In many cases it depends on how much and how often the car is driven. It may not take time to fully charge the battery.
Ambient temperature is also important. Now we have 0° C and faster discharges the battery.
Wife's auto is not used on weekends. So I need to setup the date and time on Monday.
I think
this battery has a charge/discharge cycles and will need to be replaced. Already in use since 2o17.
The date and time are also automatically set if there is a GPS item. Since this mini has problems with interference and GPS
if it is housed in one housing, this variant never works me.
In my car, the GPS is carried by cable +40cm and after 3-4 minutes of driving date and time are set automatically.
Good luck
