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.

good!
bought this replacement battery for my Dyson V10 (SV12) and it works great. It fits perfectly and was easy to install with the included screwdriver. Battery life is solid for daily cleaning, and the vacuum feels like new again. The two extra filters are a nice bonus. Great value for the price.

Good product
The battery works very well. My old Dyson V10 battery died after years and only works with low vacuum power. It works as before after replacing the battery. The package comes with filter replacements, a battery, and new scress and drivers. This is so considerate. The instruction for replacement is clear. The replacement only takes few minutes. I would recommend this product.

Check your charging cord first…it’s cheaper to replace anyway
My Dyson V8 quit holding charge as long, then stopped charging. Apparently this is common after 5 years of use, which happens to be how old mine is. I ordered this battery after trying everything google suggested. Installed easily. Still wouldn’t charge. I requested a replacement as I thought the first battery I ordered was bad. Second one came and I was still having the same issues. Turns out it was my charging cord that went bad 🫣. Anyway, battery works and fits my Dyson. The seller was kind enough to replace my first battery without incidence despite me being an idiot! Even comes with replacement filters, screws, and the appropriate screwdriver. Highly recommend!
