PRODUCT DESCRIPTION - 5200mAh Replacement Battery for Eufy Robovac L70 Hybrid Series Robot Vacuum fits Part Number INR18650M26-4S2P Lithium Ion Sweeping Robot Battery 14.4VUNBIASED - 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 27 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 are facts not opinions. I was lucky enough to have a friend who is a very talented electrical engineer for testing.

I had this on the Eufy L70 Hybrid robovac for several days and it never charged. The blue lights kept blinking but it never stayed blue to indicate it was charged. Returning if for a refund. I tried to buy a battery directly from Eufy but they are giving me such a run around about it that after 3 years of using this vacuum I will be buying another brand that has parts readily available.

My Eufy Robovac L70 Hybrid, once a cleaning champion, started struggling to keep up. Cleaning cycles became shorter as the battery life dwindled. A replacement battery seemed like the logical solution, and after looking at options, I landed on the Gikysuiz 5200mAh Replacement Battery. I'm glad I made that choice as this battery has so far performed just like a new original unit.

The manufacturer brand works better for me.

I bought this less than a year ago and it’s already failed. Super disappointed.

I've had this battery charging for over 24 hours and the L70 unit still shows the "breathing purple," indicating the charge is under 20%. And of course, I didn't try testing this battery until it was outside the return window, so that's on me. But this is junk -- word to the wise.

worked fine for a while, now it just drops power and leaves my robot vacuum wherever it dies without warning. Even with the old battery, it had enough power to get home. This one does not do that....

Only worked long enough to be outside the return window
