4. After selecting battery type, determine the cor-
rect charge rate for your particular battery. Small
batteries (< 10 AH) should be charged at the 2
Amp setting rate. Larger types (10-30 AH) such as
used in motorcycles, PWC, etc. are best charged
at the 4 Amp rate setting. For batteries whose
capacity rating is greater than 30AH or a fast
recharge is needed set charger to the 8 Amp rate.
If unsure or recharge time is not important, always
choose a low setting (2 or 4 Amp).
Note: The safest procedure is to choose the low-
est possible setting when in doubt or recharge
time is not important, as there may be conditions
such as an internally damaged battery that cannot
be reliably detected.
5. After selecting both battery type and charge
rate, plug the unit’s Power cord into a standard –
grounded 120 Vac electrical outlet. The Power ON
LED Indicator will light GREEN. If it does not light
GREEN check the outlet to be sure it is function-
ing. In addition, be sure if outlet is controlled by a
switch, no one will accidentally shut off the power
to the outlet. Check for correct polarity = (no
ERROR RED LED Indicator). If ERROR Indicator is
lit, reverse the charger’s output connections to the
battery.
6. Press the Stop/Restart button. The Charge
– Float LED Indicator will light GREEN. The charger
will now begin charging by first checking the bat-
tery to determine its voltage and ability to accept a
charge. Should the battery not have a normal fully
discharged voltage (10.5-V minimum) the unit will
begin charging in the “Soft-Start” mode to deter-
mine if the battery can be safely charged. If it can-
not, the Power ON – Error LED will flash RED and
charging will be stopped. Battery should be care-
fully checked under a load by a qualified person
before further attempting to charge it.
