Tip: How often should you test your car battery?

Testing your car battery is an important part of vehicle maintenance. Ideally, you should test your car battery at least twice a year. This bi-annual checkup ensures optimal battery performance and helps prevent unexpected breakdowns.

In areas with extreme weather conditions, such as very hot summers or very cold winters, it is recommended to test your battery more frequently. Extreme temperatures can seriously affect battery performance and life. Testing your battery before these seasons helps ensure that your vehicle remains reliable.

Additionally, if you notice any signs of battery failure, such as difficulty starting the engine, dimming headlights, or electrical problems, it's best to test your battery immediately. Catching battery problems early can save you from an inconvenient and potentially costly breakdown.
