Makita 18V to RIDGID 18V Battery Adapter

This adapter lets you power RIDGID 18V cordless tools with the Makita 18V LXT batteries you already own. Voltage is not the obstacle here — both sides are 18V. The socket is, and that is what this solves. The molded ABS housing keeps it light and hard-wearing, and pure copper contacts keep current delivery steady. It is a cost-effective way to get more from the batteries you have, with no second charger to maintain.

Why choose this adapter

• Your Makita 18V LXT battery and RIDGID 18V 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.
• Covered by a 12-month warranty from the day it arrives.

Makita 18V LXT and RIDGID 18V compatibility

It works in one direction only: Makita batteries powering RIDGID tools. For the opposite pairing, see adapters that run on RIDGID 18V 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 RIDGID 18V batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge Makita or RIDGID 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.
