Learning Event 1:
DESCRIBE FUNDAMENTALS OF AUTOMOTIVE BATTERIES
INTRODUCTION
In the first lesson you learned that electricity can be produced magnetically. Electricity is also
produced chemically by means of a battery.
Batteries used in automotive vehicles supply electricity for cranking the engine, igniting the fuel
mixture in the cylinders, and operating most accessories. In fact, cars as they are now designed
could not operate without batteries. Understanding the batteries and knowing how to keep them in
good condition are vital parts of good automotive maintenance. Present-day cars would be quite
helpless and of no use without the electricity furnished by a good battery that is properly connected.
