Replacement Battery Compatible with eufy RoboVac 11 11C 11S Plus 11S MAX 12 15C 15C MAX 15T 25C 30C G10 Hybrid G30 Edge R500 R450 & Ecovacs Deebot N79 N79S N95 DN622 661 | 14.4V 2600mAh

This replacement battery saved me a lot of money. Works perfectly for Eufy robovac! Easy to install and good battery life.

This was a direct replacement for the existing battery. After the initial charge the first run of the vacuum lasted two hours. Every subsequent charge and running the battery lasted an hour and 40 minutes exactly. Ran for six months without losing any charge capacity or run time. Vacuum died before battery did. I would recommend this battery.

Updated 5/27- user error, the battery works just fine for the eufy 30c. The power cord in my box for the vaccum was the wrong volts for the battery. Since this has been corrected the battery holds a long charge and works great. Highly Recommend.Original: I bought this battery as a replacement for my 30c. I even reset it with eufy customer service to accept the new battery. Every morning after it charges the app starts and it undoes and then has to restock saying the battery is dead. I have checked it not my docking station or connecting points . It’s possible I got a bad battery batch but dang I just wanna charge it and let it do its thing. Bummmed it isn’t charging to even use it.

I bought this battery because my robo vacuum would no longer turn on. The good news is that it works fine and was among the cheapest options available. The only thing I've noticed is that my robo vac will now turn on randomly. I suppose that could be a coincidence and not related to the battery, can't say for sure. So I just turn the vacuum off using the button on the bottom, a mild inconvenience but not a huge deal.

I had a robot vacuum that was not used for a while and eventually wouldn’t turn on. We almost tossed it but decided to try a battery replacement to see if that would solve the issue and it did! It fit my eufy robot vaccum perfect and allowed us to continue using the vaccum. It is extremely easy to replace and even comes with a little screw driver.

Good as original battery. I purchased for my EUFY G30. Vacuum as good as new. Easy to install.

I was a little leery by some of the reviews here but I figured it was an Amazon purchase and I could return if needed. I had my Eufy a bit over a year and used it daily. It started stopping while vacuuming; no beeping or anything. Just stopped and was "dead". I figured I would try battery and this price was decent compared to purchasing new vacuum. Now it runs well over an hour. Yay. Happy that is all it was.

Perfect replacement battery! Came with screwdriver and instructions. Charged up and robo vac working again.
