V8 Battery Adapter for Dewalt 20V Lithium Battery Converted to Replace for Dyson V8 Battery, Works with Dyson V8 Series Animal Absolute Vacuum Cleaner(DW20V8 Adapter ONLY)

I wanted to update this review. After using this adapter for the past 5 months. I still think this is the most ingenious mod. It still works flawless and I have enough charge to vacuum my whole house. I have told all my friends. I have a good friend that just bought a new Dyson and has never even used the official battery because he ordered this product. Great job you amazing engineers! This was easy to install and works flawlessly. I am already in the Dewalt tool world and know how the batteries are great performers. I can vacuum my whole house on the high setting without changing the battery. Best mod ever!!!

Installation was easy and I have 2 fully charged batteries, but the Dyson vac only runs 5 seconds and then I have to remove and replace the battery like it is being reset. Same result with both batteries. Restarts and runs another 5 seconds. Any suggestions?

Fit and finish was great. My Dyson worked great on the standard/low power setting, as soon as I switched to high power the vacuum immediately shut off. Not sure if I’m the only one with this issue. I charged the battery overnight with the same result in the morning.

So I purchased this because I’m on my third oem battery replacement and I hate those battery that only last 2-3 min on full ballast and now I can use my 6ah battery and I can change it when the battery runs out and that’s like 20-30 min later I’m all done with vacuuming only down side no oem charging port but that’s minimal

The device installs quickly (three screws) however doesnt work. The device shows a green battery indicator (full battery) starts vacuum then shuts off after a few seconds, still showing green light. I have read other reviews and other people have had the same issue. Sure would have been nice if it had worked.

Wish I would have dug deeper into the reviews before purchasing. The adapter is easy to install, and fits the Dewalt batteries without issue (which is why it gets 2 stars). But it will not work if your vacuum is set the the Max Suction setting. It will only turn on for 1 second, led goes red, and immediately turns off. Works just fine if you use the lower High Suction setting, but without the ability to use the Max setting (even from time to time)... is a deal breaker for me. Thats the whole reason I bought a Dyson in the first place!!

Doesn’t work. Don’t buy.

Works most of the time, but is not reliable. When it works--super! Id you have Dewalt batteries give it a try.

Great adaptor that works

I have plenty of deWalt batteries. Together they can run 2+ hours. The first time I can finish vacuuming my entire house continuously. Also, I remove the battery whenever I dont use the cleaner. which is safe.
