Cameron Sino New 5200mAh Replacement Battery for Eufy Robovac L70 Hybrid, T2190, T2190G21, PN. INR18650M26-4S2P

My L70 needed a battery and OEM batteries are hard to find. Since there are a lot of these generic batteries on Amazon with not so great reviews, I wanted to post to let people know this works perfectly with the Eufy L70. The vacuum was just randomly dying mid clean and not returning to the charging base. This solve that problem. Cleaned the whole house with battery to spare. The battery pack itself looks and feels exactly like the original. Very solid.

I bought and installed this replacement battery in December 2023 for my Eufy Robovac L70 Hybrid. The battery charges great and is still going strong.

So far, so good with my L70 Hybrid. The original battery would no longer last more than 20 minutes before the thing would just die (and most often under by king sized bed right smack dab in the middle and just out of reach lol). It also would never fully charge and the blue light would just flash as if it was charging. I was about ready to throw the whole thing out, but I figured I'd take a chance on replacing the battery. Was disappointed that there didn't seem to be a lot of options for this model vacuum, and of those that were available, they were kind of spendy and didn't have a lot of reviews. I took a chance on this one, and so far all is good. Replacement of the battery is a bit more difficult than the G30 that I also have. But overall, still a pretty quick process, unless you do what I did and break one of the wheels. While working on replacing the battery, I pushed one of the wheels down, which normally isn't an issue as they are designed for this to happen during operation. Well, one of the wheels must have had something stuck under it, and it snapped the piece of plastic that a spring attaches to in order to give it that springiness. I thus ended up having to take the entire thing apart to get at the component that I broke. And let me tell you, that is quite a task. After a few hours, some gorilla glue, and two full disassembles (due to crossing two of the wire assemblies), I finally had a working vacuum again that lasts the full cleaning duration needed to make 2 passes through my apartment. Just as it did when new. And it now has enough charge to make it back to the base if it won't finish the job in one go. So, if you have an L70 which has a battery that is no longer holding up, take a chance on this. Especially if your vacuum is a year or more old. These batteries will not last forever, and even though replacement costs seem high, they are still pretty cheap compared to batteries I've dealt with in other types of devices. And during the replacement, learn from my mistake and don't break the wheel of your vacuum :)

Working great good product

It loses 1 star because of high price! I will keep this post updated if anything goes bad with the battery lifetime!

I received this replacement with high hopes after reading the reviews. On the two occasions I've run the L70 Hybrid it has been screaming low battery after running only a fraction of the spaces. I was hoping to revive my L70 but it seems the unit has lived out it course.

After searching Eufy's website for a replacement battery, and being told that they do not sell one, I searched Amazon and found this. It was unclear if this would for sure work with the L70 Hybrid. I'm happy to report it does work, and it works great. I found a YouTube video on how to install (very easy) and it has been working great ever since. Recommended.

After we charged the battery, it did clean the entire house in one charge. Perfect.
