Automotive Battery Vocab exercise

An Ampere (A) is a unit used for measuring what in the context of electric current?

• Voltage

• Resistance

• Electric current

• Power

Cold Cranking Amps (CCA) measure the ability of a battery to:

• Start an engine in cold temperatures

• Provide power for a long duration

• Charge quickly

• Resist corrosion

Reserve Capacity (RC) in terms of battery performance is defined as:

• The amount of time a fully charged battery can deliver a constant current of 25 amps at 80°F before the voltage falls below 10.5 volts.

• The total energy capacity of a battery measured in watt-hours.

• The maximum current a battery can deliver in a short burst.

• The lifespan of a battery under normal usage conditions.

Amp-Hour (Ah) indicates about a battery's capacity:

• The voltage of the battery

• The energy stored in the battery

• The current the battery can provide for one hour

• The lifespan of the battery
