Milwaukee 18V to DeWalt 18V Battery Adapter

Use your Milwaukee M18 batteries on DeWalt 18V Ni-Cd cordless tools, without buying into a second battery platform. Both run at 18V, so the adapter changes the fitting and not the voltage. 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.

Why choose this adapter

• Your Milwaukee M18 battery and DeWalt 18V Ni-Cd tools run at the same voltage, so the adapter changes the fitting rather than converting anything.
• Injection-moulded ABS, not 3D printed — no layer lines to split under load.
• Solid copper terminals, so less of the current is lost as heat.
• 5 mm² internal wiring, rated for 40A continuous with 80A peak at 18VDC for up to 2 seconds, so a high-draw tool is not held back by the adapter.
• A USB port on the adapter, so the same battery charges a phone on site.
• Covered by a 12-month warranty from the day it arrives.

Milwaukee M18 and DeWalt 18V Ni-Cd compatibility

It works in one direction only: Milwaukee batteries powering DeWalt tools. For the opposite pairing, see adapters that run on DeWalt 18V Ni-Cd 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 DeWalt 18V Ni-Cd batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge Milwaukee or DeWalt 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.
