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)

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!!

Definitely not good for the battery. Shorts out after a week.

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.

Works intermittently. Same battery different battery clean filter dirty filter runs perfect one time then the next runs for 4-6 seconds and you have to wait 10 seconds for the vacuum to work again. Pass

I have multiple DeWalt batteries that I use everyday while at work. The largest battery that I have provided just a few seconds more than what the original Dyson is capable of. Any other battery would instantly shut the vacuum off if I try to use max suction. I received a replacement and had the same results. The issue isnt with my batteries... I can go days with constant use using my power tools and with no immediate need to recharge.

Tried multiple batteries - no luck. Inconsistent or pulsing suction. Skip it.

I have 2aH and 5aH batteries and this adapter fits both and allows extended run-time on my V8. It works on Max Suction or normal suction. I have not tried my 60V DeWalt batteries. Good buy if youre already invested in the DeWalt system.

I had the exact same problem as other users where the 20V 2ah battery didnt work longer than 10-20sec. I installed my 20v/60v 5ah battery and it worked fantastic. I assume a 20V with larger amp hour would work, but I only have an order small capacity 20V battery.

I bought this because the original battery would not last 10 minutes and I already had plenty of DeWalt batteries for my power tools. Installed easily and works but the handle gets really hot after about 15 minutes of use. I wear gloves to make it bearable but afraid the plastic may melt one day.

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.
