1. These battery chargers are equipped with a self-resetting
circuit breaker. This device protects the charger from
temporary overloads. In the event of an overload, the circuit
breaker will trip open, and after a short cooling off period
will reset automatically. this process is known as cycling
and can be recognized by an audible clicking sound.
2. These battery chargers are equipped with an electronic
control circuit which automatically governs the charge rate
to your battery. The charger will satisfactorily charge
Maintenance Free and Conventional batteries.

I. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE
A SPARK NEAR THE BATTERY MAY CAUSE BATTERY EX-
PLOSION. TO REDUCE RISK Of A SPARK NEAR BATTERY:
1. Check polarity of battery posts. POSITIVE (POS, P,+) battery
post usually has a larger diameter than NEGATIVE (NEG,
N, -) post.
2. Attach at least a 24-inch-long 6-gauge (AWG) insulated
battery cable to NEGATIVE (NEG, N, -) battery post ( not
provided).
3. Connect POSITIVE (RED) charger clamp to POSITIVE
(POS, P,+) post of battery.
4. Position yourself and free end of cable as far away from
battery as possible - then connect NEGATIVE (BLACK)
charger clamp to free end of cable.
5. Do not face battery when making final connection.
6. When disconnecting charger, always do so in reverse
sequence of connecting procedure and break first
connection while as far away from battery as practical.
7. A marine (boat) battery must be removed and charged on
shore. To charge a battery on the boat requires equipment
specially designed for marine use.
J. AC POWER CORD CONNECTION INSTRUCTIONS
DANGER - Never alter AC cord or plug provided - if it will not fit outlet, have proper outlet installed by a qualified electrician. Improper
connection can result in a risk of an electric shock.
This battery charger is for use on a nominal 120-volt 60 HZ circuit.
K. OPERATION INSTRUCTIONS
L. OUTPUT VOLTAGE
M. CHARGE RATE SWITCH
These chargers are for use with 12 volt lead-acid batteries only except for the SF-125A.
For smaller batteries, 30 AH (ampere hour) or less, use 2 AMP setting. Small batteries may not be able to accept the potential of the 10
AMP setting. Unconverted energy will result in excess heat which the battery may not be able to dissipate, thus resulting in damage to
the battery.
For larger batteries either setting may be used.
