Upgrade for Dyson V7+V8 Battery Adapter Replacement, for Makita 18V BL High Capacity Battery (Black) Work for Dyson V7/V8 Series Vacuum Cleaner (V7 V8 Common)

Although it did not come with “ how- to-install” instructions(causing a bit of doubt about the product), after figuring out how to remove the original Dyson battery installation was quick and easier than it originally seemed it would be. It works fine with my Makita batteries, and am very satisfied with this solution to being unable to obtain a replacement Dyson battery due to shipping restrictions ( Hawaiii). Thank you! MAKE SURE to verify your Dyson model number before ordering!

This works great - exactly what I was looking for since I already have Makita 5.0Ah 18V batteries and my Dyson's old battery had degraded to only lasting 5 minutes. Just an FYI that the adapter comes with zero instructions on how to uninstall the old battery and install the adapter, so I've included a couple of picts for other folks trying to figure out how this works. All you'll need is a size #0 Phillips screwdriver (bonus points if you have a right angle one as the screw on the handle was kind of tight to get to). Just undo the 3 screws (see picts). You have to open the trap door on the bottom to get at 2 of them. Pull down on the old battery to remove it from the inside of the handle. Load the adapter up into the handle and screw the 3 screws back in. Attach your Makita battery. Dispose of your old battery responsibly. Easy peasy.

This product works great. I'm not sure if it adjusts for voltage to address the fact that makita batteries are 18v while the dyson battery is 21v. Either way, the vacuum runs great with it and I can turbo clean the whole house. If the central or rear canister filter and dirty then turbo will shut off to protect the motor. Time to clean them or replace them.

Works great! Super convenient, but it no longer fits my wall mount. I tried to modify the mount and now it fits but falls right out when I let go. No big deal tho.

Excellent upgrade for my Dyson. Fit perfectly. Compatible with my Makita batteries, which give me far more runtime than the OEM battery. Great value if you have Makita batteries sitting around.

Here's something I didn't consider. this product makes it so this vacuum no longer fits in the charging base. Strike ONE! It hardly sits or rests on anything and is stable, so I had no idea what to do with it when I added this base and the battery. However, it worked fine the first few uses, but then it started cutting off immediately upon turning it on. Almost like it was overheating. When I requested support, I ended up in a chat where I was told that my makita battery was 18v and the Dyson vacuum is 21.6v therefore it was not meant to run this product. So this was his way of saying that I made a mistake and he was telling me I need to get the proper battery and referred me to a similar product that accepted a 20v DeWalt battery. Obviously, that wasn't a solution nor did it makes sense, but if he's right then this product shouldn't even be sold. Then I got another person in chat and was bumped to a phone call which eventually lead to them offering me a return with a restocking fee or an offer to exchange for the exact same product that may be flawed. I opted to pay the fee and challk it up as oppose to risk damaging my Makita battery or my Dyson vacuum with this product. Yet, it doesn't seem right that I'd only get a partial refund if this product is doomed to fail. If you are debating a used product likely listed in good or very good condition and it's shortly after I wrote this. Me have little faith. Likely, that is my product back on the shelf. Set it back down. Walk away. I'd be surprised if this review makes it through, but if it does, and somehow you dig it out from the bottom where they bury the other ones AND you are one of the very few who may read it, vote it up if you feel I'm being honest and if you think it may help others. This review was not written for any product promotion nor did I receive anything for free in exchange for my honest review... and I won't my breath for an invite any time soon haha.

This is working fine for me with my 5Ah Makita batteries. It definitely cuts off sooner than you would expect but makes sense given the voltage difference. The Makita battery is capable of running it until it gets down to two bars out of four then it quits. Still worth it to me since I have a ton of Makita batteries already and they are very easy to swap out and charge as needed.

Funciona perfecto y es muy fácil de adaptar y me dura mucho más
