Keenstone 14.4V 3200mAh Replacement Battery for 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

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.

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.

This was the perfect replacement battery. Now my Eufy has tons of life! I was under the impression that the battery could not be replaced. I was wrong! It was easy to do and so much cheaper than a new vacuum clraner!

Works perfectly for its purpose. My parents are a fan!

My Eufy 30C was showing the signs of its battery not holding a charge and this brought it back to life. Mine is pretty old, and pretty dumb (by today’s standards), but still gets the job done in my apartment so I wanted to give it a new lease on life before I needed to upgrade. This was relatively inexpensive and easy to install. I have no illusions that it may only last a couple years and I’m ok with that. Have no complaints so far. Recycle your old batteries, don’t throw them in the trash!

Working great in my eufy floor sweeper

Works good with my eufy 25c. Run time is about an hour

Battery worked for a couple of weeks. Now vacuum sits on charger with a mx reading of 79% batter power then dies the moment it tries to run. Do not recommend this battery at all.

I needed a new battery for my iRobit. This gas not been easy to find until I found this! It fits perfect and works perfectly. It lasts long enough to clean my whole main floor!

Fast replacement for robot vacuum

Bought this battery to dismantle it and use cells as replacements in a larger battery pack It was important for the bigger battery pack's balance that ALL cells be of the same capacity rating, i.e. 2600mAh I searched Amazon for those and the only affordable & quick way to get such cells was buying a smaller battery pack containing them Well, it was NOT a pleasant surprise to see the specifications of the cells after dismantling the purchased battery pack: they were NOT rated 2600mAh, but rather 2000mAh; see attached proof picture Also I click the hyperlink to report incorrect information and nothing happens I'll follow this up, Amazon
