Milwaukee is a well-known brand in the power tool industry, and its lithium-ion batteries are popular among DIYers and professionals alike.
However, with so many different brands of power tools and batteries available, it can be confusing to know which batteries are compatible with each other.
We have done the research to provide you with the answers you need to know about Milwaukee batteries and their compatibility with other brands.
Understanding battery compatibility can save you time and money if you are a professional contractor or a DIY enthusiast.
So, let's dive into the world of Milwaukee batteries and see if they are interchangeable with other brands.
Can Milwaukee Batteries Fit Other Brand Tools Directly?
The answer to whether Milwaukee batteries are interchangeable with other brands of power tools is not straightforward and requires a qualified "yes."
Each brand has its specific battery design, meaning you cannot typically use a Milwaukee battery with a different tool.
For instance, although Bosch and Milwaukee 18v batteries might appear similar, they are constructed differently and cannot be used interchangeably.
That said, there are some exceptions to this general rule.
You can power a Ryobi 18v tool with an M18 battery using a "Milwaukee to Ryobi One+ 18v Battery Adaptor" (more on this later).
Furthermore, in certain situations, there's battery compatibility between Dewalt and Milwaukee batteries.
Makita 18v batteries can also be paired with Milwaukee 18v tools.
However, it's essential to emphasize that Milwaukee Fuel batteries are specially designed for brushless motor tools.
Using batteries with non-compatible tools can pose risks, potentially damaging both the battery and the tool.

What Are the Risks of Using Milwaukee Batteries with Non-Milwaukee Tools?
Using Milwaukee batteries with non-Milwaukee tools can be tempting, especially when you have various tools from different brands.
However, it is important to note that using Milwaukee batteries with non-Milwaukee tools can be risky.
Physical Incompatibility
The battery's shape, size, and connector may not fit snugly or securely in a non-Milwaukee tool.
A loose connection can cause inefficient power transfer or even accidental disconnections during operation.
Electrical Mismatches
Different tools have varying voltage and amperage requirements.
Using a battery that doesn't match the tool's specifications can result in poor performance or damage to either the tool or battery.
Overheating
Inappropriate electrical connections can cause overheating. This reduces the battery's lifespan and poses a risk of burns or fires.
Reduced Tool Performance
Even if the battery fits and powers up the tool, the tool may not operate at its peak performance. This can affect the quality of work and prolong tasks.
Warranty Voidance
Manufacturers often include clauses in their warranties that exclude damages resulting from the use of non-branded or incompatible accessories.
Using a Milwaukee battery with another brand's tool might void the warranty of either the battery or the tool.
Safety Concerns
Inconsistent power delivery or sudden shutdowns due to incompatibility can pose safety risks, especially with tools that have sharp or fast-moving parts.
Have Any Third-Party Manufacturers Created Adapters or Converters?
Yes, third-party manufacturers have recognized the demand for battery interchangeability.
They have developed adapters and converters to bridge the gap between brand tools and batteries.
For instance, as previously mentioned, the use of adapters like the "Milwaukee to Ryobi One+ 18v Battery Adaptor" allows the use of an M18 battery to power a Ryobi 18v tool.
Companies like Badaptor, Power Tools Adapters, and Lasica have created a niche by producing quality battery adapters catering to various tool and battery combinations.
However, Milwaukee does not endorse using third-party adapters or converters and may void your warranty.
If you do decide to use a third-party adapter or converter, be sure to do your research and choose a reputable manufacturer.
Look for reviews and testimonials from other users to ensure the product is safe and reliable.
The Other Way Around—Are There Battery Brands You Can Use with Milwaukee Power Tools?
As you may already know, power tool batteries are only compatible with the same brand, provided they have the same voltage, amps, and size/shape.
So, the general rule is that cross-brand compatibility does not exist between these power tools, as each brand has its own unique design, which fits well in its own tools.
While Milwaukee doesn't have many compatible brands, some other brands have compatible batteries.
For instance, while Dewalt batteries are reported to be compatible with some Milwaukee tools, although it's not a universal fit.
Meanwhile, craftsman, Black + Decker, Skil, Ridgid, Hart, Worx, Makita, Bosch, and Kobalt batteries were not compatible with Milwaukee tools.
What Are the Consumer Experiences and Reviews on the Topic?
Most users have had issues with compatibility.
The main issue seems to be that not all batteries are created equal, and some may not fit properly or provide the same power level as the original battery.
One user reported that they could use a Milwaukee M18 battery with a Ryobi tool, but it did not fit snugly and fell out during use.
Another user reported that they were able to use a Milwaukee M12 battery with a DeWalt tool but that the battery did not provide the same level of power.
If you're unsure about compatibility, it may be best to stick with batteries made of the same brand as your tool. This will ensure proper fit and performance.

Can I Interchange M12 and M18 Batteries?
Milwaukee's M12 and M18 batteries are not interchangeable.
The two batteries have different voltages and power, making it impossible to use an M12 battery on an M18 tool and vice versa.
Again, attempting to do so may lead to damage to both the battery and the tool.
Conclusion: To Interchange or Not?
The decision to interchange batteries comes down to personal preference and the specific needs of your woodworking shop.
If you're unsure whether it's worth it to try using non-Milwaukee batteries, it may be best to stick with Milwaukee-branded batteries.
Doing so will ensure the best possible performance and longevity for your power tools.
Remember, your power tools are an investment, and it's important to take care of them properly to ensure they last as long as possible.
By using only Milwaukee batteries or confirmed compatible adapters, you can help protect your investment.
