Car Battery Maintenance: 7 Tips to Keep it Running Longer
A well-maintained car battery can last for years, but it's also quite fragile. Leaving your car lights on overnight can drain it completely. To avoid getting stranded at the worst possible moment, follow these basic and preventive car battery maintenance tips.
1. Check the Battery’s Water Level
First, determine if you have an AGM battery or a non-maintenance-free wet-cell battery. If it's the latter, check the water level every two to three months. If your battery has fill caps, unscrew them and ensure the fluid barely touches the bottom of the refill hole. Refill with distilled water if necessary, but be careful not to overfill.
2. Inspect Your Battery Regularly
Perform regular inspections of your battery. Check the terminal connections to ensure they are clean, snug, and secure. If they are dirty, clean them with a wire brush dipped in a paste of baking soda and distilled water. Look for signs of rust or leakage, and if you find any, have your battery checked by a mechanic.
3. Avoid Heat When Parking
Whenever possible, park your car in a cool place. Heat causes battery fluid to evaporate, accelerating battery failure. If you live in a warm climate, have your battery load checked by a professional every two years. In colder climates, this check is needed every four years.
4. Check Your Cell Voltage
Regularly test your battery's voltage and charge at a mechanic or auto parts store. A fully charged battery should read 12.5 to 12.6 volts. Many places offer this service for free, and you can also do it yourself with a car battery tester.
5. Use a Car Battery Maintainer
If you're storing your car for a season, use a car battery maintainer. This device keeps your battery charged without overcharging it. It monitors the battery's voltage and adjusts the charge automatically, ensuring your battery is ready when you need it.
6. Don’t Leave the Lights On
Leaving lights on is a common cause of a dead battery. Always check that all lights are off before leaving your car. Unplug any accessories that might draw power from the battery even when the engine is off.
7. Check Your Battery’s Insulation
Extreme temperatures can affect your battery's lifespan. If your battery has insulation, check it regularly to ensure it's intact. If it doesn't, consider having insulation installed by a mechanic.
Perform Car Battery Maintenance Often
Regular maintenance is key to a long-lasting car battery. Don't just focus on the battery; take care of your entire car to ensure overall longevity.
