This battery charger is 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.
Three basic types of lead-acid batteries can be given a charge with this charger: (1) Conventional and Low Maintenance, (2)
Conventional and Low Maintenance Batteries. These are the
antimony/lead batteries. Conventional/Low Maintenance bat-
teries require periodic addition of water to the acid solution
(electrolyte). 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 materi-
als used in the battery's construction, that battery is a Low Main-
tenance/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
checking of electrolyte level and provides access to the battery
OPERATING INSTRUCTIONS: CHARGING BATTERY IN VEHICLE
When charging battery in the vehicle, take care to determine the battery type and which post is grounded. To reduce risk of a spark
near battery, follow these steps when battery is installed in vehicle. WARNING: A spark near battery may cause battery explosion.
1. Position AC power cord and DC charging cords to reduce
risk of damage by hood, door, or moving engine parts.
2. Stay clear of fan blades, belts, pulleys, and other parts
that can cause injury.
3. Check polarity of battery posts. Battery case will be
marked by each post: POSITIVE (POS, P, +) and NEGA-
READING AMMETER:
6 AMP SETTING: When fully charged on the 6 AMP setting,
needle will indicate between 2 and 3 amps, as shown in

NOTE: Clicking sound is normal. Wait until charger automati-
cally resets itself.
CAUTION: Persistent clicking (more than 30 minutes) may indi-
cate reverse connection or shorted battery cells. (See
TROUBLESHOOTING)

BATTERY TYPES

Maintenance Free, (3) Deep Cycle.
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.

TIVE (NEG, N, -). NOTE: The positive battery post usually
has a larger diameter than the negative post.
Determine which post of battery is ground (connected) to
chassis.
NOTE: The negative post is normally grounded.
