SWITCHES
The SE-1012D has one charge rate only . The switch on this unit is for selecting the charging voltage, either 6 volt or 12 volt. Match the charging voltage to the
battery being charged.
The SE-1052, SE-1010-2 and the SE-1250 models are 12 volt only and must not be used on 6 volt batteries. The switches on these chargers are for selecting
the charging rates (amps) desired for your application. Use the 2 amp rate feature offered on some models to charge smaller batteries such as those on
motorcycles, snowmobiles, etc. Use the 10 amp rate to charge larger automotive batteries. On the SE-1250, the 30 amp boost and the 50 amp start position is
in the same location. Make sure you follow the duty cycle shown on the front of the charger when using these positions. To obtain the 50 amps start simply turn
the ignition key on the vehicle. Models SE-1052 and SE-1250 have Engine Start.
TIMER
The 12 hour timer on SE-1012D is useful for preventing overcharging of the battery. Set the pointer knob to the number of hours you want the
charger to be on. The knob will automatically rotate counter clockwise indicating the remaining charge time. When the knob reaches the OFF
position, the charger will shut off. When the HOLD position is selected, the charger will remain on indefinitely. Familiarize yourself with the action
of these settings by rotating the knob through each position several times.

BATTERY TYPES
This battery charger is equipped with a self-resetting circuit
breaker. This device protects the charger from temporary over-
loads. In the event of an overload, the circuit breaker will trip
open and after a short cooling off period will reset automati-
cally. This process is known as cycling and can be recognized
by an audible clicking sound.
NOTE: Clicking sound is normal. Wait until charger automati-
cally resets itself.
CAUTION: Persistent clicking (more than 30 minutes) may in-
dicate reverse connection or shorted battery cells.
Three basic types of lead-acid batteries can be given a charge with this charger: (1 ) Conventional and Low Maintenance,
(2) Maintenance Free, (3) Deep Cycle.
Conventional and Low Maintenance Batteries. These are the
antimony/lead batteries. Conventional/Low Maintenance batter-
ies require periodic addition of water to the acid solution (elec-
trolyte). Additional water may be added by removing the filler
caps located on the top of the battery.
IMPORTANT: When antimony is known to be one of the mate-
rials used in the battery's construction, that battery is a Low
Maintenance/Conventional type.
CAUTION: Some Low Maintenance batteries have a relatively
smooth top without any apparent battery filler caps. If, however,
the battery manufacturer/distributor recommends periodic check-
ing of electrolyte level and provides access to the battery for
water additions, the battery is probably a Low Maintenance/
Conventional type.
Maintenance Free Batteries. These are calcium/lead batteries
and normally do not require water additions. Therefore, filler
caps have been removed from the battery surface. These bat-
teries will have a smooth or sealed appearance.
Deep Cycle Batteries. These heavy duty batteries are used in
boats, construction equipment, sump pumps, etc. They are nor-
mally marked DEEP CYCLE on the outside of the case.
