Works great. My Eufy is up and running again.

Original battery of my Eufy L70 stopped holding charge after 2y. Eufy customer service mostly useless. So bought this one and now it works great again! Also was very easy to swap.

Had issues with other suppliers on Amazon and the batteries will not charge. This one is working great. Eufy was out of batteries for the L70 and needed a different source for a replacement. This one does the job and works

Replaced my battery in the eufy robo vacuum which would not charge and it works now.

Easy to install & works perfectly. My robovac charged right up and is working like normal again!

Eufy L70 like new again after using this replacement battery..

Doesn’t charge and battery dies after 1 minute of use.

Guilty feet have got no rhythm. I assumed when I purchase my robot vacuum that life was complete. That I would never have to vacuum again. If you are confused about the title or first line.. A great artist from the 80's sums up my experience with my robot vacuum. Just having some fun. Anyway, the last thing I considered with my new toy was it's longevity. And it has not disappointed until recently. For years this tool has done the unlikable job of vacuuming and has done it well. It seems there is a limit though. The Battery! Who would have thunk. It is the heart of this appliance afterall. I just took it for granted that heart would keep on beating.The little robot vacuum tried not to die. It would send itself back to the dock to charge but after a while it would forget to pick up where it left off. It forgot how to dance. And the battery is to blame. It needs a heart transplant. And here is the solution.The bottom cover of the vacuum needed to be removed for the installation. Just a handful of screws and it pops right off. Then the old battery is easily accessible. Just unplug old and plug in new. I paid attention the wire colors to make sure it was plugged in correctly. Easy. Reinstall the bottom cover and place on the charger. My little robot vac now has new life. Hopefully it will last many more years and keep me singing. One odd thing is that the webpage mentions the battery at 5600 mAh and the battery I received says 6800 mAh. I don't know if this matters though. It seems to work just fine.
