Why did you pick this product vs others?:Bought this battery a few months ago and it's still working fine, charger is holding like new.

I thought my eufy was broken. Looked it up and it was battery issue so I ordered this battery and now it works!!! Very easy to replace the battery. Hope it lasts for a long time! Fyi i got this batter because it wasn't charging, red light came on after serious of blinking orange light.

I bought the eufy almost 2 years ago and I have never been happier! The other day after over 700 vacuum and recharge cycles, the battery lost power. 2 days and 20 bucks later, she’s as good as new! 2 screws, 1 plug, 3 minutes…that’s all!My kids have 2 cats, and I was buying a “big box store” vacuum every year and a half, even the “good” brands, and they were garbage, beyond repair. I bought the Eufy on a whim, figuring I’d use it while I did research to find a decent vacuum that would last long, never imagining I just did.Every day I was vacuuming with an upright before I got this, and once I got this vacuum, my carpets got cleaner! Not kidding!Get the brush kit, and change those out every few months. I’ve spent less than $200- for the vacuum, brushes and battery these last 2 years, when I would be in almost $400- on thr “good” vacuums that I would have to push around myself.Love it! You can’t go wrong here.

I purchased this lithium battery in January for my robot vacuum, hoping to rejuvenate its cleaning prowess and reliability. Initially, I was thoroughly impressed. The battery life was excellent, and my vacuum could complete its cleaning cycles with power to spare, exactly what I was looking for.However, just two months in, I’ve noticed a significant drop in the battery’s performance. By March, the battery began draining much quicker than when it was new. It now struggles to hold enough charge for the vacuum to complete its tasks, which is disappointing considering its strong start.To add to the disappointment, I’ve found myself unable to return or exchange the battery since its return period has ended. This limitation has left me in a difficult position, as the initial promising performance has not lasted, and now I’m left with a battery that drains too quickly, without the option for a return or exchange.While the battery was an excellent fit at first, providing the boost my robot vacuum needed, the longevity and reliability of the battery have been underwhelming. I hoped for a more durable solution to my vacuum’s power needs. It’s unfortunate to see such a decline in performance over a relatively short time, compounded by the inability to return the product after quickly passing the return window.Overall, if you’re looking for a quick fix, this battery might serve you well in the short term. However, be prepared for a potential drop in performance and battery life, as I experienced, and be mindful of the return policy duration. I’m now on the lookout for a more reliable long-term solution to ensure my vacuum can keep up with the demands of my home without frequent replacements or recharges.

I don't know how to do much handy work around the house. Ordering this was kind of a dare I imposed on myself. My Eufy RoboVac's battery died and I just couldn't take it. So I took a chance. After I received the battery, I sort of put it on a shelf and stared at it for a couple of months... I couldn't convince myself to try, the stakes of me failing being so high.So one week ago I finally summoned the courage to attempt changing the battery on my cleaning robot. Took out my toolkit thingy I bought but have never used, and chose a pink screwdriver. Opened up the battery compartment and faced my fears. There they were, the dreaded wires. Turns out, this system was made for people like me. I did not have to deal with the wires, they are attached to a plastic piece that you detach from the robot, and the new battery comes with the same plastic piece that you just attach.Done, and robot is working. If only everything was so easy

Last longer than original for run time. Charge time us the same. Good value for easy replacement.

Still no issues after a few months... So that's good!
