When does a car battery need to be replaced?

Car batteries supply power to critical systems like the lights, ignition, starter motor, and other electrics. The battery can typically last 3–5 years, though it may be less depending on the mileage and driving conditions.

When the engine is slower to start, the electrics start to falter, the bulbs flicker or look dimmer, or the battery warning light displays on the dashboard, it’s likely a sign that the battery isn’t performing how it should. A visual inspection of the battery may reveal cracks, bulging sides, or corrosion buildup around the terminals.

Always ensure that your vehicle is serviced annually. For your safety, battery health should be checked at every service.
