Works great! Replaced the battery of my Eufy 11s.

Easy direct replacement for the original battery. Can't say how many uses it will last, but the vacuum ran long enough to finish the room.

I recently purchased the AHJ Replacement Battery 14.4V for my older vacuum cleaner, and I’m pleasantly surprised by how well it performs. The battery came well-packaged, fully charged, and ready to install. Swapping it out with the old one was simple and only took a couple of minutes.Performance:The power output is solid, and it brought my vacuum back to life with noticeably improved suction and runtime. On a full charge, I get around 30–40 minutes of use, which is on par or better than the original battery. It charges reliably without overheating or making any noise.Build Quality:The battery casing feels sturdy and well-made, with no loose parts or cheap plastics. The connectors fit securely, and everything feels like it’s built to last.Compatibility:This AHJ 14.4V battery was a perfect match for my vacuum model (confirm compatibility before purchasing). It’s also a cost-effective alternative to name-brand replacements, without sacrificing performance.Overall:If you need a dependable replacement battery for a 14.4V device, the AHJ battery is a great choice. It restored full functionality to my vacuum at a fraction of the price of the OEM option. Highly recommended.

One day, my Eufy just stopped working... At first, I thought it was just lazy and didn't want to work. I tried several remedies, but yelling "you suck" at it didn't do anything, so I tried something different and ordered this battery. After installing the new battery and apologizing for calling it lazy, it started working as it did when it was new. I've had it a few months and though I feared the new battery may be evil and cause the Eufy to change personalities and attack me, it seems to either be patiently plotting the attack or it may not actually be evil. Check back - I'll lower my rating by a few stars if it does attack. BTW easy to install... it's a battery.

Worked perfectly. My eufy would stop running after 6-7 min even after charging for days. I searched possible remedies and someone suggested a new battery. I wasn’t even aware there was a battery. Put in the new battery and it’s running like new.

I bought the battery pack to replace the old one in my DEEBOT 661 robot vacuum. Although the vacuum isn't on the list of supported appliances, the battery is fully compatible with it. This is the second time I ordered the battery. The previous purchase lasted for more than two years, slightly longer than the original battery which came with the robot. I typically run the robot two or three times per week, each lasting around 200 minutes before recharging. Thus, the replacement battery matches the original one in capacity, performance, and charging cycle number. The price is also reasonably competitive. The item is a decent product well balanced between quality and cost.

Bought this battery middle of 2024. It stopped working in less than a year in use. Poor quality.

Perfect fit to my Asuna S1 vacuum. Even though that unit was not listed I compared dimensions and it worked
