Review: Perfect replacement for my Roborock S4 Max. - As expected this battery fit my Roborock S4 Max and I suspect it will fit other models as well. In case your particular model is not listed ( a common omission) just remove your old battery and compare it to the photos of this battery paying close attention to the shape and plug details. My original Roborock battery was showing reduced run times and usually could not finish our 926 sq. ft. area. The original battery had an accumulated 303 hours and 200 thousand sq. ft. of service life but now needed to be replaced. Questions are: Does this new aftermarket battery work and how long will it last before needing to be recharged? In my case the answers are Yes, it does work and my vacuum ran for 82 minutes, vacuumed 926 sq. feet and returned to the dock with about 40% charge left. So all is good at this early stage. Considering the games that are played with aftermarket power and life claims I'll wait to see if how battery compares to the original OEM one.
Review: It fits just as original, and my vacuum is now renaissance :D - I have a Xiaomi vacuum robot 1, which is pretty good but it is already very old. Lately, It started not to finish a single cleaning and was just shutting down without any reason. I bought this battery as a replacement which fitted just as an original one. 1 to 1 as it's native one and after that all is fine. It keeps I guess even longer battery life than I had when I bought the vacuum. So I am very happy with this purchase.

## Questions & Answers

**Q: Does this battery work with Roborock S4?**
A: Sorry, it can't.

**Q: does it work with roborock s5 max?**
A: It gave me problems because it did not match the original mAH that my Roborock shipped with. Having said that I ordered another battery with the correct mAH and it doesn't work right either, I only get about 60 percent of the stated charge rating. I guess Roborock wants you to order an OEM battery ar twice the cost.

**Q: Does this battery fit Roborock S6 pure?**
A: Yes, it does but will give you problems.

**Q: Does this fit with the Roborock E25?**
A: Not sure. It fits my roborock s4 model.

UPDATED REVIEW: While I originally had some challenges with the first battery, I reached out to Energup and they happily sent me a brand new battery to resolve the issue I was having. The new battery works great! ORIGINAL REVIEW: Bought battery to replace in my Roborock S5 that consistently had low battery warnings. Swapping out battery was quite easy. However, even though this battery is supposedly rated higher than the original at 6500mAh, the Roborock still has low battery issues on every cleaning. My assumption is that the battery isn't actually 6500mAh.
