Based on information provided it is reading like:
Bike is charging
The battery is able to accept a charge
Battery is UNABLE to maintain a charge.
Consider a battery load test.
Then a parasitic drain test using a digital meter between negative battery post and disconnected negative battery cable would be a final test.
An aftermarket alarm or some solenoid clicking could drain a battery and the parasitic drain test would help investigate that situation.

This is what you do after you verify that the battery is no going dead by itself due to excessive internal leakage. As shown in the video the first thing you need to verify is that the battery is good.
