20. CHARGE PERIOD
The approximate required time to bring a battery to full charge state depends upon the number of ampere-hours (AH) depleted
from the battery. AHs are determined by multiplying the number of hours times the number of Amps supplied by a battery to a load
and normally indicated on the battery. For example - if a load was connected to a battery, which drew 7 Amps for a period of 5
hours, the battery will have supplied 35 AH. The approximate recharge time would then be calculated by dividing the 35 AH
depleted from the battery, by the ampere charge rate of the charger. To allow for tapering of the charge rate add 25 percent to the
charge time.
OPERATING INSTRUCTIONS
* CONTINUOUS RED LIGHT - Indicates AC power is on.
* FLASHING RED LIGHT – Weak Battery.
* CONTINUOUS GREEN LIGHT - Indicates correct connection. If when battery is connected, the green light does not light,
check for proper polarity or poor connections. If the battery voltage is below 2 volts the green light will not come on.
* CONTINUOUS YELLOW LIGHT - Indicates charging.
* BLINKING YELLOW LIGHT - Indicates battery is near end of charge and is in the finish charge mode.
* BLINKING GREEN LIGHT - Indicates charging is complete and is in the float mode.
* FLASHING GREEN AND YELLOW LIGHTS - Indicates first stage of deep discharge recovery process.
NOTES:
FIVE SECOND DELAY - To avoid sparking, the charger control tests for correct polarity before applying current to the battery.
When connected properly, the green light will come on for 5 seconds before the yellow light comes on.
BATTERY TEST - During the 5 second period when the green light is on, the charger will test for a deep discharged battery.
BATTERY CHARGE - After testing the battery, the control will select a charging rate suitable for the voltage and state of charge of
the battery. A small battery, or a nearly charged battery will cause the charger to rapidly step down in current to avoid heating and
gassing.
FINISH CHARGE - In order to reach a 100 % state of charge on the battery, a finish charge cycle has been programmed into the
charger. During the finish cycle, the yellow light will blink. If the battery is good, there will be enough charge in the battery at this
time to start a vehicle when the yellow light is blinking. If desired, the battery can be removed and replaced in the vehicle. The
vehicle’s alternator will finish charging the battery.
NOTE: To avoid sparking, always turn off power switch to disconnect charger power.
BATTERY MAINTAINER – After charge is complete the charger will go to a float charge to maintain battery.
DEEP DISCHARGE RECOVERY - If the charger determines a battery is deeply discharged, it will attempt to recover the battery
with a program designed to enhance charge acceptance. Because of the voltage levels required for recovery, this program is not
included for sealed batteries.
OPERATING PROCEDURE:
1. Turn on Power Switch. The Red light should come on.
2. Select Battery Type.
3. Connect the POSITIVE (RED) clamp to the positive (+) terminal of the battery. Connect the NEGATIVE clamp to the
negative (-) terminal of the battery. The GREEN light will come on for about 5 seconds.
4. The YELLOW light will come on when the GREEN light goes off and charging will begin.
5. If the battery is deeply discharged, the YELLOW and GREEN lights will flash on and off for up to 30 minutes.
6. The battery is between 80% and 99% state of charge when the YELLOW light blinks. The charger is in the finish charge
mode.
7. The battery has been fully charged when the GREEN light is blinking. The charger maintains battery at a float voltage.
NOTES:
a. If the charger is connected to a fully charged battery the charger will go into the finish charge mode then shut off and the
GREEN light will blink.
b. Not all deeply discharged batteries can be recovered.
c. Some batteries which have been recovered from a deep discharge will maintain an acceptable open circuit terminal voltage but
have a reduced capacity under load. Always load test or otherwise test a recovered battery to determine if the CCA capacity is
within 80% of the rated value.
d. Any time a malfunction is suspected reset the control by turning AC Switch on and off.
