ASSEMBLY INSTRUCTIONS
Remove the screws from the back of the charger and attach the handle with the screws provided.
21.
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. AH 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: CHARGING
●
SLOW BLINKING RED LIGHT
– Indicates possible weak battery.
●
FAST BLINKING RED LIGHT
– Before charge indicates battery is connected backwards, check connection.
●
CONTINUOUS RED LIGHT
– Indicates AC power is on.
●
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 4 volts the green light will not come on.
●
BLINKING GREEN LIGHT
– Indicates charge is complete, charger in the float mode.
●
CONTINUOUS YELLOW LIGHT
– Indicates charging, bulk charge, less than 80% charged.
●
BLINKING YELLOW LIGHT –
Indicates finish charge, greater than 80% charged.
●
FLASHING GREEN AND YELLOW LIGHTS
– Flooded batteries only, indicates deep discharge recovery process.
NOTES: FOUR SECOND DELAY
- To avoid sparking, the charger tests for correct polarity before applying current to the battery. When
connected properly, the green light will come on for 4 seconds before the yellow light comes on.
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 high voltage levels required for recovery, this program is not included for
sealed batteries.
OPERATING PROCEDURE:
1.
Plug AC cord into outlet. Turn POWER switch ON. RED light will come on.
2.
Select mode of operation Flooded or Sealed/GEL. Most VRLA would be charged with flooded see battery manual for details, if in doubt
charge with sealed.
3.
Connect the RED clamp to the positive (+) and the BLACK clamp to the negative (–). The GREEN light will come on for 4 seconds. See
PREPARING TO CHARGE section under IMPORTANT SAFETY INSTRUCTIONS of this manual.
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 in flooded setting.
6.
Charging will be discontinued if the battery will not accept charge after a reasonable amount of time and the RED light will flash.
7.
Charging time will depend on the size and state of charge of the battery.
8.
When charging is complete, charger will go into a float mode and the GREEN light will blink.
NOTES ON RECOVERY OF DEEPLY DISCHARGED BATTERIES:
a.
Not all deeply discharged batteries can be recovered.
b.
Most weak batteries will be detected while charging. However, some batteries which have been recovered from a deep discharge will
maintain an acceptable open circuit 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.
DEAD BATTERY OVERRIDE
If the battery voltage is below 4V the battery charger will not recognize that it has been connected to a battery. Most batteries even if
completely discharged will recover to a voltage greater than 4V, but if a battery is left in a discharged state for an extended period of time the
voltage may fall below 4V. This charger has been equipped with a Dead Battery Override switch; this can be used to start the charger if the
battery voltage is below 4V.
OPERATION:
a.
Connect the deeply discharged battery to charger, battery should be placed as far away from the charger as the cables will allow. (see
Section 18). Please insure that the battery is connected with the correct polarity.
b.
Press and hold the override switch; green LED should light, if monitoring the battery voltage should see it rise.
CAUTION: Never press the override switch without a battery connected.
c.
After several seconds release the override switch, if the battery will accept a charge it should now start charging. For best results the
Battery Type switch should be set for flooded. If the battery is a sealed type; the Battery Type switch can be changed after the battery
has reached the gassing point (Yellow Led starts to flash).
d.
The battery may have to be connected to the charger several times before the charger will not fail the battery as a bad battery (Red Led
Flashing).
NOTE: The operator should only need to press the override for the first attempt to recover the battery.
