Battery Adapter for Bosch 18V Lithium-Ion Cordless Tool, Compatible with Dewalt 20V Max/Milwakee M18 18V Li-ion Battery Convert to Bosch 18Volt Compact Lithium Batteries (Bare Adapter)

Works great for my use. I recommend it.

Works great in my blue bosch 18v tools using 20v dewalt batteries. No problems so far, it locks in very nicely.

Perfect stuff

Works good. It’s a little big but it has to be since the DeWalt battery is 20 volt. It needs to step down the voltage 2V which requires a few more parts.

I am able to use my Dewalt battery on my Bosch saw. Works as intended. Haven't ran the saw for extended periods but I would avoid pushing a tool or battery hard with these adapters.

Fits as it should

Does not work. P.O.S.

The adapter snaps into place and remains attached until release, but the fit in the Bosch tool is kind of sloppy. That doesn't affect its performance, which is excellent. The Milwaukee battery snaps in tightly to the adapter, until released. I originally thought that there might be a tool balance issue, but I noticed no difference between using my Bosch angle grinder with an original Bosch battery or with the adapter plus a Milwaukee battery. This adapter works and enables me to use Milwaukee batteries on all my Bosch tools.

Couldn't be happier. Arrived on time and works as expected! Works for the newest bosch lineup as well –it was very unclear as to whether or not it would be compatible, but as of Octovber 2025 - the newest bosch lineup accepts this connection, letting you use milwaukee 18V batteries with bosch tools. I thought it might be worth mentioning; it might not look like the right connection in the photos, but I think that's because it's missing the pins required for battery charging—which was listed as not supported.

Relación calidad -precio cumple bien su funcion..No es muy fte el plastico y los tornillos asi que no hay que manipularlo demasiado ..pero funciona bien..

Commander pour mettre mais batterie dewalt sur mon grinder bosch..fonctionne parfaitement
