Car Battery Lifespan

On average, car batteries last 4 to 5 years.

However, several factors such as weather conditions, driving conditions, and how often you use your vehicle can shorten this lifespan.

Extreme temperatures – both hot and cold – cause batteries to deteriorate faster.

Furthermore, driving in stop-and-go traffic or short trips which don't allow for full recharge can contribute to a shorter battery life expectancy.


When to Replace a Car Battery

If you're experiencing symptoms of a failing battery, such as slow engine cranking or your battery is older than four years old, it's time to consider replacing it.

Voltage readings are another way of determining whether your battery needs replacing; anything below 12.4 volts indicates that it could fail soon.

Even without any symptoms showing yet, a battery that's over four years old has reached the end of its usefulness and should be replaced.
