My robovac’s battery needed replacing. So, I went to the manufacturer’s website and was about to order one. The price was about $35.00. Then, I decided to check on Amazon for after market manufactures. Lo and behold, I found this seller offering their version of the same battery model at a fraction of the original manufacturer’s price.. After reading several of the customer reviews, I was impressed enough to give them a shot. Installation was easy, and to date, I’ve had no issues with charging or performance. My experience after about 2 months of use is that it performs exactly as the OEM battery performed. Therefore, I highly recommend this seller for this particular product.

It fit. It was easy to install and it works like a charm.

This is my second purchase of this product. They last about 1 year.

Update: the seller reached out and refunded my order after my negative experience. This seller is very fair.Purchased Feb 2024, by Jan 2025 we have had multiple battery errors and have almost had to replace this battery multiple times. I feel like it should last longer than a year and I don’t like receiving the battery error notifications.This was easy to install. We use our robot 2-3 times a week for reference. We get an error that this battery won’t charge once a month or every other month.

It made my machine do what it did originally when I bought it years ago it fit perfectly.

Let me preface this review by saying that this battery works perfectly fine. I have had zero issues with it charging and powering the vacuum. My problem lies solely in the claim that it lasts longer than the original battery. The original battery in my vacuum lasts about 45 minutes currently and it used to last around an hour. We recently moved into a bigger house and it cant quite clean on one charge. I saw that this one lasts 120-180 minutes and was immediately sold. I thought to myself, even if I only get 90 minutes I'm doubling my cleaning time, this is a no brainer. This brand new battery lasts me....4-6 minutes longer than the two year old original battery. Which means it doesn't even last as long as the original did when it was brand new. I will be returning this in hopes of finding a better brand that isn't making false claims. What a letdown.

I noticed that our Eufy robovac wasn’t working its usual 60 minutes, so I replaced the battery. Sadly, the replacement had a quite short lifespan. It stopped working immediately even after an overnight charge! I realized that I needed a much-higher capacity battery. After a quick exchange to this battery, the vac was up and running better than brand new! The time is extended to a full 90+ minutes thanks to this battery! I have had to recall it back to base when it has done the entire downstairs floor! This battery is a perfect fit and definitely worth the cost!

It's weird Amazon would require a rating for longevity on a battery one just received. Having said that, this battery has our vacuum working like new, and has run for about 5 or 6 cycles (uses) so far. In fact, I think the run time is longer than with the original battery. It goes a good 90 minutes, now. Installation was easy, so we'll see how long this battery lasts for the long run. I will try to remember to update in about a year.
