TESTING THE CHARGING CYCLE
In typical installations, the charger will remain on for up to 12 hours depending on the state of charge of the
batteries when the charge cycle was started.
NOTE: Charging time is limited to 18-hours (max). An error occurs if charging time exceeds 18-hours. See table
on previous page.
A charger could remain on for longer than 12 hours if:
• The vehicle is equipped with batteries larger than 220 Amp hour capacity.
• The charging cycle is interrupted at any time during the charging cycle.
• Defective batteries causing a fluctuating DC voltage that confuses the charger.
• One or more defective cells in the battery pack.
• A brownout (drop in AC line voltage) during the charging cycle.
• An electrically noisy charging environment.
A charger could turn off in less than 12 hours, but still show symptoms of overcharging if:
• The electrolyte in the batteries is too high (boil over).
• The electrolyte in the batteries is too low (excessive gassing or sulfur smell).
To test the charger to see if it is turning off correctly, monitor the battery voltage and charging current during
the charging cycle as indicated below.
Using a digit digital voltmeter and clamp on DC ammeter, monitor the battery voltage and current during the
charging cycle. The charging current should remain within 10% of the DC output current (see previous
page) until the battery voltage reaches 2.55 volts per cell. When the voltage reaches 2.55 volts per cell, the
charging current will drop significantly and slowly taper off (voltage will remain constant). The charger
should turn off within 2 to 4 hours after entering the second stage.
HB/PT AND GEL INDICATOR LAMPS
NOTE: Your charger may not be equipped with these lamps.
HB/PT Lamp
If the HB/PT lamp is “ON”, then the charger has overheated and
has entered a proportionally reduced output. The charging cycle
will terminate if the temperature continues to rise. If the charging
cycle is terminated, the charger will automatically restart once it
has cooled.
The charging cycle is limited to 18-hours. If the HB/PT lamp is
flashing, then the charging time has exceeded 18-hours (time is
limited to 18-hours). If any of the status lamps are flashing, then
the charge cycle did not complete.
GEL lamp
This LED will only be “ON” if the charger is configured for GEL
batteries. Using a GEL charger with non-GEL batteries may result
in an incomplete charge or long charge times.
GEL batteries must be charged with a charger configured for
GEL batteries. Use of any other charger will result in damage
to the batteries and premature failure of the batteries.
