14.4v 2600mAh Li-ion Rechargeable Replacement Battery Compatible with Ecovacs Deebot N79S, DN622, Eufy RoboVac 11, 11S,11S MAX, 30, 15C, 15T, 12, 35C

So far, everything has gone well. The light on our Deabot vacuum would flash red and beep four times. After reading through a number of forums, I discovered that one person suggested the battery could be the problem. So I went out and purchased this one. To remove the old vacuum and replace it, all you need is a screw on the bottom of the vacuum. It provided a solution to the issue. There will be no beeping any longer! We've had the new battery installed for about a week now, and so far everything is working fine.

I knew my Eufy Robovac wasn't running as long as it used to, but the run time decreased so gradually that I didn't notice until it was only running for 20 minutes at a time. The Robovac 11 (not the 11, I hear) is super easy to replace. Replacing the batter is as simple as unscrewing two screws. I ran the unit the next day after charging it overnight. I was surprised that I vacuumed for 1 hour and 45 minutes. When the vacuum was new, I'm not sure I got nearly as much use out of it. The vacuum had been behaving strangely as well, changing program modes at random and so on. This appears to have been resolved as well by the new battery.

I had forgotten how long the vacuum was supposed to run for. My old battery was only good for about 10 minutes at the end of its life. LOL. This will take at least an hour to complete.

My four-year-old Eufy Robovac 11 has regained his youth thanks to this little buddy. When charging, I got four beeps every now and then. That, I assume, was a sign that the battery was about to die. It only lasted 15 minutes at first. It will take 20 minutes. I inserted the new battery (which was simple to do) and left it to charge overnight. It took me 100 minutes to run it in the morning. So far, everything has gone well. I only had it for a day, so I can't comment on how long it will last. Plan on riding this vac as long as the batter is still alive. I'm hoping for a third. 4 years. Because my house isn't very big, I don't need it to run for very long. So far, 5 out of 5 stars, and highly recommended if your battery is the only problem.

Batteries were less readily available for him at the time, but I recently checked and discovered this battery was compatible, so I decided to give it a try to see if he would stop beeping every 5 or 6 seconds. Carlos charged up and now cleans like a beast; good price, simple installation; and, as far as I know, we get the same cleaning cycle time as when we bought him. In comparison to previous robo cleaner replacements, this was a good deal.

So far, everything has gone well! Our Tesvor was a year or two old, and after running 5 times a week, it would only last 20 minutes at a time, so I took a chance and bought this battery, even though it doesn't say it's compatible, it's the exact same battery that comes with stock. br>br>On the first use, it's already been running for an hour and is still working. The $25 investment in a new vacuum robot is well worth it.

Belle began to work for shorter and shorter periods of time after five or six years. I considered swapping her out for a younger model, but ultimately decided she deserved a heart transplant. I'd forgotten how energetic she used to be; she's a great asset, and Belle will be with me for many years to come.

This battery was not capable of sustaining a charge. I now know that it was probably because it came completely depleted, and deebots are infamous for charging 100% dead batteries. I bought another one from a competitor and had the same issue, but after several battery resets, I was able to get it to work.
