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.

Better than the original
Great replacement and last longer than the original. Noticed improved performance and vacuum time last longer, even at Max speed. Battery gets warm, however the job gets done. I’m happy with my purchase

Great product
I was a little hesitant about buying an aftermarket battery for my Dyson, but I’m so glad I did. This battery works just as well as the original—if not better. The installation was quick and easy, and it fit perfectly without any issues. For the price, this is an excellent value compared to the name-brand replacement. It saved me a lot of money and extended the life of my vacuum.

Great battery. Extremely difficult to install (not because of the battery maker!)
This battery works and fits perfectly on my Dyson V10. I did want to give a word of warning. I don’t fault this maker for this but it’s still something you need to know. The screws that come out of the existing vacuum and the screws that have to go back in are ridiculously difficult. They strip. It takes so much muscle and pressure to screw them in. They do provide the special screwdriver, which should be helpful. But in my case, it wasn’t enough. I just simply wasn’t able to get the screws in all the way. However, it still works so I’m gonna call it a win and curse Dyson for making an impossible battery mount.

Restored my Dyson V10 back to original function
We previously bought a 6000mAh battery for our Dyson V10. The charge light ever only showed a half charge and the functionality quickly faded with a year. This 800mAh unit has our vac working like new, similar to the OEM battery, which is incredibly expensive.

Good choices
Easy process to replace. Holds charge well. Plug into battery seems just a rainy bit off center.

Prisvärt Batteri
Köpte detta batteri till min Dyson V6 då mitt original blinkade rött och ej gick att ladda efter ca 20 mån anv. Har endast provat detta en dag men är mer än nöjd, hoppas kapaciteten och hållbarheten är bra. + pris = ca hälften av ett original + passform + nytt filter ingick + snabb leverans - inget ännu

This battery has completely revitalized my V6
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.

Ottima batteria, dura nel tempo e mantiene la carica
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!
