As we place more demands on batteries and electrical systems with anti-theft devices, cell phones and audio systems, it's even more important to pay attention to battery selection and care.

Maintenance:

• Have your battery and charging system inspected yearly. Early detection of a weak component can save time and money.

Before replacing a battery:

• Check the battery, electrical and vehicle-charging system for problems. Signs of a weak battery are slow engine cranking, dim headlights and illumination of the battery/charging system warning light.
• Clear corrosion from the battery. Terminal connections and the battery hold-down that secures the battery can be cleaned with a stiff brush and a baking soda and water solution. Rinse the battery with water, but be careful of staining the driveway.
• Check the electrolyte level if the battery has removable vent caps. The fluid should be above the tops of the plates inside the battery. If fluid is needed, add distilled water, but do not overfill. Most newer batteries are sealed and do not require water replacement.
• Make sure battery terminal connections are tight. Adjust loose fittings or replace fittings that have cracked.

When jump-starting a car:

• Take safety precautions. Always wear proper eye protection and gloves when working around batteries. Never smoke or work near an open flame. Hydrogen gas is present and may explode.
• Check the owner's manual for instructions. Jump-starting can be dangerous. Motorists who are uncertain about battery maintenance should seek help from a certified technician or road service provider.

Selecting a battery:

• Choose a battery of the same physical size as the original. This will avoid excessive vibration or movement.
• Never install a battery that is below the vehicle manufacturer's recommended rating.
