Makita 18V LXT and Bauer 20V compatibility
It works in one direction only: Makita batteries powering Bauer tools. For the opposite pairing, see adapters that run on Bauer 20V batteries.
Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the Makita 18V LXT platform and that your tool takes Bauer 20V batteries.
Important charging and safety information
This adapter is for powering cordless tools and nothing else. It cannot charge Makita or Bauer 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 Makita 18V LXT battery.
