Great replacement for Eufy robovac
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.

Quick, easy and affordable
Awesome battery. The Eufy I had was almost 5 years old and was running dead after 30 min. This battery was quick and easy to install and now we're getting full clean cycles again.

Battery life
Battery life is mentioned 2 plus hours after charge, it only works 1 hour and 4 minutes. Otherwise it works fine. Recharge time it takes about 3 hours.

It Restored Full Functionality
Our Eufy 11S had lost a lot of duration already when it suddenly dropped off a cliff. It would work for 5 minutes and just stop dead. The battery pack was easy to replace and restored full functionality and seems to run as long as new. I can recommend this one. It was easy to replace: Put it on its back and turn it off. Use the included screwdriver to remove the two small screws and lift the cover. I had to use the edge of a steak knife because there wasn't enough gap to use a thumb nail. Lift the battery out by the tapes provided on the old battery and unclip the connector to release the connection. (Push down with your finger nail to lift the tiny lock off the hook on the side and slide apart; it's easy) Re-connect the new battery pack and place it into the unit stowing the wires in the same way as the originals. Replace cover and screws, turn the power switch back on and place it on the charger until it has fully charged. That's it.

Excellent replacement for OEM
Replaced the battery in my RoboVac 35c, been installed for 3 months and performance has been the same as OEM. No issues at all!

Higher current than original, which is actually unhelpful
Fits and works fine. But the stronger current means it can wedge into places it used to bounce off, so it gets stuck more often.

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.

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.
