Large capacity helps!
Fits the Dyson vacuum and works as of Sep 2025. It provides significant longer working time than the original battery.

Perfect generic replacement for Dyson
Super easy to swap out. My vacuum was dying within 20 minutes with the original battery, this has brought my vacuum back to over an hour of use.

Makes the dyson at least as good as new!
I so wish i had bought this a year earlier, rather than struggle with the vaccum dying after 10 minutes. I had no idea it was this cheap to make the dyson new again, and the filters and parts were a bonus. took under 3 minutes to replace the old battery, very very easy. love it, will now look for old dysons that dont charge and rehab them with these batteries to give to my kids. awesome!

Battery not working
Worked fine at first but after a few months, no matter how long you charge it, it does not hold any sort of capacity anymore.

Worked as hoped
I’m leaving 4 stars because I just can’t speak to long term use but right out of the box it fit with no issues and the included screwdriver was pretty handy.It charged up pretty quick and when tested on high it was way more powerful suction, so much so I had to pull only on certain low pile carpets. Also it lasted a full 7 minutes on high which unbelievable considering it never performed that well even when new and prior to this replacement the original battery lasted barely 20 seconds on high.I’ll update this review in a year and perhaps bump it up to 5 stars.

Could be better.
It was great for about 1 year. It actually started smoking when I plugged it in one day for charging. And was making a strange noise.
