Milwaukee 18V to Makita 10.8V CXT (Post Style) Battery Adapter

Use your Milwaukee M18 batteries on Makita 10.8V CXT cordless tools, without buying into a second battery platform. Your Milwaukee M18 battery is 18V and a Makita 10.8V CXT tool expects 10.8V. The converter holds the output at the tool’s level for as long as the battery lasts. The molded ABS housing keeps it light and hard-wearing, and pure copper contacts keep current delivery steady. It keeps one battery platform serving more tools, which costs less than buying into another.

Milwaukee M18 and Makita 10.8V CXT compatibility

It works in one direction only: Milwaukee batteries powering Makita tools. For the opposite pairing, see adapters that run on Makita 10.8V CXT batteries.

Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the Milwaukee M18 platform and that your tool takes Makita 10.8V CXT batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge Milwaukee or Makita batteries and must never be connected to a charger of any kind. Always take the battery out of the adapter before charging, and charge it on the original charger made for your Milwaukee M18 battery.
