POWTREE Upgraded 3000mAh 14.4v NIMH Battery N79

Absolutely fantastic upgrade! My Eufy robot vacuum was struggling to finish even a small cleaning run, but after installing this replacement battery, it’s like the thing is brand new again. The installation was quick and painless, and the improvement was immediate. The runtime is outstanding—my vacuum now cleans the entire house without slowing down, and it docks with plenty of power left. It charges reliably, holds a strong charge, and has completely restored the performance I missed. For the price, this battery is an incredible value and an easy fix that brings your robot right back to life. Highly recommend it to anyone whose Eufy is starting to show its age. This battery makes a night-and-day difference!

Old model. Battery died. Easy to replace (Once I looked up on YouTube to be sure) and it works.

The battery works great, holds a long charge, no worries.

75 mins max runtime instead of the OEM’s 90 minutes. My robovac does not auto return to charge station with this new battery! Other than these two issues, this battery worked well for the $!

Works great, direct fit. now the robot floor sucker sucks the floor dirt up for much longer

I've been using this battery for about 2 months in my eufy BoostIQ RoboVac 11S MAX - it runs for about 20 minutes before heading home, and it doesn't make it home half the time before the battery dies. Either I've gotten a bad battery, or these batteries are poor quality.

Great fit & replacement for original battery. Brought new life to my old Deebot. Connector matches perfectly with existing plug. No issues!

When the original battery would no longer allow the robot to run for more than 15 mins on a charge, the search began for a replacement. I found this battery here on Amazon that had good reviews, noticed the watt-hours were higher than the original, and the price was decent so I gave it a shot. The battery arrived too slow (as all Prime items do now if you don't live in a metropolis, but that's a point for another day), but once it arrived I immediately installed it into our trust Deebot. The installation was mostly quite easy, though the package size of the battery is definitely a bit larger than the original battery, so the foam on the back of the battery hatch cover has to be compressed much more than with the original battery, causing a slightly bulge in the cover. So far this hasn't been a functional concern, but something to be aware of. With that being said, the increased capacity over the original is great, as the robot runs for close to 90 mins on primarily hardwood floors before it starts looking for the charger. I've only had the unit for just over a month so I can't comment to the longevity of the battery yet. So far I'm happy overall, and would buy again.

Just plugs in and works well.

No lo recomiendo. Aunque dice que tiene una vida extendida, solo llegó al año. La compré como remplazo de la batería original de mi RoboVac Eufy 11s, que me duró 5 años y está batería solo soportó unas 50 recargas, ya que no uso diariamente la robovac, sino una vez a la semana. No volveré a comprarla
