6. Connect charger AC supply cord to a mains electric outlet.
7. When disconnecting the charger, always do so in sequence of connecting procedure and
break rst connection while standing as far away from battery as practical.
NOTE: A marine (boat) battery must be removed and charged on shore. To charge it on a boat
requires equipment specially designed for marine use.
OPERATING INSTRUCTIONS
AUTOMATIC OPERATION - Your new battery charger is completely automatic and can be left
plugged into mains power. The charger output depends on the condition of the battery it is
charging. When the battery is fully charged, the display will indicate “good” and show battery
level at 100%. The charger will switch itself to a storage charge mode. It will automatically
monitor and maintain the battery at full charge.
CABLE CONNECTIONS - Your new battery charger is equipped with two output leads, a
red positive lead, and a black negative clip lead. Plus an eyelet lead suitable for permanent
connection to battery terminals. Always connect or disconnect the output leads before
plugging into AC power.
For all battery types: Connect the red positive (+) lead to the positive terminal of the battery.
Connect the black negative (-) lead to the negative terminal of the battery.
Note: If the charger is left connected to a lead acid battery for long periods of time, check
water levels periodically as directed by the battery manufacturer to ensure electrolyte is
maintained at a proper level.
ATTENTION: THE BATTERY CHARGER HAS SPARK FREE, POLARITY & SHORT CIRCUIT
PROTECTION BUILT IN. HOWEVER AS GOOD PRACTICE NEVER ALLOW THE TWO CLIPS
TOUCH EACH OTHER. CHARGE ONLY ONE BATTERY AT A TIME.

MINIMUM VOLTAGE - The charger will not produce voltage (turn on) until it recognizes at
least three volts from the battery. The battery charger clips must be clipped to a battery in the
correct polarity to initiate output voltage and begin charging when in lead acid (Pb) charge
mode.
When in Lead Acid (Pb) charge mode if the charger is hooked up in reverse polarity, the Fault
symbol will turn on indicating that the connection has been made in reverse of the polarity of
the battery and a charge has not been initiated.
Clips must be re-connected in the proper polarity to start the charger, Red to Positive (+ to +)
and Black to Negative (- to -).
NOTE: DO NOT TURN YOUR BATTERY CHARGER ON AND OFF REPEATEDLY (Plug and Unplug)
WITHIN A SHORT PERIOD. IF THIS HAPPENS, UNPLUG BATTERY CHARGER FROM AC POWER,
WAIT FOR ONE MINUTE AND THEN CONNECT THE CHARGER AGAIN.
ESTIMATED TIME TO CHARGE
To calculate your approximate time to complete charging your battery use the following
formula:
Battery Capacity ÷ Charger Current = Hours to charge.
or
Amp Hours (Ah) ÷ Amps = Hours to charge.
For example you if you have a 60Ah battery and the charger delivers 4.5A current, you can
nd the number of hours by dividing 60 by 4.5 = 13.3 hours.
If you have a high capacity battery it can take more than 24 hours to reach full capacity. For
faster charging, purchase a higher current output charger.
FULLY DISCHARGED BATTERIES - Lead Acid (Pb) Charge Mode:
If your battery is totally discharged (below 2 volts), the charger circuitry will not start due to its
internal safety circuit. The internal safety circuit of the battery charger must sense more than
2 volts in the battery before it will allow the charging circuit to turn on. In this case (battery
voltage between 0.5V-2.0V) the Fault symbol will ash, which means charging has not been in
initiated. If the battery voltage is less than 0.5V, the charger will be return to standby mode.
Note: Unless the battery was rapidly discharged most 12 Volt lead acid batteries that retain a
state of charge of less than 9 volts are likely to be worn out or defective.
72-HOUR SAFETY FEATURE
A 72 hour safety timer will commence anytime the charger is on. This feature is designed to
protect marginal batteries from over charging. If the battery voltage reaches the proper level
within 72 hours. the charger will automatically switch to maintenance mode. If your battery is

marginal defective, the battery charger will stop all the charging processes in order to protect
the marginal battery from over charging. Please check battery condition as it could also
indicate that a very large (high capacity) battery in good condition that is not yet fully charged.
When this happens, the display will show “BAD BAT”.
