This replacement battery saved me a lot of money. Works perfectly for Eufy robovac! Easy to install and good battery life.

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.

I had a robot vacuum that was not used for a while and eventually wouldn’t turn on. We almost tossed it but decided to try a battery replacement to see if that would solve the issue and it did! It fit my eufy robot vaccum perfect and allowed us to continue using the vaccum. It is extremely easy to replace and even comes with a little screw driver.

It is a great little vacuum. It works well, picks up more animal hair than I realized we had. A great purchase so when the battery began to fail, once again I went to Amazon to find the best replacement battery. Delivery was quick and installation was simple. Way to go Amazon!

I bought this battery because my robo vacuum would no longer turn on. The good news is that it works fine and was among the cheapest options available. The only thing I've noticed is that my robo vac will now turn on randomly. I suppose that could be a coincidence and not related to the battery, can't say for sure. So I just turn the vacuum off using the button on the bottom, a mild inconvenience but not a huge deal.

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.

Battery is not compatible with Eufy vacuum cleaner 15C Max. Eufy 15C Max has a three terminal battery connector. The "replacement" battery has a much smaller two terminal connector.

Perfect replacement battery! Came with screwdriver and instructions. Charged up and robo vac working again.
