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

This battery has much higher capacity than the original. Now my Roborock s7+ can clean the house (1000 sqft of cleaning area) with about 40% charge remaining in the battery, whereas with the original 5200mAh battery, it used to have to return to the dock for a 2nd charge to complete the cleaning. I recently returned a different brand battery (advertised as 6800mAh) because it held less charge than the original. Glad to finally find one that lives up to the published specs.

Update 2: The battery actually FRIED my vacuum BMS circuitry - I got an entirely new OEM battery and the vacuum does nothing the instant it leaves the charger. Diagnosed it as a BMS circuitry over voltage failure. Do not buy this battery.Update: Well after two weeks (so much for updating after a year lol)+, the battery is completely dead. It reads at 100% but as soon as the vacuum steps off of the charger it dies. Adjusting to one star.So far this battery meets or exceeds the original battery in my Roborock S6. I can't speak to discharge rates while idle because I leave it charging on the dock (as do most). I will update this review in a year or earlier to report back on longevity.

Drop in replacement to our roboeock s4. The old battery had gotten so bad that it could not even vacuum the downstairs without powering off halfway through at 50%. With the CC capacity of the upgraded battery it will finish the floor at Max suction and still be at 75%.

Battery caused issues with my S4. I reached out to seller for refund but they did not accept but offered 1/3 refund.They claimed that the battery would not cause issues but it seams I am not the only one with problems.

I thought my vacuum was done for. But after getting this battery it came back to life! Installing the battery is easy for just about anyone. If not there are YouTube videos that can help. This battery is a perfect fit for the Roborock S5. It has long lasting battery life. Which is needed if you use the vacuum on turbo alot.

Ordered to replace an aging OEM battery, but my S4 can only vacuum for 45min.unfortunately，It was very less powerful than OEM battery. It was giving very less cleaning time.The advertisement say "Upgraded 7200mAh capacity", it is a lie!

It fit like original. I do not believe the capacity is correct, or as it is rated. Lasts about half the time of the stock 5400 mAh, four year old battery that I replaced. Would not buy again from this vendor. Amazon has accepted the return request.

Did not work on my S6 Pure. Not sure if I received a defective battery. After I installed it I put the vacuum on the charger and it wouldn't start cleaning or anything. The charger recognized the battery because the power button would blink but would do nothing else after that. I would press the charger then it would automatically say starting to charge and start blinking again. Bought a different one and that was smaller and it worked.
