Clean charging contacts with alcohol and also clean the two little thingys on the dock that connects with the charging contact on the Roomba hope this helps.
I had the same problem. Cleaned contacts and it didn't work. I removed the battery and it started working again with a full battery. I think that it wasn't reading the voltage correctly but the base was and can't charge a full battery thats why the base will test the battery then turn off.
I have exactly the same problem and base on your video the same spot on both the roomba right contact and also right charging dock contact. Did you manage to find the root cause of the issue?

Maybe the dock was unplugged

Clean contakts
Are your wheels worn down?
Have the same problem. The charge connectors get pushed into the Roomba 980. Reported it and got a new one. About a year later it's happening again…

Worst vacuum ever
On the side there should be a hole to plug the room a in directly, I would try that then you can go from there
how old? could be the battery has gone in which case replace it, and you could get a altimeter to check the contacts and base station.
