Works very well in my Dyson V8 Animal, simple install.
I have a Dyson V8 and the battery has been starting to run down a lot sooner. I got this which has a higher capacity. It came with the battery along with replacement screws, a screw driver and replacement filters for the intake and exhaust. The install was very simple, remove the three screws and the battery comes out very easily. Put the new one in it's place and replace the screws. While it came with replacement screws, I just used the original ones. They were a little longer. There is one screw on the handle and two under the hatch at the bottom (see pics) The replacement battery looks very similar with a few minor differences that you can't see once it's installed. The new battery does have a little rubber bumper patch that sits flush at the bottom which is a nice touch. Although the battery has a higher capacity, it's not any larger. The battery feels well made very similar to the original one. The replacement filters seem just fine, similar to other aftermarket ones I've used in the past. I charged it overnight and used it until the battery was exhausted. It ran a very long time I didn't time it but it was almost twice as long if I had to guess. Normally I can do the steps and the upstairs and a little bit of the downstairs before the battery ran down, when it was new. With this replacement I did that but also the basement, basement stairs the whole downstairs and it was still going. I did all the corners and went over a few places because I wanted to run it all the way down before recharging. TLDNR? Easy to install, quality made and lasts a very long time, worth the price. update: 1/1/26 I've been using the new battery for a little while now. It's still working well and lasts a long time. The battery lasts pretty long. I tend to run out of steam before the battery does. I use to do most of the house on regular power and a few high traffic area spots on max. Now I can do the whole house then switch to MAX and do most of the house again. More often than not I finish before the battery is exhausted.

Excellent replacement battery—longer life than expected!
I bought this battery for my Dyson V6, and it works perfectly. It charges quickly and lasts much longer than my old battery, giving me plenty of time to clean without interruptions. The fit is perfect, and installation was very easy. Great value for the price. Highly recommend for anyone needing a replacement for their Dyson V6!

Good Replacement Battery!
I purchased this V8 replacement battery after having mixed experiences with a cheaper one before. The previous battery worked fine at first, but after about six months, the battery life dropped noticeably and couldn’t hold a charge for long. So far, this one has been a pleasant surprise. The package came very complete — not only the battery itself, but also all the necessary screws and even a screwdriver, which made installation quick and easy. The battery fits perfectly and works well with my Dyson V8. I’m hoping this battery will last longer than my previous replacement. Based on the build quality and thoughtful accessories included, it feels more reliable and well-made. I’m happy with the purchase so far.

Worth it!
Fit my stick Dyson perfectly. Very easy to replace the battery, just watch a video. I can vacuum my entire house with this, take about 45 minutes. With the original battery it would die out right when I was done, this one still has juice left amazingly. It also has better suction than it did originally. After I vacuum, I let it sit and cool about 10 minutes before I plug it back into the charger. The directions tell you to do that, rather be safe than sorry. We’ve had this 6 months or so now, no issues, it’s been great.

Great replacement battery at a fair price
Installed this into our 10 yr old v8. It works great, huge increase in run time of the vacuum Battery pack fits nice and easy to install. I would recommend this battery pack. Have used the vacuum for over three weeks now with no issues. Old battery would die after vacuuming 75% of the house. Now I can vacuum the whole house and have almost full bars.

It clicked in securely and worked seamlessly with the original charger. The runtime improvement is noticeable.

This battery was a great replacement for my Dyson V8. Installing it was easy and it fits perfectly with the original setup. I like that it works with the original Dyson charger, so there’s no need to buy a new adaptor. The 9000mAh capacity is the largest I could find on the market, and the run time has been really good so far. The battery indicator light is different from the original but it works just fine and does not affect performance. Suction is strong, and the extra filters are a nice bonus. Overall, it’s a solid upgrade and a great way to keep an older Dyson working like new.
