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 need to apologize to the Comaony that sold me this product. For whatever reason, and let’s call it user error (but I honestly don’t know) I put the battery in the charger again and let it charge, again and I have had over 35-40 minutes of operation time. It works. As advertised.

i had to come back to this page to figure out how to swap the battery adapters. There are 3 screws total, 2 are hidden. Other than the setup, this thing is incredible!!!!

Unfortunately this product only works for low suction. As soon as you switch it to max suction the battery light flashes red and shuts off. I dont know about you, but the low suction on my Dyson isnt even worth it. Waste of time & money with this attachment.

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

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!!!

sent back didnt work well

This product was very simply to install. As far as working correctly no. This product only works in the normal speed for the vacuum. When I go to max it runs for two seconds and shuts off. I tried freshly fully charged dewalt battery and it continued to do the same thing. Would not recommend this product.

Just as bad as the original battery. Freak batter would be fully charged and not last long enough to clean the first floor

Adapter works great can use vacuum much longer now

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.
