Many DIYers start with one brand of power tools, then eventually switch things up.Like initially buying Milwaukee or DeWALT, then moving to Ryobi's more affordable line.A common solution to having a mix of different tools, battery packs, and chargers is to buy a battery adapter.
And while some people use adapters just fine, you probably shouldn't use them on your Milwaukee battery packs, and here's why.I get it.Power tools and their companion battery packs are expensive.
If you have a bunch of Milwaukee batteries lying around, you might as well try to find an adapter and use them on DeWALT, Ryobi, or even on a Dyson vacuum, as we've seen on Reddit.But doing so is a big mistake, and it could kill your battery.Power tool battery lock-in The goal is to keep you coming back Close As you all know, when you buy a power tool and its battery, that one decision instantly locks you into their ecosystem.
Out of the box, you cannot mix and match tools and battery packs with other brands.And that's exactly why battery adapters are all over Amazon or are touted by someone on YouTube.I'm not here to debate whether they're safe for every brand, and I have mixed feelings about the idea, but one thing is certain: doing so with Milwaukee batteries is playing with fire.

Learn more about those cheap tool battery adapters.Posts 6 By Cory Gunther For example, your Milwaukee M18 battery only works with M18 tools; you can't use it with any other brand, or even Milwaukee's M12 tools, for that matter.For many, this becomes a pretty big problem.
Ryobi's 18V ONE+ battery packs can power over 350+ different tools.It's a big reason people stick to one brand, not just for convenience, but because starting over is expensive.And if you do start over, you'll be tempted to buy one of those battery adapters on Amazon or eBay, but I'd think twice about that decision.
Don't use adapters with your Milwaukee battery pack It's easier than you think to ruin the battery Close I'm sure you've seen a YouTuber or someone on TikTok talking about how great these adapters are and how they can mix and match all their tools.And sure, it can be somewhat safe if you get a high-quality adapter, use it sparingly, and use specific tools or brands, but Milwaukee isn't one of them.The most important battery specs Milwaukee doesn't put on the box or the battery are the cell type and size, and the low-voltage protection system in place.
As for voltage protection, brands like Ryobi and Makita feature an internal battery management system (BMS) that cuts power entirely when the voltage drops too low, and the battery is about to run out of juice.This protects your expensive battery packs.However, Milwaukee products do the complete opposite.
Each Milwaukee tool has all the electronic control boards and management systems, and while communicating with the battery, the power tool is in charge of low-voltage cutoff.If you use a Milwaukee battery adapter to power an off-brand tool, no communication takes place, and you can easily run your battery down to zero.This can and will permanently damage, or even completely ruin, that expensive battery pack.
Related The battery spec Ryobi and Milwaukee don't put on the box (and why it's a big deal) You have to know what you're looking for.Posts 1 By Cory Gunther Voltage protection is extremely important when it comes to our cordless power tools.Every modern tool brand uses chips or electronic micro-controllers in both the tool and the battery to communicate with each other.
This ensures the proper voltage, ideal power output, stable performance, and keeps track of heat.When a tool is overused or the battery gets too low, the system shuts off to protect both the tool and battery.None of that happens if your Milwaukee battery is attached to an adapter and snapped into a tool from a different brand.
The battery doesn't have a built-in BMS system.It won't manage heat during big jobs, either, and heat can also degrade your battery.A few things to keep in mind In closing, there are certainly people who successfully use Milwaukee battery packs with tools from other brands.
I'm not saying you can't, I'm just saying it's a bad idea.Genuine Milwaukee batteries feature RedLink Intelligence for communication to monitor heat, overload, and low voltage.Adapters generally pass only raw positive and negative current.
If you are going to use an adapter, never let your Milwaukee M12 or M18 battery pack run completely out of power.Stop once there are only 1–2 bars on the battery indicator, well before it runs to zero, and never charge your battery with an adapter.Always use a genuine battery and charger.
