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:
1. 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.
2. Set the battery charger on the high setting.
Some chargers feature polarity protection circuitry, which prevents charger unless the
charger leads are correctly connected to the battery terminals.
A completely discharged battery may not have enough voltage to activate this circuitry, even
though the leads are connected properly, making it appear that the battery will not accept
charging current.
Therefore, follow the specific charger manufacturer's instruction for by passing or
overriding the circuitry so that the charger will turn on and charge a low-voltage battery.
3. 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:
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.
· 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.
If the charge current is still not measurable after using the charging time calculated by
·
the above method, the battery should be replaced.
