PRODUCT DESCRIPTION - Battery Replacement for Eufy RoboVac X8 Series Robot Vacuum X8, X8 Hybrid, X8 Pro, Model PA61 BatteryUNBIASED - 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.

Bought this battery for my Eufy x8 robot vacuum. After hundreds of uses over the past 2 years I can tell the original battery is starting to lose some of its overall health and run times are reducing. I got this battery to replace the current one early so I can get more time from my eufy vac as it does a great job and I don’t want to replace it. This battery is a perfect fit as OEM and even the specs are nearly identical. I’ve used it several times now and it’s had at least 2 cycles and I can tell the battery lasts like it was brand new. It’s difficult to determine how much longer it lasts or holds charge for without rigorous testing but for now this is a great solution as opposed to buying Eufy brand batteries or replacing the vacuum entirely.
