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

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.

Worked for 5 months and then stopped charging. Messaging the seller to see if they will replace under their warranty. - update: the seller offered a full refund and replaced the battery for free. The new one is working like a charm and hopefully it continues to do so. This seller stood behind the product and helped when the first one failed

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.

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!

Great

I have a Eufy G30 edge. Original OEM battery had a run time in excess of 100 minutes. After three years, it had deteriorated to about 40 minutes. I bought this as a replacement. I charged it overnight and tried it out. It had a runtime of 48 minutes. I repeated the cycle of charging and running two more times with the same result. I thought I had a defective battery so I contacted Amazon who then replaced the battery for me. I repeated this charging and running process with the second replacement battery only to find that it had a runtime of 50 minutes. So now I am less convinced that I had a defective battery, and more convinced that this is just a poor substitute for the OEM battery. I do not recommend this battery.

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