Direct fit and worked like new!
I recently purchased the Eufy replacement battery with a capacity of 4000mAh for my robot vacuum, and it has significantly improved its performance. The longer battery life allows the vacuum to run for about 210-300 minutes, depending on the usage and model of the robot. Itâs great knowing I can get these extended run times, especially for larger cleaning tasks.The fast charging feature is also a plus. It charges from 0 to 100% in about 3 hours, which is very convenient for my busy schedule. With the battery capable of lasting for up to 500 cycles and only losing about 5% capacity over time, I feel confident in its longevity.Safety is always a concern, and this battery has built-in protections against short-circuiting, overheating, overcharging, and more. Itâs reassuring to know that it complies with safety standards and has been tested rigorously with CE, ROHS, FCC, and UKCA certifications.Installation was a breeze and took me only about 2 minutes. I just had to remove two screws, disconnect the old battery, and connect the new one. Itâs straightforward enough for anyone to do without much hassle. Just remember to fully charge the new battery before the first use and to keep it charged after using it to maintain its health.Overall, I highly recommend this Eufy 4000mAh replacement battery if you need a reliable power source for your robot vacuum. It improves performance and offers peace of mind with its safety features!

Works perfectly
This battery resurrected our dead Eufy robo cleaner. The vacuum cleaner cleans longer and better. So glad I bought this battery.

Perfect replacement
The battery is packaged well and fits perfectly in the spot.We have a Robovac 30C with a 2600amh battery. It’s a couple years old and we were getting about 45-50 of cleaning. I put the new battery in which is 4000mah so I was hoping to get about 2 hours of cleaning with the understanding that the other battery had lost some capacity over the years. This wasn’t the case, but that’s ok. I still got about 1 1/2 hours of cleaning which is still a nice step up.Overall for the money, this is a no-brainer. I’d highly recommend this.

The battery fits my 11S but stopped working after less than 2 weeks of use. It will charge but then die almost immediately after leaving the charger.
