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)

2 Things I have run into that may be a deal breaker for others. First it does not fit back into the wall storage charging station because the base where the battery used to be is now too large, this is without the Dewalt battery of course. Second the smaller 2 amp hour batteries do not work well with this. My guess is that as the battery charge lessens the voltage drops and the vacuum shuts off. I have not had a problem with the 4 or 6 amp hour batteries. It uses a surprising amount of battery when in high and using the brush attachments.

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?

Didn’t work well with my 3AMH desalt batteries. Would last maybe 5 seconds. Maybe with a larger battery it would be nice.

Amazing, it works perfectly. Used the screws from the original dyson battery instead of the supplied ones since the original were longer. There wasnt a ryobi attachment one sadly but purchased a dewalt slim 4ah and battery charger. Purchased dewalt battery from home depot - too many fraudulent ones on amazon. Dewalt website states that they do not sell on amazon. Dont throw the old dead battery in the trash. Take it to free electronics/hazard recycling or drop it off at work by your battery pickup area.

Had to spend $75 for new Dyson main body…worked well for those few times tho. Not happy

Perfect fit. Now I have 4 backup batteries for the vac. Have already used it twice as long as the original battery without a recharge. Outstanding!!!

Attached it to my Dyson v8…. blinked red and green lights and worked for a second then turned off. Doesn’t work.

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!!

It works well

Thank you random TikTok-er showing me that this existed! I can vacuum for dayssssssss now.
