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

Got this yesterday. Put it in my robovac hybrid X8. Cleaned out the dust collector and the brushes while I was at it. I let the robovac charge and then Set It Off to clean. It told me my dust collector was full and I ignored it last night. When I started it today it told me the dust collector was full and the filter needed cleaning. I didn't think that could possibly be true but I pulled it out anyway. I was shocked at how much it had picked up. Apparently, this new battery made a huge increase in the amount of suction on this robovac. I had no idea my floor was that dirty and I've never seen it pick up that much in one time. This battery is great

Needed this as a replacement battery for my Eufy robo-vac & it worked PERFECTLY! Followed the instructions, dropped it in & connected the wire harness and it’s never missed a beat on its regularly scheduled cleaning cycle of my downstairs since the replacement. Would buy again from this vendor.

Perfect fit for my Eufy RoboVac X8 Hybrid. Very easy to install. No issues so far.

Replaced the battery in my Eufy X8 hybrid with this. Fit and worked perfectly. Vacuum now clean the entire house again and get a stuck less often.

Fixed our battery issue. Last much longer than the original equipment

Bought this to replace the battery I had due to a battery warning sign I was recording. Come to find out it wasn’t the battery but a hardware issue

My eufy x8 wasnt holding a charge. Put this battery in and all is well with the world again.

PRODUCT DESCRIPTION - Upgraded 6400mAh 14.4V 92.16Wh Battery - Compatible with Eufy RoboVac X8 Series Robot Vacuum Part Number PA61UNBIASED - Amazon Vine reviewers are not paid for reviews, be it positive or negative. I will never recommend a product I would not buy myself. I treat ALL vendors with respect and fairness but my duty is to You, the Amazon customer. I am an Amazon customer too. I have every reason to be sincere in my reviews. If it is junk or treasure my reviews will reflect the products, I give my word of honor.PERFORMANCE – It seems like everything has a Lithium battery in it these days, as battery technology continues grow the sophistication of Li batteries is amazing. These batteries actually have the chips to protect themselves from damage using BMS or Battery Management System. The specs tell the tale. The batteries came in properly charged according to the specification. Don’t be alarmed if your battery arrives at 90% capacity, because that level of charge is sometimes used for battery health, again in some cases. I ran 25 discharge/charges cycles with NO change in capacitance! The amperage was great as a matter of fact. I could detect any drop in charge capacity. Very impressive. You can't get that type of performance if a battery is of poor design and construction. I will definitely keep this company in mind for replacement Lithium batteries and I recommend you give them a try too. The numbers don't lie.UNBIASED - Amazon Vine reviewers are not paid for reviews, be it positive or negative. I will never recommend a product I would not buy myself.
