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

Works Great and easy to replace!
This brought the vacuum back to life and I can now vacuum 80% of the house on a single charge. Great investment for the Dyson and easy to replace.

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.

Good value, working well
Great replacement for dead battery. Bonus filters included. Build quality is below OEM but so is the price. Time will tell if this battery lasts as long as the original.

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

Preis top - Leistung Flop!
Der Kauf war im Mai 2022, Rezension im Februar 2023: In den ersten Monaten war ich begeistert von dem Ersatzakku für unseren Dyson V6. Die Leistung war wesentlich stärker und länger (ca. 30 Minuten) als bei dem alten Originalakku. Der schaffte nach fünf Jahren nur noch knapp 15 Minuten und die Power war auch nicht mehr das Gelbe vom Ei. Seit zwei Wochen fängt der Akku an zu spinnen. Zuerst fing er gegen Ende der Akkuzeit an zu stottern. Der Sauger ging dann bei konstantem Druck auf den Schalter immer an und wieder aus und das im 2-Sekundentakt. Das macht er nun auch im voll geladenen Zustand. Heißt er saugt eigentlich gar nicht mehr, da dadurch kaum Schmutz durch das lange Rohr in den Schmutzauffangbehälter kommt. Damit ist die Saugwirkung gleich Null. Eine Lebensdauer von knapp neun Monaten ist selbst für den Preis nicht akzeptabel. Will man reklamieren landet man auf einer Seite in den USA. Also Null Chance auf Ersatz. Kann daher nur vom Kauf abraten. Ich wäre jetzt froh, wenn ich den alten Originalakku noch hätte!

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!
