I thought I will through the robo vacuum which currently worth 300AED and this battery is 90AED, i wouldn't have paid more for it. so acceptable. installed in my robot and for the last three days it is working fine no issues.

Life saver

My original battery was almost 3 years old, and was down to 20 minutes or less of runtime. This battery dropped in (clean all your contacts first - good electrical hygiene) and immediately started charging on the dock. I let it charge over night, and then ran the device and am pleased to report about 90 minutes of runtime. My device works like new again, for a very small investment.

So far so good. I ordered this battery a week ago because my old battery was about five years old and was the original. I don’t know why it didn’t dawn on me to look to see if I could purchase a replacement battery. I almost threw this unit away! Glad I didn’t. Install took less than a minute and put it on the charger and it works like a charm. Product arrived fast and was the most inexpensive option. Not sure how long this battery will last, but even if I get another year out of it, I’d be satisfied! Yeah, kit also came with a new bar and the little sweeping broom things. Made a five year old unit into a brand new machine.

This is not a Dyson-branded replacement battery but it works just fine in our Dyson stick. It's a bit tricky figuring out how to remove the expired original battery, but once beyond that, the new battery slips quickly in place.

Installed easily, fixed my red light alarm immediately

The battery was dying in my Eufy 11s robovac—the running time was getting shorter and shorter. Eufy customer service suggested trying a new battery so I did. This one was easy to install and worked perfectly.
