How to Extend the Life of Your Car Battery

Your car battery is the heart of your vehicle’s electrical system, responsible for starting the engine and powering essential components like lights, radio, and climate control. A well-maintained battery can last anywhere from three to five years, but neglect can lead to premature failure, leaving you stranded at the worst possible time. At Smith’s Service Center in Evansville, IN, we help drivers maximize the lifespan of their car batteries with expert maintenance and practical tips. Read on to learn how you can keep your battery running strong for years to come.

1. Keep Your Battery Terminals Clean

Corrosion is one of the most common culprits behind battery failure. Over time, dirt, grime, and corrosion can build up on the battery terminals, preventing a proper electrical connection.

How to Clean Your Battery Terminals

• Mix a solution of baking soda and water.
• Use an old toothbrush or wire brush to scrub away corrosion.
• Rinse with clean water and dry with a cloth.
• Apply petroleum jelly or terminal protector spray to prevent future buildup.

If you're not comfortable doing this yourself, our technicians at Smith’s Service Center in Evansville, IN, can clean and inspect your battery terminals during routine maintenance.

2. Limit Short Trips

Your car’s battery recharges while you drive. If you only take short trips, your battery may not have enough time to fully recharge, leading to reduced performance over time.

How to Prevent Battery Drain from Short Trips

• Combine multiple errands into one longer trip.
• Drive your car at least 15-20 minutes at highway speeds once a week.
• If you don’t drive often, consider using a trickle charger to maintain battery charge.

At Smith’s Service Center, we can test your battery’s charge and let you know if it's being affected by short trips.

3. Avoid Extreme Temperatures When Possible

Both hot and cold weather can take a toll on your battery. Extreme heat causes fluid inside the battery to evaporate, while freezing temperatures slow down the chemical reactions necessary for it to function properly.

How to Protect Your Battery in Different Seasons

• In hot weather: Park in shaded areas or use a car cover.
• In winter: Keep your car in a garage if possible.
• Check battery fluid levels (if applicable) and top off with distilled water if needed.

If you're experiencing battery issues in Evansville’s unpredictable weather, visit Smith’s Service Center for a battery health check.

4. Ensure Your Battery is Secure

A loose or improperly mounted battery can vibrate while driving, leading to internal damage and reduced lifespan.

What You Can Do

• Check that your battery is properly secured in its tray.
• Avoid hitting potholes and rough roads at high speeds.
• Have your battery checked during routine maintenance at Smith’s Service Center.

We can inspect your battery's mounting and ensure it's firmly in place to prevent premature wear.

5. Turn Off Electronics When Not in Use

Leaving headlights, interior lights, or your radio on when the engine is off can drain your battery quickly.

Best Practices for Preserving Battery Life

• Double-check that lights are off before exiting your vehicle.
• Unplug phone chargers and accessories when the engine isn’t running.
• If your car has an automatic shutoff for lights, verify that it’s functioning properly.

If your battery keeps dying unexpectedly, bring your vehicle to Smith’s Service Center in Evansville, IN, for a thorough inspection.

6. Test Your Battery Regularly

A weak battery might still start your car, but it could fail at any moment. Regular testing can help you avoid unexpected breakdowns.

When to Test Your Battery

• Every six months as part of routine maintenance.
• Before long road trips.
• If you notice slow engine cranking or dimming headlights.

At Smith’s Service Center, we offer professional battery testing in Evansville, IN, so you’ll know exactly when to replace your battery before it leaves you stranded.

7. Drive Your Car Regularly

If a car sits for long periods without being driven, the battery will slowly lose charge.

How to Keep Your Battery Charged in Infrequently Used Vehicles

• Drive your car at least once a week for 15-30 minutes.
• Use a battery maintainer (trickle charger) if the car will be unused for extended periods.

If your car sits unused for a while and won’t start, visit Smith’s Service Center in Evansville, IN, and we’ll diagnose whether your battery needs a recharge or replacement.

8. Check Your Alternator

Your battery relies on the alternator to stay charged. If your alternator isn’t functioning correctly, your battery won’t hold a charge, leading to repeated failures.

Signs of a Failing Alternator

• Battery warning light on the dashboard.
• Dim or flickering headlights.
• Electrical issues, such as power windows operating slowly.

If you suspect an alternator issue, bring your car to Smith’s Service Center in Evansville, IN, for a full charging system inspection.

9. Avoid Overloading Your Electrical System

Modern vehicles have more electrical components than ever, including infotainment systems, heated seats, and advanced lighting. While these features enhance comfort, they also place extra strain on your battery.

How to Reduce Electrical Load

• Use seat warmers and heated mirrors only when necessary.
• Turn off high-drain electronics when idling.
• Upgrade to a high-capacity battery if you have aftermarket electronics installed.

Not sure if your battery is up to the task? Our experts at Smith’s Service Center can help you choose the right battery for your vehicle.

10. Replace Your Battery Before It Fails

Even with proper maintenance, all batteries eventually wear out. If your battery is more than three years old, have it inspected regularly and consider replacing it before it fails.

When to Replace Your Battery

• If it struggles to start your engine.
• If it has visible corrosion or leaks.
• If it fails a battery load test.

At Smith’s Service Center in Evansville, IN, we offer high-quality battery replacements with professional installation to keep your vehicle running smoothly.
