Breathed new life into Dyson
Battery on vacuum was dying and wouldn't last 5 minutes. Swapped out with this battery and now runs like new. Was easy to replace.

Battery was lasting long time and stronger. But the 1st one passed away 3 month usage, and then I purchased the 2nd one. The 2nd one was also dead after one-time charge.

Great replacement battery for a Dyson cordless vacuum cleaner
This battery was worth every penny. It is so much better than the battery that comes with it our Dyson. Now we don’t run out of charge. Our house is small so there was no reason for that. Now we are happy with our Dyson finally. But if you want a light, go order those little green lights that stick on to the side of your vacuum head. They’re rechargeable . They are pretty cheap and you can see all you’re vacuuming up. Now you don’t need to buy the most expensive model of Dyson. You’ve just upgraded it twice for very little. You’re welcome 😇

Great replacement.
My mom’s Dyson cordless vacuum stopped accepting a charge, I found this aftermarket battery replacement for a fraction of the cost of an original and it works perfectly.

Working Again!
Ahhh, my Dyson is working again. Hopefully, this battery will last 2-3 years. It's easy to install and cleans the whole house.
