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.

Perfect fit. Works great.

1.5 years since purchase still works fine. Highly recommend.

Perfect fit and replacement for our OKP K3P Vacuum, which had dead battery after the warranty expired. Instead of trashing the vacuum, I searched the part number for the battery and this came up. Slightly more mAh than the stock unit. I'm fairly certain this is just four 18650s daisy-chained together, but it fit correctly into the pocket in the OKP Vacuum, despite not being mentioned as a match for my particular vacuum. Easy install - it's working like new again and holding power. Mainly just mentioning the brand/model of vacuum I'm using this for since I didn't see it in any other reviews. Probably a clone of another brand or something, but hopefully this helps someone buy with more confidence. Stop throwing away technology and try to fix broken things!

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.

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

funciono super bien en mi robot vacuum eufy, aun no he tenido problema, esta como nueva volvió a ser de nuevo, es como si hubiera remplazado eso por una totalmente nueva

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 was relieved to see that the battery fixed my robotic vacuum. It was delivered with enough of a charge to do a run. I didn't have to charge first to see if it worked. Arrived VERY fast.

No se puede recargar, para devolverla tengo que pagar 1,200 pesos o 63 dlls., mas del doble de lo que cuesta, no pude hablarlo con servicio al cliente, No pude contactar al vendedor, La app no me da la opcion solo me da etiquetas de devolución.

Battery install was quick and easy
