6800mAh Replacement Battery for Xiaomi Roborock S4 S5 S6 S7 S50 S60, Battery for Xiaomi Roborock Q5 Q7 Pro/Max+，for Xiaomi Mi Robot, Mijia 1. and 2. Generation Vacuum Cleaner (14.4V/97.92Wh)

Amazing replacement battery! I ordered a different battery before this one, supposedly 12800mah that didn’t even last as long as the current 8 year old 5600mah battery that came with the vacuum… this battery on the other hand finishes the entire vacuuming in one go and fishes at 50% where my current battery has to go back to the dock to recharge to clean the entire floor. Very satisfied, happy to have found a good brand for batteries.

This battery 14.4 V 6800 mAh seems good but I still hve a problem. this battery runs MUCH longer than the last 14.4 V 7200 mAh did.

Works well

I bought this 6800mAh replacement battery expecting a serious upgrade in runtime—what I got was a major letdown. Within just 15 minutes of regular use, the battery discharged 79%, which is nowhere near the advertised capacity. If anything, it drains faster than the original battery it was meant to replace. Not sure if it’s defective or just poor quality, but I definitely wouldn’t recommend it if you're looking for reliability or longevity.

After several years of use the stock battery on my Roborock S4 would no longer hold enough charge to complete a cleaning job. This battery is a perfect drop-in replacement. It has a somewhat higher rating than the original, which may be handy if I want to clean several large areas of the house all at once.

The battery did not charge. The company should test them better. That said, they took the return without any problem. Just a minor inconvenience for me, I found another brand that works fine.

Works perfect.Battery life is excellent, cleans my entire 2300 sq ft home with one charge.My roborock works like new.The vacuum would clean 2/3 of home then go offline and stop.Replaced the battery and works perfect.
