Powilling Upgraded 3500mAh 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

Bought when an older robot vac wouldn't charge (five beeps when placed on the dock). Bought on a whim because it's so much cheaper than buying a whole vacuum again. It was a breeze to install. Let it charge overnight and now have a functioning robot vacuum again for less than 20 bucks. Plus it runs for a LONG time, so it's actually an upgrade from the factory original. Don't go with a pricey "name brand" replacement if this will suit you needs. It was affordable and works great!

Got this as a replacement for the previous battery in my eufy RoboVac 11S. It fit the battery holder and the connections were just right. Positives: So far, the battery is working well, charging, and giving me the same performance as the previous battery. Fits the Eufy Robo vac 11S Negatives: The battery life is unknown as I have only had it a short while. I got the Eufy 11S in 2018 and have had to put three batteries in it so far. I wish the other batteries would last longer. Maybe this one will? Overall, my grade is a A

My eufy robot vacuum died. I replaced the battery. That was the problem.

Easy to replace batteries They were constantly beeping and flashing red lights. I was lazy (…did not read troubleshooting section of robot vacuum manual). and just figured they were worn out after 3 years of use and a house full of animal hair. I took a chance and replaced batteries for all three DEEBOT vacuums….and now they are back to normal and working great. - yahoo !

Works perfect! Vacuum is good as new now. Runs for just over an hour again (was down to 10 minutes after 13 months.) The battery pack has the same basic markings as the original and slipped in and plugged in with no problem. (Old battery took a bit of force to unplug.) Before ordering, open the battery compartment of your unit and make sure it is the same shape. I see where people gave it a bad rating because it didn’t fit, when clearly they ordered the wrong one.

The 2 Batteries do NOT give the time as advertised! 3 Ah rating is incorrect/wrong and does not last as long as it should it almost gives the same run time as the original OEM battery of one and a half hours (Barley) 1.5 hours! I have multiple Bobovacs that are starting to need batteries after 2 years or more and don't think I will be buying your batteries if they will not perform as you advertise! Sorry! UPDATE!! since writing this review 3days ago, I've noticed the run time on these Batteries is getting worse!! Originally was getting almost 1.5 hours, today I noticed it has dropped to 1.15 hours. a loss of fifteen minutes is not good! Unless the seller responds to my complaint to them that I've made for replacements, I guess it will just be a loss and a lesson learned and not always a deal is good at a very low price!

Unit runs with new life. However, Mr. Deebot now just stops at the end of battery life. No hunting for the base anymore. Compared to our Eufy, this Deebot changes this battery in half the time that Eufy takes. Update 1 year later. The new battery and vac only lasted a couple months before becoming too much of an aggravation to pitch. Next time, we will buy OEM or just get a new vac.

We purchased a Deebot sweeper about 2 years ago & stopped working recently. My hubby suggested we get a new battery for it & low & behold, the sweeper worked perfectly again!
