When Should You Replace Your Car Battery?

Your car’s battery will eventually die. You cannot be sure when, but it will eventually happen. Your car’s battery’s life span is determined by several factors, including time, heat, and vibration. To get a better understanding of these three factors, let’s dive a little deeper.


Your car’s battery will gradually deteriorate over time until it can no longer provide enough power to start the engine. How long your battery lasts is determined by your usage of your car. Your car’s battery will have less time to fully recharge if you primarily drive short distances. Additionally, if you leave your car parked for a long time, the battery will self-discharge.


Cooler climates will increase your car’s battery life to five years or more. In warmer climates like ours, the average lifespan of a battery is around three years. Batteries undergo quite a few harsh conditions under the hood where temperatures can reach more than 200 degrees Fahrenheit. To fight off the heat, automakers place the battery in an isolated area or place a heat shield over the battery.


Vibration causes your battery to physically break down over time. The internal components begin to wear and break as you drive your vehicle. To help offset the effects of vibrations, batteries are secured by special hardware that prevents them from moving around. Missing or ineffective hold-downs will drastically reduce the life of your car’s battery.
