A SPARK NEAR THE BATTERY MAY CAUSE BATTERY EXPLO-
SION. 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.

H. 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.
I. OPERATION INSTRUCTIONS
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.
J. OUTPUT VOLTAGE
This charger is for use with 12 volt lead-acid batteries. The SE-70MA is for 12 and 24 volt systems.
10 Amp 12 Volt setting: The initial charge current should be 10 amps gradually tapering throughout the charge cycle to 5 amps. Though
not indicated, battery voltage will gradually rise to approximately 14.3 volts, then hold constant throughout remainder of charge cycle.
When the battery reaches 14.3 volts and charge current drops to 5 amps the charger will turn off. Initially the battery voltage will drop from
its 14.3 volt level fairly quickly. When 13 volts is reached, the charger will again turn on, until the 14.3 volt, 5 amp condition is met. As this
action continues, on time will decrease to a few seconds while off time increases to a range of several minutes to an hour. on/off times
vary with size, type and condition of battery.
