A strong, healthy battery is essential to the proper operation of your vehicle. A battery can last four to five years with proper care, although battery failure can occur in as little as three years in hot climates. Premature battery failure can occur as a result of chronic undercharging, overcharging, abuse, or vibration. Since modern vehicle computer systems create a small but constant drain on batteries, even when the vehicle is parked, long sitting periods can cause a vehicle's battery to go dead and need a charge.
