Battery Adapter for Bosch to Milwaukee M18 18V Lithium-Ion Cordless Tool, Convert Bosch 18V Lithium Battery BAT609 BAT612 to Milwaukee 18-Volt Lithium Battery Converter (Not Universal)

My only 18 Volt Milwaukee tool is a leaf blower. I have two Milwaukee batteries but they just weren't enough to get the whole yard done. Since I already owned a number of Bosch 18 Volt batteries for my collection of Bosch hand tools, this was the perfect device to put the Bosch batteries to work blowing leaves. I still have to recharge the Bosch batteries in the Bosch charger, but then they run the Milwaukee blower perfectly.

Cheap way to fit my Bosch batteries I'm Milwaukee tools which is helpful

it works Bosch baterie hocks rite up to the Milwaukee tool and works

Whatever you do, do not buy this battery connector to go from Milwaukee battery Bosch. Hand tools, it will not work. The Milwaukee will fit into it, but it will not go on to the tool. Itself junk

I have a Milwaukee small blower and 3 Mikwaukee cordless battery powered routers, all of which are adapted to Bosch Core Batteries since they are the same 21700 cells as the Milwaukee XC M18 Red's. Most of my Tools are Bosch - Handheld Circular Saws, Small Grinders, Most of my Drills, Jobsite Radios, Lights. See I chose Bosch because the cost and because the batteries are so much cheaper. But then I found you could adapt the batteries and I was like....NO FRICKEN WAY!!! So now I have Milwaukee and Dewalt Tools mixed in and couldn't be happier. I honestly look to Milwaukee because they have some really good solid niche tools, well designed for the M18 series. And these battery adapters are the best ones I have!! I have thr Dewalt kind too, but the twin button side release is such a win, and this adapter feels more like an OEM Solution than some plastic printer rendition evolved into a subbed out chinese name your brand kimd of adapter (you guys know what i'm talking about). Haven't had any problems with them either. And I run the Bosch Core GBA18V120 12AH Batteries on the routers too for hours straight (see the picture I posted on my most recent project). If I get some likes on this review i'll try to make a video of adapting it. But the batteries slide in and out with ease, dismount from the tool easily too. Good quality, really is! And wait till the winter for Bosch to reduce their battery prices, camelcamelcamel if you question this (thought the tarrifs may have changed things).

Dropped it a few times, held up, this does not hook millwaukee batteries to the bosch drill, it hooks bosch batteries to the millwaukee drills

I'm on the Bosch platform but decided to go with a Milwaukee track saw. It came with a battery and charger, but I discovered that I wanted another battery. This allows me to use my Bosch batteries instead of investing in Milwaukee batteries for one tool. It is saving me money, and the Bosch batteries fit perfectly in the Milwaukee saw.

Works

Fit perfect, feels of good quality, would buy again.

Works as described. I was worried that there would be some circuitry the Milwaukee tool would require that this adapter didn’t have (like a digital handshake) and I believe there is something like that with the Milwaukee tools, but this adapter seems to have the work around in it. Clicked it to my Milwaukee tool and added my Bosch battery and it worked perfectly. Time will tell how it will hold up. It’s definitely not made from the same grade plastic as the original tools so we’ll see what happens if it gets dropped. The battery and the tool click into the adapter solid enough. Doesn’t feel any more loose than the original batteries.

Perfect fit. No issues at all. Very pleased since I have a lot of Bosch batteries.

Thought this would allow me to run my old Milwaukee V18 drills with my Bosch batteries, but they're for charging my batteries with the Milwaukee charger instead. Will keep looking for a solution. I don't want to get rid of my drills just because the batteries are crap. Might need to homebrew something with a 3D printer.
