Hilti 22V to Makita 18V Battery Adapter

Use your Hilti 22V batteries on Makita 18V LXT cordless tools, without buying into a second battery platform. 22V in, 18V out: the converter brings it down to what a fully charged 18V battery reads, rather than passing the higher voltage through. Constructed from durable molded ABS with pure copper contacts, for a secure fit and dependable current transfer. It removes the need to keep separate batteries for different platforms, which saves money and simplifies the workflow.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge Hilti 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 Hilti 22V battery.
