Replacement Battery for Eufy RoboVac 11, 11S, 30, 30C, 15C, 15T, 12, 35C, 15C MAX, for Ecovacs Deebot N79S, 500, N79, DN622, for Tesvor X500 Robot Vacuum Cleaners 14.4V 3000mAh

This generic replacement battery works perfectly with my Eufy RoboVac. Installation was a bit tricky due to the awkward positioning of the battery compartment, but that’s more about the design of the vacuum itself—it would’ve been the same challenge with the original manufacturer’s battery. Once installed, it powered up right away and has been running just like new. Great performance, great price, and no issues at all. Very happy with it!

Worked perfectly

After about two years, my Eufy robotic vacuum stopped working. The charging light was red and stayed on. The vacuum emitted a constant beeping noise. None of the troubleshooting solutions was applicable. I cleaned it well and replaced all parts. It still did not work. I purchased this replacement battery. It was easy to install. The vacuum works like new.

I never thought I would need a new battery because my vacuum charges but after two years it started lagging and turning off after a few minutes. I ordered this replacement battery and now it works like brand new! Easy to replace!

Had the battery replaced in about 10 minutes and once charged has been working like the original. Get about two hours for each run.

Exactly what my robot needed after not cleaning the entire house.

Purchased this battery based on advertised runtime. Very disappointed with the battery runtime which never exceeded 15-20 minutes. I put the battery through about 50 charge cycles, not once did I get the advertised 120 minutes. Will have to look for a different vendor/product.

My Eufy 11s Plus was failing to charge properly, so I bought the new battery to see if it would solve the issue so I didn't have to buy a new robovac. It worked great. Easy to install, and now my Eufy works like new again.
