Starting And Charging
How does a car’s Starting System work?
The starting system is composed of an electric starter motor and a starter solenoid. The starter solenoid is the electrical switch, activated by the ignition system when you turn the key, which engages the starter motor. The starter motor essentially spins the engine a few times so the combustion process can begin.
How does a car’s Charging System work?
The automobile’s charging system consists of three primary components; the battery, alternator and the voltage regulator. The battery supplies electrical power for your vehicle while starting and during periods of high electrical loads. It also acts as a shock absorber for the electrical system by smoothing out any voltage spikes before they get to the computer.
The alternator and voltage regulator provides power to the vehicle while the engine is running and maintains the batteries charge. The voltage regulator monitors the battery’s state of charge and directs the alternator to recharge the battery as necessary.
What effect does extreme cold have on my battery?
Cold temperatures severely reduce the effectiveness of chemical reactions within the battery and increase the battery’s internal resistance. As the temperature drops, so does the battery’s cranking power. Cars also require additional cranking power in cold weather since the motor oil is thicker, making the engine harder to turn over. Weak batteries are also susceptible to freezing, which damages internal components and containers.
What effect does extreme heat have on my battery?
Heat is the primary cause of battery failure. Heat causes the water in the battery’s electrolyte to evaporate and causes the positive plate grids to corrode more rapidly.
How often should I replace my battery?
Battery life varies from vehicle to vehicle and is based on a variety of factors. They are manufactured to last anywhere from two to five years, but exposure to heat, vibration and malfunctioning components of your vehicle’s electrical system can shorten the batteries useful life.
