Battery Lifespan of Group 34 in Canada

A Group 34 battery typically lasts 3 to 5 years in Canada, depending on your driving habits and the weather. Cold starts, short trips, and high accessory use (like heated seats and headlights) can shorten the battery’s life. It’s a good idea to test your battery yearly once it hits the 3-year mark.
