Your vehicle’s battery powers everything from the ignition system to lights and electronics. Over time, corrosion, extreme temperatures, and infrequent use can reduce its lifespan. Here’s how to maintain your battery and ensure reliable performance year-round.

Step 1: Inspect the Battery Terminals

Pop the hood and locate the battery. Look for corrosion (white or blue powder) on the terminals.

Step 2: Clean the Terminals

Disconnect the negative cable first, then the positive. Use a wire brush and baking soda solution to clean the terminals.

Step 3: Check the Mounting

Ensure the battery is tightly secured in its tray. A loose battery can vibrate, causing internal damage.

Step 4: Test the Battery Voltage

Use a multimeter to check voltage. A healthy battery should read around 12.6 volts when the engine is off.

Step 5: Keep It Charged

If your car sits for long periods, use a trickle charger to maintain charge. Short trips may not fully recharge the battery.

Step 6: Monitor Battery Age

Most car batteries last 3–5 years. If yours is approaching that range, consider having it tested or replaced.

Battery maintenance is a quick but important habit that can save you headaches — and towing fees. Add these steps to your regular maintenance routine and drive with confidence.
