5. Charger will automatically start within 15 - 30 seconds. The Charge
– Float LED Indicator will light GREEN. The charger will now begin
charging by first checking the battery to determine its voltage and
ability to accept a charge. Should the battery not have a normal
fully discharged voltage (10.5V minimum) the unit will begin charging
in the “Soft-Start” mode to determine if the battery can be safely
charged. If it cannot, the Power On – Error LED will flash RED and
charging will be stopped. Battery should be carefully checked under
a load by a qualified person before further attempting to charge it.
Note : If the battery does not have a minimum no
load OCV (Open Circuit Voltage) of 3 volts, the ERROR
LED will light RED and charger will reject battery.
No further effort should be made to charge this battery with this
charger or any charger. Discard this battery, unless it has just
been subjected to a long period of continuous discharge under
a load such as can occur with leaving lights on or cranking an
engine excessively. Allow such a battery to “Rest” for several
hours (overnight if possible) before determining if it is defective.
Be very suspicious of any 12-V battery that does not have at least 11
Volts (OCV) before it is recharged. It may well be seriously damaged
and unsafe for any type of use or recharge. The unit’s Battery
Condition Indication
LED will help you
determine if battery
is less than 11 Volts
( YELLOW) or greater
than 11 Volts ( GREEN).
6. After battery has
been fully charged, the
GREEN Charge-Float
LED Indicator will begin
blinking. It will continue
to blink indefinitely,
unless unit is disconnected from battery. Should battery be unable
to be fully charged, the LED will not blink and the RED Error LED
will blink. Battery may not be able to be fully charged, may be too
