21.6V V8 4.0Ah Battery Replace for V8 Li-ion Battery, 4000mAh Lithium ion Battery Compatible with SV10 V8 Animal, Absolute, Motorhead, Carbon Fiber, Fluffy Series Cordless Vacuum

Makes our V8 run like new again. Original battery had reduced battery life.

Worked great for a little while then stopped working after 5 months. The seller said it was still under warranty and that I would get a replacement through Amazon. That wan't true. Luckily Amazon worked with me and gave me a refund. I would not recommend buying this battery.

This battery was worth every penny. It is so much better than the battery that comes with it our Dyson. Now we don’t run out of charge. Our house is small so there was no reason for that. Now we are happy with our Dyson finally. But if you want a light, go order those little green lights that stick on to the side of your vacuum head. They’re rechargeable . They are pretty cheap and you can see all you’re vacuuming up. Now you don’t need to buy the most expensive model of Dyson. You’ve just upgraded it twice for very little. You’re welcome 😇

Battery on vacuum was dying and wouldn't last 5 minutes. Swapped out with this battery and now runs like new. Was easy to replace.

Ahhh, my Dyson is working again. Hopefully, this battery will last 2-3 years. It's easy to install and cleans the whole house.

Initially I was impressed with it because it gave me a much longer run time per charge of almost 25-30 minutes. The original 3+ year battery was not lasting more than 10 minutes per charge. However, in less than 5 months the battery is completely dead. Does not charge at all. I'm glad I kept the original battery and so I can switch back until I find a different brand. Waste of money with this short a life.

Great replacement battery but my only complaint is it doesn't hold a charge for an extremely long amount of time. On high you get maybe 20 minutes.

My mom’s Dyson cordless vacuum stopped accepting a charge, I found this aftermarket battery replacement for a fraction of the cost of an original and it works perfectly.

Worked well with Dyson V8

Fast delivery and the item i need, good service.

It never held a charge and was defective. Gladly Amazon refunded me the amount.

Well received and fit perfectly. So far works fine same like the original and hope the battery will last longer.
