## 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.
