Upgraded 4000mAh N79 14.4V Battery for Eufy RoboVac 11 11S 30 15C 25C 35C Robot Vacuum Cleaner for Ecovacs Deebot N79 N79S Deebot 500 600 DN622, Goovi F007C D380 Robot Vacuum Cleaner Battery

There was a eufo robo vac left in the closet of our house and the lights would flash but it wouldn’t run. I found this battery on Amazon and decided to take the gamble. Voila, the vacuum works great — it ran for nearly an hour (once charged) and with good results. I had never even heard of the brand before but thanks to Amazon search I was able to find the right one.

This battery is an upgrade to the one it replaced - Perfect fit. Wires are a tad longer making it easier to install / uninstall

Works as advertised. Good product.

Perfect fit and upgrade to our dead OEM battery. Almost doubled the running time from the stock battery. Feels like the vac has more power to it as well.

I received the vacuum this battery goes to from someone that never opened the box. I tried charging the battery and it would not charge. I ordered this replacement battery and swapped the out. I would have chose 5 stars if the battery came charged. It took about 5 hours to charge the battery, but it works great.

My robot vacuum disappeared under a bed, in the corner or a room. I could not reach it, so I left it there for a year. When I finally retrieved it, the battery was so dead, it would not charge. I was going to throw out the entire vacuum, but then I realized I could just replace the battery! This battery was easy to install, and charges perfectly! Great value!

So far so good. Battery came charged. Easy to replace. Two screws on bottom of unit, snap old battery out and new one in.
