A battery works by storing electrical energy from the alternator as chemical energy. This chemical energy is reconverted on demand from the electrical system.

It develops voltage from the chemical reaction produced when two dissimilar metals such as the positive and negative plates, are immersed in the electrolyte, a solution of sulphuric acid and water. In a typical starter battery the voltage is approximately 2 volts per cell, for a total of 12 volts. Electricity flows from the battery as soon as there is a circuit between the positive and negative terminals.

  1. Keep the vent caps on
  2. Don’t allow smoking, open flames or sparks near the battery
  3. Don’t allow the battery to become hot to the touch.

  1. Maintain water level
    If your battery has removable vent caps, you should re-check the water level and add water when it is low.
  2. Keep terminals clean.
    Visually inspect the terminals and cables at least once a year especially in hot temperatures for signs of corrosion.
