Perfect 1:1 replacement for a stock OEM Dyson battery. Kit is excellent value.
Battery works great. Came pre-charged and slotted easily into a Dyson V6 Motorhead stick vacuum. For the price, compared to just buying a sole battery, this kit with a battery, replacement screws (with the right screwdriver you need to remove the old ones and replace the new ones), a cleaning brush, and two filters is a clearly superior value. Too soon to comment on the battery's longevity compared to the OEM battery, but I'm sure I'll get a few years out of this one. I'll update the review if it fails prematurely.

great product with great price!
This replacement battery brought my Dyson V8 back to life with noticeably stronger suction. Installation was quick and easy. The 6500mAh capacity gives me much longer cleaning sessions without needing a recharge. It holds power consistently, even when tackling carpets and pet hair. Charging is fast, and the battery doesn’t overheat or make noise. Feels just as reliable as the original, if not better. Overall, it’s a hassle-free upgrade that makes vacuuming smoother and more efficient. I will buy again!

So far so good!
The battery on my Dyson V6 trigger stopped holding a charge, so I bought this battery replacement which is more affordable than buying straight from Dyson. It fits perfectly and was easy to change out. I used the original screws instead of the provided screws because the provided ones seemed a little harder to screw in. The vacuum is working like brand new again -cheaper than buying a new vacuum!! It also came with 2 replacement filters, a tiny cleaning brush, screwdriver, and replacement screws.

I've been an Amazon customer for 15 years and I this is the first negative review I've ever written.
I've been an Amazon customer for 15 years and I think this is the first negative review I've ever written. That's how disappointed I am. I bought this item and received a clearly used battery in a box by itself with no screws, no product box, no nothing. I figured it was a product that another customer returned. That wasn't a dealbreaker for me as long as the product worked. I spent 15 minutes unscrewing the old battery off my vaccum and installing this one. Then I waited a couple hours for it to charge. The blue light would only come on for a split second as I plugged it in and I realized after waiting that this product is defective and won't hold a charge. I'm disappointed because now I have to unscrew everything again and exchange it for a new product. So I start the return process and order a new product. The new product arrives the next day and it is also an OBVIOUSLY USED PRODUCT THAT WAS RETURNED BY ANOTHER CUSTOMER. Their return label was still in the box. I bought a NEW product, not a used one. But TWICE I was given a defective used product. And the worst part is that I can't just drop this product off at UPS or Kohls. I have to manually print out a shipping label and provide by own box. Extra work to fix this sellers poor customer service. What a joke. I bought a 3rd replacement from another seller that works great. Do not recommend this one.

Runs well. Installation guide poor
The installation instructions are minimal. Enough for someone used to doing household repairs, they are enough. But I am not good at repairs and I had to make more effort than I wanted to figure out the process. There is a Phillips screwdriver included with my purchase, but when I had someone else help me with the installation, he found it too small. We used a slightly larger screwdriver. Not sure if that was necessary. The screw on the original battery was very tight and we needed to use pliers to unscrew and remove it. PROS: A new filter and cleaning brush were included. A PhillIps screwdriver was included (it may have been a perfect tool if the screw in the original battery had not been so tight). The battery was pre-charged and could be used as soon as installed. (I have only used it once, so don't know about how long it runs or how long it will be usable. But right now, it works well. CON: instructions about removal of old battery (no information about this) and installation of new battery were too brief for someone not used to doing this type of repair.

Highly recommend
My Dyson had become unreliable. Battery life was short, sometimes non existent even after charging. It was the original battery so it was time to consider a new one. This was a perfect match, easy to install and has worked great. Wish I would have replaced it sooner. Included filters were an excellent addition.

Appears to be a great replacement for the Dyson original battery
It only took two screws to replace the old battery and put in a new one, perfect fit. They thoughtfully provided 4 extra screws and even included a couple of brand new filters. My original Dyson battery has lasted for years. However, when I put it into the "turbo" mode, it would only last seconds before turning off. The first thing I tried with this new battery, even before I charged it, was the turbo mode. I ran it for minutes, much longer than the OEM battery.. The next test was to make sure it didn't get too hot in the charger. I didn't detect any heat while it was charging. It was fully charged the next morning and completely cool. This battery has almost double the capacity of the previous battery and that battery provided more than enough time. I'm particularly happy that I can now use the turbo mode for a long period of time. That really kicks the motor into high gear and provides an awesome amount of suction for such a small device. Time Will tell how well this battery lasts. It does come with the one-year warranty, but it was a small investment compared to the cost of replacing the Dyson.

A Breath of New Life for My Dyson V6 I recently purchased the Keenstone Replacement Battery 4600mAh for my Dyson V6, and I'm incredibly impressed. This battery has completely revitalized my vacuum cleaner, giving it a second lease on life. The battery fits perfectly into my V6, and the charging process is quick and efficient. Once fully charged, it provides ample suction power for both regular cleaning tasks and deeper cleaning sessions. The included pre-filters are a bonus and have significantly improved the overall performance of my vacuum. One of the standout features is the battery's long-lasting runtime. I can now clean my entire home on a single charge without worrying about running out of power. It's been a game-changer for me, as I no longer have to constantly switch between the vacuum and the charger. I highly recommend this Keenstone replacement battery to anyone looking to restore their Dyson V6's performance. It's a reliable and affordable option that has exceeded my expectations.

Ho acquistato questa batteria per il mio Dyson DC62 e sono rimasto molto soddisfatto. Si è rivelata perfettamente compatibile, facile da installare e subito pronta all’uso. Tiene bene la carica anche dopo diversi cicli e ha una durata più che soddisfacente, paragonabile (se non superiore) all’originale. Dopo mesi di utilizzo, continua a funzionare in modo costante e senza cali improvvisi di prestazioni. Considerando il prezzo, direi che il rapporto qualità-prezzo è davvero ottimo. Consigliata!
