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.

(2) Cold Cranking Amperage

The cold cranking amperage test is expressed at a battery temperature of -18°C(0°F). 

The current rating is the minimum amperage, which must be maintained by the battery for 30 seconds at 

the specified temperature, while meeting a minimum voltage requirement of 7.2 volts.

This rating is a measure of cold cranking capacity.

The battery is not designed to last indefinitely. However, with proper care, the battery will provide many 

years of service. If the battery tests well, but fails to perform satisfactorily in service for no apparent 

reason, the following factors may point to the cause of the trouble:

Vehicle accessories are left on overnight.

Slow average driving speeds are used for short periods.

The vehicle's electrical load is more than the generator output, particularly with the addition of 

aftermarket equipment.

Defects in the charging system, such as electrical shorts, a slipping generator belt, a faulty generator, 

or a faulty voltage regulator.

Battery abuse, including failure to keep the battery cable terminals clean and tight or a loose battery 

hold-down clamp.

Mechanical problems in the electrical system, such as shorted or pinched wires.

3) Charging Time Required

The time required to charge a battery will vary depending upon the following factors:

Size of Battery - A Completely discharged large heavy-duty battery required more than twice the 

recharging time as a completely discharged small passenger car battery.

▶

Temperature - A longer time will be needed to charge any battery at -18°C(0°F) than at 
27°C(80°F). 

When a fast charger is connected to a cold battery, the current accepted by the battery will be very 

low at first. 

The battery will accept a higher current rate as the battery warms.

▶

Charger Capacity - A charger which can supply only 5 amperes will require a much longer charging 

period than a charger that can supply 30 amperes or more.

▶

State-of-Charge - A completely discharged battery requires more than twice as much charge as a 

onehalf charged battery. 

Because the electrolyte is nearly pure water and a poor conductor in a completely discharged 

battery, the current accepted by the battery is very low at first. Later, as the charging current causes 

the electrolyte acid content to increase, the charging current will likewise increase.

4) Charging a Completely Discharged Battery (Off the Vehicle)

Unless this procedure is properly followed, a perfectly good battery may be needlessly replaced. 

The following procedure should be used to recharge a completely discharged battery:

Measure the voltage at the battery terminals with an accurate voltmeter. 

If the reading is below 10 volts, the charge current will be very low, and it could take some

time before the battery accepts the current in excess of a few milliamperes. 

Refer to "Charging Time Required" in this section, which focuses on the factors affecting both the 

charging time required. Such low current may not be detectable on ammeters available in the field.

Set the battery charger on the high setting.

Continue to charge the battery until the charge current is measurable. Battery chargers vary in the 

amount of voltage and current provided. The time required for the battery to accept a measurable 

charger current at various voltages may be as follows:

3.

If the charge current is not measurable at the end of the above charging times, the battery 

should be replaced.

If the charge current is measurable during the charging time, the battery is good, and charging 

should be completed in the normal manner.

·

·

If the charge current is still not measurable after using the charging time calculated by the above 

method, the battery should be replaced.

·

It is important to remember that a completely discharged battery must be recharged for a sufficient 

number of ampere hours (AH) to restore the battery to a usable state.
