This battery arrived, charged and is performing as expected. The Eufy vacuum has been renewed!

Good quality and value.

Good so far! I thought the battery died but it was the roller that was jammed.

First impressions are good, battery installed easily, vacuum charged right up and appears to work fine. The proof is in the capacity and longevity which will not be known for a while so I do not like doing early reviews on such items.

It gave a new lease on life and function to my ild vac robot (Eufy) it runs noticeably quieter like it’s new again

Awesome battery. The Eufy I had was almost 5 years old and was running dead after 30 min. This battery was quick and easy to install and now we're getting full clean cycles again.

I typically wait awhile until reviewing a product here so please know that I will update this review if anything changes my opinion. I purchased this battery as a replacement for the original battery in my Eufy 11s robot vacuum. After 2 1/2 years with my Eufy it stopped working. It was giving a red light and making beeping noises when it was on its charging dock. The Eufy Owners Manual trouble shooting guide was not helpful and I thought my poor Eufy was done for. Fortunately I did some research and decided to try replacing the battery before relegating it to the waste disposal. I ordered this battery and it was a perfect fit and replacement for the original. It took only a few minutes to install. I then put the Eufy onto its charging dock and waited until it was fully charged. The Eufy went to work and vacuumed my floors for an hour and 10 minutes! Previously it only worked for 45 minutes before needing to recharge. I was very pleased! Back on its dock the Eufy took about 3 1/2 hours to get to full charge. This battery has a larger capacity than the original Eufy so I think that’s why it ran longer and perhaps took a slightly longer amount of time to charge. After first use I am very happy with my purchase and highly recommend this battery.

I really wanted to give this battery a five star review because the first couple days it was a long lasting, but it now has gotten slower after a few days. It takes longer to charge and it doesn’t last so I’m not sure how long this battery will last. I hope it lasts longer than I’m afraid it will.
