Power tool battery adapters enable people to swap different battery types for incompatible tools. As Milwaukee M12, M18, and MX FUEL lines are mostly available at hardware stores, your prior tools in the V18 Lithium-Ion line can become completely useless, as the new batteries don’t fit the old tools. Some choose to use Milwaukee battery adapters rather than buy an entirely new set of expensive M18 or MX FUEL power tools.
In addition to making older tools compatible with a new line of batteries, battery adapters also make lower-voltage tools work with higher-voltage batteries, thus generating more power for the tool. This can come in handy in cases of V8 tools, where the power output isn’t enough. In some cases, it can also make M12 tools compatible with M18 or MX FUEL batteries.
It is important to note that there are dangers associated with using battery adapters, as these tools are meant for specific voltages. Using a higher-voltage battery could overheat the tool, resulting in potential fires. It could also wear down the engine faster as the tool is rated for a specific voltage. Lastly, there’s a possibility that the battery adapter just won’t work for what you’re trying to do. That said, being able to buy a few $20 adapters is much cheaper than replacing all the power tools in your shed, so it may be worth trying, depending on your situation.
