Real 7200mAh 14.4V Battery for Roborock S7 S6 S5 S4 Q7 Max S50 S60 S70, T4 T6 T7 T60 T65, for Xiaowa E20 E25 E35 C10, for Xiaomi Mijia/Mi 1st and 2nd Gen Robot Vacuum Cleaner

Seemed to work OK but after two months it died. Return period expired 3 weeks ago. Not recommended.

I set my battery capacity tester to 2A constant current, and this battery took almost 3 hours to fully discharge. The final result was 5.8Ah as you can see in the photo. That's less than the 7.2Ah that the seller claims, but still, this appears to be the best out of 3 replacement batteries that I bought so far (the cheapest of which only lasted a few months and then had only 2.7Ah left). I consider this battery a very worthy 8-year birthday present for our hardworking trusty little Xiaomi Mijia 1st gen robot vacuum cleaner that I bought in January 2017 and which has been cleaning the 1st floor 3x a week ever since.

Worked great for about six months, but now the robot dies unexpectedly halfway through cleaning without being able to make it back to the dock. When placed back on the charger it jumps from 0% to 65% charge. I'm guessing a cell is bad.

The battery is a complete waste of money. It only held a charge for one run and hasn't worked since. I wish that I had tried it out before the short return window expired.

Battery after 3 months is already dead. Do not order unless you want a quick fix. Was great for first 2 months 90 min run time. Now it's down to 28 mins. Update* Reached out to the customer service and they replaced the battery. Works great again

Bought in feb2025 it died aug 2025 and will not charge. Prior replacement battery only lasted 6 months too

The battery is working well, and 7200mAh compared to 6800mAh for competitors allows to complete even mopping cycles in one charge. Great buy so far.

Worked great for about 3 months. Now, it won't hold a charge at all. Last few runs, I've found my roborock stranded somewhere in the house with a dead battery. Today, it was charging for hours and when I tried to run it again just to do a spot cleaning of one zone, the roborock moved about 3 inches before it shut off.
