J. OPERATING INSTRUCTIONS
This battery charger is equipped with a self-reseeing circuit breaker. This device protects
the charger from tempory 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.
K. OUTPUT VOLTAGE SELECTOR SWITCH
Set output voltage selector switch to match voltage of battery to be charged. For models
without voltage selector switch make sure voltage of battery matches that of the charger.
Battery charger models having a voltage selector switch are for charging a 6 or 12 volt
battery. Those having no voltage switch are intended for charging a 12 volt battery or
two 6 volt batteries connected in series.
CHARGE RATE SWITCH: Provided on model SE-50 MA-2 only. For smaller batteries, 30
AMP hours (Ah) or less, use only the 2 AMP rate. If time is not a factor, the 2 AMP rate is
also ideal for charging and maintaining larger batteries.
L. This battery charger is equipped with an electronic control circuit which automatically gov-
ern the charge rate to your battery, (except when switch near ammeter is in its left hand
position, marked “MANUAL’ in that position charger will not automatically shut off and user
must guard against overcharging battery).
This charger has optional charging for Low Maintenance/Conventional and Maintenance
Free/Deep Cycle batteries. These chargers employ a selector switch marked correspond-
ingly.
It is important when using this battery charger to determine initially if the battery being charged
is of (1) Maintenance Free/Deep cycle type or (2) Low Maintenance/Conventional type. Re-
fer to section Q for additional information.
Before making any connections to battery, set selector switches for type battery being charged,
read instructions F, G and H carefully.
M. Indication of proper operation to a discharged battery but otherwise in good condition:
1. The amp meter should initially indicate the maximum output ampere rating of the charger.
2. Charge current will gradually taper to approximately one half maximum rating.
During this period the battery is approaching full charge state.
3. As the battery continues to charge the charge rate should taper to approximately 3 amp or
less. Now your battery should be fully charged.
