Ryobi, a household name for both professionals and DIY enthusiasts, has been at the forefront of producing reliable tools with equally dependable batteries.

But a question that often arises is: Can Ryobi batteries be used with tools from other brands, or can other brand batteries power Ryobi tools?


No, Ryobi batteries are not designed to fit other brands, as they are specifically designed for Ryobi tools. Using adapters can make them fit other tools, but this may void the warranty and is not recommended by the manufacturer.

This question isn’t just about convenience; it’s also about maximizing investments and ensuring seamless project execution.

Let’s look at battery compatibility, spotlighting Ryobi’s adaptability with other tool brands.

Ryobi Power Tools and Batteries

Ryobi is owned by Techtronics Industries or at least the USA division of Ryobi.  Ryobi is also an independent company with separate product lines in other parts of the world outside the United States.

Techtronics Industries (TTI) is a large manufacturing company based in Hong Kong. It owns the Milwaukee brand of power tools, among other brand names in other industries.  However,  Ryobi is a Japanese company that granted licensing rights concerning Ryobi cordless power tools to TTI.

While ownership is unrelated to the interchangeability with other brands of batteries for cordless power tools, it is mentioned because the ownership structure of various brands in cordless power tools can be confusing.  The one thing that is not, however, is the amount of money involved in the industry.

That money comes into play when discussing those power tools and the batteries that power them.  This will become clear as we go along.

Ryobi’s cordless power tools include drills, saws of all kinds, nailers, and so much more.  Each of them requires a battery, and the battery requires a charger for re-use.  Within the Ryobi line of power tools, though, the 18V battery requirements in the Ryobi ONE+ line are compatible with all.  

This certainly makes sense from both a manufacturing and a marketing standpoint – one battery that works with all of its power tools.  It is convenient for those who like the Ryobi line of tools and have brand loyalty.  They need one battery, maybe two, depending on the projects they tackle, and a charger, and that’s all.

Generally, it’s important to keep in mind a few things about cordless power tools, batteries, battery packs, and chargers:

  • Each manufacturer makes its own battery pack for its line of tools
  • These battery packs are made to fit well and tightly in the battery slots of their tools
  • There is no industry-wide general standard for battery pack sizes and battery slots on tools.

Lithium-ion batteries are a fairly recent technology in providing power to cordless tools.  They have replaced the previous technology, nickel-cadmium batteries.  They are rechargeable and include cells of various voltages from 1.2V to 3.6V, and are combined with each other to create batteries with voltage ratings up to 48V.

Ryobi and other power tool manufacturers then build their own battery packs to match their cordless power tools, so they fit well.  Beyond that, batteries are also in communication with the power tools’ motors as they work together, providing an efficient and effective tool.

Lithium-ion batteries, if properly cared for and stored, have a lifespan of between 3-5 years.  Properly cared for means not leaving them in the charger after they are fully charged, and proper storage has to do with not too hot or too cold.

Can Ryobi Batteries Be Used With Other Brand Power Tools?

Before we answer that question, let’s look at another group-owned set of brand names.  

Stanley Black & Decker owns, among other brand names, Stanley, Black & Decker, DEWALT, Craftsman, and Irwin lines of power tools.  Yet, each brand name and power tool line has its own branded battery pack and charger.  Notwithstanding each brand sharing some similarities in battery pack styles, there is no cross-brand compatibility.  

If such a large company with various brands under its corporate umbrella doesn’t make a single battery pack that is cross-brand compatible, it’s unrealistic to expect Ryobi’s battery packs will have any cross-brand compatibility, either.

That is actually the case.  The reasoning behind not only Ryobi’s lack of interchangeability and that of any other brand is simple – money.  Each of the various brands was independently making their own battery packs and charges before they were bought out by their parent company, and their tools were configured with their own battery slots into which the batteries fit.  

If there were a standard battery pack and charger, all brands would lose the sales of their own battery packs and be left with only their tools to sell.  With a lifespan of only 3 – 5 years, much shorter than the life of a well-cared for cordless power tool, companies know they will sell more batteries before the tools need to be replaced.

Economics drives this part of the power tool industry.  

Is There A Way To Make Power Tool Batteries Interchangeable?

Ryobi and DEWALT Batteries

Generally, the answer is no.  However, there are exceptions, and one of them has to do with Ryobi.

In an earlier article, we wrote about DEWALT batteries and Ryobi cordless power tools.  You’ll find that article here.

In the case of DEWALT batteries and Ryobi power tools, there is the Badaptor.  It’s a workaround that enables you to use DEWALT batteries with the Ryobi line of power tools, a battery adaptor that makes one compatible with the other.  It gives access to the use of the Ryobi line with just a single device and a DEWALT battery, saving money for a different battery, a different charger, and less storage.

There is a downside to using the Badaptor, though.  When you purchase a power tool, it comes with a warranty.  The same holds true for the battery pack and charger.  You are likely to find in the warranty language of your power tool that the warranty it comes with will be voided if you were to use an adapter or any modification to the battery pack, charger, or power tool that might allow the use of one.

You’ll save money with workarounds, perhaps, but at what cost?  It’s a value judgment to make – risk voiding the warranty for the sake of saving money on a new battery pack and charger.  

One other point worth mentioning is the incompatibility of Ryobi ONE+ battery packs and chargers, on the one hand, and older Ryobi power tools.  If they are old enough to carry and use the old nickel-cadmium technology and still usable as power tools, you can not mix the new technology batteries on the old technology chargers.

You would be able to use a nickel-cadmium battery on a new tool or a new lithium-ion battery in the old Ryobi tool.  Either one, actually, could be recharged with a new charger.  

The nickel-cadmium battery is an inferior technology, though, and a lithium-ion battery will hold its charge longer and last longer, and you may not want to mix and match things quite that much.  But it is possible.

For your future reference, if Ryobi is a brand you are considering, here’s a video that introduces you to the Ryobi ONE+ battery charger and its ease of use.

While the answer was a mostly short one, there are some exceptions.  Generally, though, Ryobi batteries are not interchangeable with other brands’ cordless power tools.  

We also don’t like the idea of workarounds or adapters because of the risk to a power tool’s warranty.  We pay for the warranty when we buy the tool, and we don’t like to waste money.  Perhaps you feel the same way.

Remember, though, that the Ryobi ONE+ 18V battery and battery charger are compatible with all of the 18V cordless power tools in the Ryobi ONE+ line of products.  This leads us to a recommendation:  pick a brand you really like and will suit your anticipated project needs, and stay with it in future purchases.  

You’ll need only one battery and charger, or perhaps two batteries and one charger, but either way, you will save money.

  1. I have a small operation that uses different brands of High-end tools. e.g. Milwaukee, porter cable, DeWalt etc. Some years ago, some of the new guys started buying Chicago tools. They were quite serviceable up to the present. The only problem i, no one sells the 18-volt batteries #45803. I think that some should suggest to Harbor freight to resume providing these batteries. The tools are still great.

  2. What about after market generic batteries sold on ebay and amazon? I’ve had very good experience with the Milwaukee look alikes, but bad results with half of the Ryobis. At 1/3 the price you think they’re a great deal, untill you have to use a die grinder to get them to fit into your tools.

    • LOL, yea, and I am pretty sure they void the warranty if you were to ever get caught. Probably extremely slim, but who knows.

  3. Well written, concise and plain speaking; answers most of my questions. I chose Ryobi years ago, mostly on a whim that I don’t remember, price or something and decided to stick with them for the reason you stated and will probably continue as I have only niggling issues with one tool that probably can be satisfied with an updated model.
