I'm curious about your parking habits. Do you typically park your car in a garage? And if you do, how often do you go in and out of the garage throughout the day?
The reason I'm asking is that I've noticed a light on the dashboard that indicates the car's main battery (the one that powers all the electronics) is charging the smaller 12-volt battery. I see this light quite often.
However, if you frequently pass by your car and never see this light, it might signal a possible problem with the system that manages the 12-volt battery's charge. This smaller battery is essential for starting the car and powering basic functions.
