Upgraded 6400mAh 14.4V 92.16Wh Battery - Compatible with Eufy RoboVac X8 Series Robot Vacuum Part Number PA61

It work perfectly for my eufy. I haven't had issues with it yet.

Eufy died...would not charge. Got this and it did the trick! Cheaper than buying a new robot vac. Disappointed in our Eufy, battery did not last 3-years and our i-robot battery has lasted over 5-years and still going.

I've only had this battery in for less than a month and it's already having issues. Vacuum doesn't charge properly and seems to die WHILE being on the dock. It worked great the first time, but after that it's been nothing but problematic.

it fit perfectly in my robo vac and the connector was perfect match. Upon replacing the old one with this, I have not had any issue or error with my vacuum, and it has long battery life when in use.

Functionally accurate but comparing the charge remaining after a full house vacuum (this 6400mAh) run versus the original 5 year old OEM battery (5800mAh) and this brand new battery is depleted more than the original but 5 year old battery? The only thing that makes sense is they are lying about the their battery. I can’t think of any other reason why the old battery performance is better than the new one except for that one reason. I’ll keep my old for backup Update: It’s going back. Fire hazard in my book. It discharges way too quickly for what’s advertised. Vac died after a room and a half. I felt it’s unstable chemistry so return it goes. Hope it don’t catch fire. Should be banned. IMHO. I don’t mess around with these types of batteries, nobody should.

Great buy

Worked great out of the box’s

Exact fit for my X8 and brought it back to life after the original battery died from years of use. Battery feels of high quality and comes with everything you need to pop off the battery cover to replace the battery yourself.
