RIDGID 18V to Bosch (Green) 18V Battery Adapter

Use your RIDGID 18V batteries on Bosch 18V PBA (Green) cordless tools, without buying into a second battery platform. Both platforms are rated 18V, so torque and speed on the Bosch 18V PBA (Green) tool stay where they should be. Built with a durable injection-molded ABS housing and pure copper contacts for steady current delivery. It removes the need to keep separate batteries for different platforms, which saves money and simplifies the workflow.

Why choose this adapter

• Your RIDGID 18V battery and Bosch 18V PBA (Green) 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.
• Made for the RIDGID 18V batteries sold at Home Depot, so the fit is the one you already own.
• Covered by a 12-month warranty from the day it arrives.

RIDGID 18V and Bosch 18V PBA (Green) compatibility

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

Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the RIDGID 18V platform and that your tool takes Bosch 18V PBA (Green) batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge RIDGID or Bosch 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 RIDGID 18V battery.
