CITYORK Li-ion Replacement Battery for Roborock S7 S6 S5 S50 Max/MaxV/MaxV Ultra/Pure Xiaomi Robot Vacuum Cleaner Replacement Battery, for Roborock Q5 Q7 Pro/Max+ Mijia 1st and 2nd Generation

So far so good. Exactly the same as the original battery. Been using a week now and Mr Kenny (we named ours) is back to cleaning the whole place without needing to charge every 5 minutes.

Replaced the battery in our Roborock S7 about 3 months. It's been working with no issues since.

I was worried that a third party battery might not work as well as the original, but this has restored the run time of my Roborock to how it was when new. Would recommend.

Returned as would get to 50% charge then die. No good sadly!

Good value

The battery was easy to replace using the photo displayed as a reference for placing it in my vacuum, and it worked great. In my opinion, the battery improved the performance, but that may be because the previous one was becoming old. Highly recommend!

One year of pretty moderate use (robot out once or twice a week) and unfortunately this battery is already 'jumping to zero' from about 20% which suggests it's dead.

Excellent

I recently purchased this battery ,based on the description the battery lasts for three hours. However, after multiple tests, I found that it only lasts approximately one and a half hours only which is significantly lower than advertised.

Super Akku. Unser Robi ist damit jetzt wieder schneller und viel ausdauernder unterwegs. Ist schon einige Monate im Einsatz und kein merkbarer Leistungsverlust.

Snelle levering. Fatsoenlijk verpakt en werkt perfect

Var lätt att byta ut. Dammsugaren kan åka runt i huset nu i över en timme på fullt sug, gamla orginal batteriet höll max 10 minuter. Bra ersättning!

Ordered a similar after-market battery on amazon from another seller before, when it arrived it was at 0% battery (clearly a bad sign), and indeed my roborock s6 lost power in the middle of cleaning a room. This one on the other hand arrived still charged, lasts a long time, no problem with it.
