AHJ Replacement Battery 14.4V 2600mAh Compatible with Ecovacs Deebot N79S N79 DN622 500 & Eufy RoboVac 11 11S 11S MAX 11C 12 15C 15CMAX 15T 15MAX 25C 30C 30 35C G30 G32PRO G10 Hybrid

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.

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

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.

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.

The AHJ Replacement Battery for my imartine d900 was great until it died. It fit my vacuum perfectly and was easy to install, the battery life was shorter than expected. The Battery only lasted 2 years. Additionally, as it came to the end of its life the battery seemed to lose charge quickly. I was hoping for a better lifespan. But, The average lifespan of a robot vacuum cleaner battery is 2–5 years. I'm giving it 4 stars because it did last for 2 years and 2 months.

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

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

Item was accurately described, packaged well, and promptly delivered. Pleasure doing business!
