H9 Battery Lifespan in Canadian Conditions

The average lifespan of a Group H9 battery in Canada is about 3 to 5 years, depending on driving conditions and usage habits. Extreme cold, frequent short trips, and extensive use of accessories (heated seats, infotainment) can shorten battery life. We recommend annual battery checks after three years to maintain reliability.
