BiBiSi Replacement Battery for V7 21.6V 4000mAh V7 Battery Compatible with V7 Motorhead V7 Animal SV 11 V7 Absolute V7 Trigger V7 Fluffy V7 Mattress V7 HEPA V7 Car+Boat with Filters

Was easy to install, came with 2 filters and a tool kit!!

I am so glad I bought a new battery instead of buying a whole new vacuum!

I end up getting 5000 mAh battery, and it's amazing replacement for now. My previous replacement lasted about 18 months, let's see how long this will last.

It's been less than a year and the battery no longer charges. How do we get warranty replacement?

I made the mistake of buying a Chinese knock off replacement battery from a no-name company on another platform so had to step up to buy a battery with pretty good feedback on it that doesn't seem to last very long when I use it in my Dyson broomstick… Bummer!

Longer lasting between recharges than original factory installed battery. Accompanying instructions were easy to follow. Watch a video also. Removing the old battery may take a little effort if it’s screwed in tight. Definitely worth it.If your Dyson starts to lose its charge very quickly, then it’s time for a new battery.Only had got a few months so it’s too early to know how long this battery will last.

I was just about to give up on my old faithful vacuum until I came across this product. I am so glad I made the purchase it restored my baby to new. She's sucking hard like a hooker working for a $20! Well worth the cost.

This said it was compatible with the Dyson V7, but it would not work. I think something was defective internally as it appeared to be the same exact battery as the original.
