How Does it Work?
- A battery stores energy in chemical form that can be released on demand as electricity.
- This electrical power is used by the car’s ignition system for cranking the engine.
- Should the alternator or accessory drive belt fail, the battery might also need to power the vehicle’s entire electrical system for a short period of time.
How Is It Made?
- Car batteries are made up of alternating negative and positive plates of lead and separators.
- Plates are bundled to produce about 2.2 volts and inserted into cells in the case.
- Cells are tied together by a strap of which one end forms the positive battery terminal and the other, the negative.
- These plates are submerged into an electrolyte solution of sulfuric acid and water.
Why Does It Fail?
- Old age.
- Heat, cold and vibration.
- Elements in the electrical system that drain your battery.
- Leaving your headlights, radio, etc on when your car isn’t running.
What are Symptoms of Failure?
- Slow engine crank.
- Issues with electrical components.
- Dashboard warning light.
- Swollen battery case.
- Old age.
- Weird smell.
What Are the Consequences of Failure?
- Most frequently, the vehicle will fail to start.
- Conventional car batteries last 3-4 years, much shorter in hot climates and those with poor road-quality.
