For those with used cars, a car that doesn’t start can be particularly disturbing because it can be due to an array of problems, but most likely, it comes down to two things — the car battery (most likely, or the alternator that feeds the battery during operation. Nowadays, it can be safely said that as prices go up, the quality and durability have decreased – unfortunately – so it is more important to keep battery maintenance a high priority with a few tips.
Proper maintenance can extend the life of your car battery and ensure reliable performance. Here’s a guide to the best practices:
Regular Inspection
- Check the battery terminals: Ensure the terminals are clean, tight, and corrosion-free. Corroded terminals can affect performance.
- Inspect the battery case: Look for any cracks, swelling, or signs of damage. A swollen battery indicates overheating and needs replacement.
Keep It Clean
- To remove corrosion, Use a mixture of baking soda and water and a wire brush to clean the terminals. Rinse with water and dry thoroughly.
- Apply anti-corrosion spray or grease: This protects the terminals from future corrosion.
Ensure Proper Charging
- Avoid deep discharges; batteries last longer when kept near full charge.
- Drive your car regularly to keep the battery charged. If the car isn’t used often, consider using a battery maintainer or trickle charger.
Maintain Optimal Fluid Levels
- For batteries with removable caps, check the electrolyte levels periodically.
- Use distilled water to top off the electrolyte if levels are low. Never overfill.
Test the Battery
- Use a voltmeter or multimeter to check the voltage regularly. When fully charged, a healthy battery should read 12.6 volts or higher.
- Have your battery tested professionally during routine maintenance.
Protect from Extreme Temperatures
- Heat: High temperatures can accelerate the battery’s internal chemical reactions, leading to shorter life. When possible, park in shaded areas or garages.
- Cold: Low temperatures reduce battery performance. If you live in a cold climate, use a battery blanket or insulator.
Avoid Excessive Draining
- Turn off lights, radio, and accessories when the engine is off to prevent battery draining.
- Ensure all electrical components are off before exiting the car.
Secure the Battery
- Ensure the battery is securely mounted to avoid vibrations that could damage internal components.
Replace When Necessary
- The average car battery lasts 3–5 years. It should be replaced when it shows signs of wear, such as slow starts or frequent charge loss.
Small Tips:
- Keep a portable jump starter in case of emergencies. A good one is small enough to fit under the back seat.
- Familiarize yourself with your car’s specific battery type and maintenance requirements.
