6H-2 CHARGING SYSTEM
BATTERY
GENERAL DESCRIPTION
The battery has three major functions in the electrical system.
D It is a source of electrical energy for cranking the engine.
D It acts as a voltage stabilizer for the electrical system.
D It can, for a limited time, provide energy when the electrical load
exceeds the output of the generator.
CARRIER AND HOLD-DOWN
The battery carrier should be in good condition so that it will support
the battery securely and keep it level.
Before installing the battery, the battery carrier and hold-down
clamp should be clean and free from corrosion and make certain
there are no parts in carrier.
To prevent the battery from shaking in its carrier, the hold-down
bolts should be tight enough but not over-tightened.
ELECTROLYTE FREEZING
The freezing point of electrolyte depends on its specific gravity.
Since freezing may ruin a battery, it should be protected against
freezing by keeping it in a fully charged condition. If a battery is fro-
zen accidentally, it should not be charged until it is warmed.
SULFATION
If the battery is allowed to stand for a long period in discharged
condition, the lead sulfate becomes converted into a hard, crystal-
line substance, which will not easily turn back to the active material
again during the subsequent recharging. "Sulfation" means the re-
sult as well as the process of that reaction.
Such a battery can be revived by very slow charging and may be
restored to usable condition but its capacity is lower than before.
