalt/Milwaukee to Ryobi 18V adapter).
- HP Batteries: Lithium+ HP and High-Performance batteries (e.g., P191–P195, PBP003–PBP007) have extra contacts for better performance with brushless tools but are backward compatible.
- Aftermarket Batteries: Clone batteries (e.g., Powerextra, Masione) are compatible with 18V ONE+ tools and often cheaper, with mixed reviews on longevity.

Tips for Ensuring Compatibility
- Check Tool Specifications: Always refer to the tool’s manual or specifications to determine the appropriate battery system.
- Inspect Battery Labels: Ryobi batteries clearly indicate their system (e.g., 18V ONE+™, 36V MAX POWER).
- Consult Retailers or Ryobi Support: When in doubt, consult with authorized retailers or Ryobi’s customer support for guidance.

FAQ
What batteries are compatible with Ryobi tools?
Ryobi tools are primarily compatible with Ryobi-branded batteries from their specific battery platforms. The most common systems are:
- 18V ONE+™ – Works with all Ryobi 18V tools, both old and new.
- 40V MAX POWER – Used for higher-powered outdoor equipment like lawn mowers and chainsaws.
- 4V USB Lithium™ – Compatible only with specific compact tools designed for USB Lithium batteries.
Important: Batteries must be compatible with the tool’s platform. An 18V battery will not work in a 36V tool, and vice versa.
Can Ryobi batteries be used with other brands?
No, Ryobi batteries are not natively compatible with other brands like DeWalt, Makita, or Milwaukee. However, there are third-party adapters available online that allow you to use Ryobi batteries with tools from other brands (and vice versa), but:
- They may void warranties
- They can be unsafe if not used properly
- They may cause performance issues
It’s always recommended to stick to original battery-brand combinations for safety and optimal performance.

Do all Ryobi batteries fit the same charger?
Not all of them.
- All 18V ONE+™ lithium-ion batteries fit 18V Ryobi chargers.
- 36V batteries require their own 36V chargers.
- 4V USB Lithium™ batteries are charged via USB-C or specific charging docks, depending on the model.
You must use the charger designed for the specific battery voltage and type.
Can you put a Milwaukee battery on a Ryobi?
No, not directly. Ryobi and Milwaukee use different battery designs, terminals, and electronics. However, some users buy battery adapters that make this possible. These adapters:
- May cause performance issues
- Can be risky for your tools and battery health
- Are not officially supported by either brand
It’s not recommended for long-term or professional use.
Can I use any 18V battery in Ryobi?
Only if it’s a Ryobi 18V ONE+™ battery. Ryobi tools are only compatible with Ryobi 18V ONE+™ batteries, not 18V batteries from other brands like Makita or Bosch.
Even though the voltage might be the same (18V), the battery shape, terminals, and communication systems differ between brands.

Do Makita batteries work with Ryobi?
No, Makita batteries are not compatible with Ryobi tools. The battery and tool designs are different.
You would need a third-party adapter, but again, it’s not officially supported and may void warranties or create safety risks.
Is Ryobi battery universal?
Not entirely. Ryobi batteries are universal only within their respective platforms:
- All 18V ONE+™ batteries work with all 18V ONE+™ tools.
- All 40V batteries work with 40V tools.
- 4V batteries only work with 4V USB Lithium™ tools.
But you cannot use a 36V battery in an 18V tool, or vice versa. Also, Ryobi batteries do not work with other brands without special adapters.
8. Can I use Dewalt batteries in Ryobi tools?
No, DeWalt batteries are not compatible with Ryobi tools. They use different:
- Battery mounts
- Electrical connections
- Charging protocols
While adapters exist, they are unofficial and may lead to tool damage or poor performance.

Is 36V more powerful than 18V?
Yes, in general, 36V systems offer more power and longer run times compared to 18V. That’s why Ryobi uses 36V batteries for demanding outdoor tools like:
- Lawn mowers
- Chainsaws
- Leaf blowers
However, 36V tools and batteries are also larger and heavier, and not compatible with 18V tools.
