1. Turn Off All Electronics

Make sure all electronics in your car are turned off completely before leaving your vehicle for an extended period of time. This includes your radio, headlights, air conditioning, and other accessories that may drain your car battery. Even the smallest electronic device can slowly sap your battery’s power over time.

2. Disconnect the Battery

If you plan on being away from your car for an extended period, consider disconnecting the battery entirely. This ensures that your battery won’t be drained by any electrical devices left turned on.

Keep Your Battery Clean

Corrosion can build up on your battery terminals, which can prevent your car from starting. Use a mixture of baking soda and water to clean your battery terminals. Use a wire brush to remove the corrosion carefully.

You can also use a terminal protector spray to prevent corrosion from forming on your battery terminals. This can help keep your battery running smoothly.

Drive Your Car Regularly

If you don’t drive your car regularly, your battery may discharge, and your electrical system may not work correctly. When you drive your car, it charges your battery, and it also keeps the other components in your electrical system working correctly.
