OVERVIEW AND OPERATION PROCESS
1. DESCRIPTION AND OPERATION
1) Battey
The sealed battery is standard on all cars. There are no vent plugs in the cover.
The battery is completely sealed, except for two small vent holes in the sides.
These vent holes allow the small amount of gas produced in the battery to escape.
The battery has the following advantages over conventional batteries:
No water addition for the life of the battery.
·
Overcharge protection. If too much voltage is applied to the battery, it will not accept as
·
much current as a conventional battery.
In a conventional battery, the excess voltage will still try to charge the battery, leading
to gassing, which causes liquid loss.
Not as liable to self-discharge as a conventional battery. This is particularly important when
·
a battery is left standing for long periods of time.
More power available in a lighter, smaller case.
·
The battery has three major functions in the electrical system.
First, the battery provides a source of energy for cranking the engine.
Second, the battery acts as a voltage stabilizer for the electrical system. Finally, the battery
can, for a limited time, provide energy when the electrical demand exceeds the output of the
generator.
2) Ratings
▶
A battery has two ratings: (1) a reserve capacity rating designated at 27°C(80°F),
which is the time a fully charged battery will provide 25 amperes of current flow at or above
10.5 volts (2) a cold cranking amp rating determined under testing at -18°C(0°F),
which indicates the cranking load capacity.
(1)Reserve Capacity
The reserve capacity (RC) is the maximum length of time it is possible to travel at night with the
minimum electrical load and no generator output. Expressed in minutes, the RC rating is the
time required for a fully charged battery, at a temperature of 27°C(80°F) and being
discharged at a current of 25 amperes, to reach a terminal voltage of 10.5 volts.
