Worked great in my robot vac. Easy to swap out, too. Let it charge several hours before trying it.

My robot vacuum has been a loyal companion for over 6 years—a true trooper. With the advancements in newer robot vacuums, I was intrigued. After researching and watching countless videos online, I discovered that the newer models, despite their mapping capabilities, clean rooms in similar timeframes. Instead of investing in a new vacuum, I decided to spend $20 on a replacement 2600mAh battery for my trusty robot vacuum. And wow, what a game-changer! It's like a new lease of life for my reliable cleaning buddy. This battery has breathed new vitality into my vacuum. It performs remarkably well, giving my old robot the power it needs to keep up with newer models. The $20 investment has paid off in spades, extending the life of my beloved robot vacuum. Overall, this replacement battery has been a fantastic purchase. It's revitalized my aging robot vacuum, making it as efficient as the newer models. Definitely a great battery upgrade for anyone looking to breathe new life into their trusty cleaning assistant!

Holds charge very well. Very satisfied

This battery lasts about one year in my remote vacuum. I buy this same battery every year because it is reliable and long lasting.

Update!!!! it is now 8/10/25 and I found out it wasnt the battery at all. Eufy was beeping 4 times which I thought was battery. Apparently you have to look and see if the red light on top is solid or blinking. My light was a solid red light, no blinking, which means it is the brush roller, not the battery. Who Knew? I watched a video on youtube showing how to clean the roller and the key is spraying a wd40 type spray in the little slots that the brush roller sits in because they get stiff and get hair them. Worked perfectly. I havent had Eufy stop since doing that so it was NOT this battery. The battery is fine. First review > I received this replacement battery on June 22nd and it already is starting to die. I dont use Amazon at all anymore because of this. Everything I get is a knock-off or Subpar. We used to get Carhart jeans, and workpants, Teva Sandals, etc. off Amazon. Pants were falling apart, shoes were not well made. This issue with many other items as well. After some research, I learned that I wasnt buying from Carhart and Teva, etc. I was actually getting cheap knockoffs from foreign companys. I have had to go on the actual site and buy, even if it is a little bit higher in price. At least Im getting the correct quality from the correct company!! I have a Eufy robot vac, which I love. After 2 yrs the battery started to fade, which is normal. I couldnt find a replacement battery anywhere except for Amazon and believe me, I looked. As per usual, I put it in my Eufy robovac and it has been 1 month and its already doing exactly what it was doing with the first battery. I try to research these companies to see if they are legit but they are buried behind so many names and addresses you cant hardly find them. When you do, it is always some bogus company with no true address or number. I cant find anything on Amazon anymore that is worth buying. Im off to find a battery anywhere else. Buyer beware.

This battery fit my Eufy Robovac perfectly. The vac is running like it did when it was brand new! I'm impressed with what a new battery can do.

Works good

this works with my Coredy Robot
