Most car batteries are rated for three to five years, but real-world life depends heavily on how the car is driven and where it is parked.
In the long run, heat is harder on batteries than cold, because it speeds up the internal chemical breakdown that eventually causes failure. Cold is what usually reveals a weak battery first.
The best check is a load test, which measures actual capacity rather than just voltage. A battery can show a healthy voltage and still fail under load.
