What factors influence the service life and power of the starter battery in a vehicle?

The starter battery is a wearing part and ages through charging and discharging cycles, which reduce its capacity over time. The cold reduces the battery performance, while the engine's starting current demand increases, which often causes starting problems in the winter. Short journeys decrease the service life as the battery is not fully recharged. The constant energy consumption by electronic loads or additional accessories, such as dash cams, can also discharge the battery, especially if the vehicle is parked for a long time.
