14.4V Replacement Battery for Eufy RoboVac X8 Series

Battery works well, so far no issues and it fixed the battery temperature too high too low issue. Original battery lasted about 14 months. I'll be interested to see how long this one lasts. Easy install, exact fit.

I strongly recommend that this battery not be bought for the Eufy 8X Hybrid. I bought two, the first worked great until it didn't, error message about the battery, so I bought another in October. The second worked great until suddenly it didn't, another error message. I contact Eufy, did everything they said, did everything recommended on the Internet. Nothing worked. I reset the the Eufy 8X Hybrid to the original factory software, it worked fine, UNTIL the device updated software. Then I got the same error. This is a second time an aftermarket device like a filter and now the battery would not work in the Eufy because of what they built in to the system to prevent substitutes. Aftermarket filters won't work because they don't have the right magnetic strip in them. Now. This time Eufy changed the software so it would only take an Eufy battery. In closing. I bought an Eufy battery for them at a higher price, put in it and the device has worked great for the last 3 weeks. And all my correspondence with their technical support. They never said that a non-Eufy battery would not work in the device. They did give me a hint when they asked me to take a photo of the battery and send it to them but I never did because I didn't want to take the battery out.

Works perfectly! No complaints

Utilized this choice of battery (same specs, etc.) to replace OEM’s original battery that just died. Seems to do the job, however I believe I notice that this particular “brand” just does not have the same “umph” nor do I think it lasts as long as did the original. I suppose you get what you pay for in life. Basic business principle / law. Note: must be 3-4 months now and floors still get cleaned though. Just not so sure I’m going to get a yr or more out of this one. Speculation at this point.

Affordable replacement battery. It does the job

I plugged this battery in and power cycled my vacuum and it seemed that it was going to work. I have had issues with it since. Battery overheating, Eufy notifications saying insufficient charge, vacuum shut down due to battery temp.

This is an exact replacement battery for my Eufy vacuum. It was delivered fast and it was well protected in the box. The install was super easy and my vacuum is working again. This is a great deal for a replacement battery. It’s a perfect fit.

Arrived charged and ready to go. Correct voltage and capacity for the battery. No issues.
