Charge last longer

It works great on my robot vacuum

Made my old deebot work great again!

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 $!

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.

I have a Eufy 15C Max. After running it for over a year, it started shutting off before heading home to charge. I came to Amazon to find a cheaper replacement battery. I purchased this battery because it's advertised as a higher capacity than the factory Eufy battery. The battery powered the vacuum for a little while, but did not solve my issue with the vacuum turning off before heading home. The runtime was not any longer than the original battery. So, I figured my vacuum was a dud.That's when I bought a new Eufy G30 Edge to replace the old 15C. Now, my G30 started doing the same thing where it would shut off before heading home to charge. Thinking that there's no way I have the same issue with two Eufy vacuums, I decided to also try this battery in the newer vacuum. The battery has not been used very often, but it is 1.5 years old now. So, my expectations were low. With that said, it did not solve the problem with the G30. It only ran for 39 mins before powering off.Finally, I decided to buy the official Eufy battery. I found a two-pack on Amazon for a small amount more per battery than these random replacement batteries. Both vacuums are back to running for their normal runtime and return home for charging. DO NOT buy these random replacement batteries. They will not provide the longevity or runtime of the factory batteries. You're just throwing money away. Spend a little extra on the official batteries. They last longer and work better.

Works really good. Plug and play. Easy to install too.

I love my little Deboot robot vacuum cleaner. His name is Zoolander because can only turn left. I am against planned obsolescence and love that these replacement parts exist so I can continue to use the original product that I purchased, repair it, and not have to throw it out and purchase a new one.
