CIRCUIT BREAKER

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 automatically. 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. (See

TROUBLESHOOTING)

BATTERY TYPES

Three basic types of lead-acid batteries can be given a charge with this charger: (1) Conventional and Low Maintenance, (2) Mainte- nance Free, (3) Deep Cycle / Marine.

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.

OPERATING INSTRUCTIONS: CHARGING BATTERY OUT OF THE VEHICLE

When charging battery, take care to determine the battery type. To reduce risk of a spark near battery, follow these steps.

WARNING: A spark near battery may cause battery explosion.

WARNING: When removing battery from vehicle or boat, dis- connect grounded pole first. When disconnecting, make sure the engine/motor and all accessories are off, so as not to cause an arc.

(NOTE: BOAT BATTERIES MUST BE REMOVED AND CHARGED ON SHORE. (TO SAFELY CHARGE ON BOARD REQUIRES SPECIAL EQUIPMENT ESPECIALLY DESIGNED AND UL LISTED FOR MARINE USE. THIS CHARGER IS NOT WATER RESISTANT AND SHOULD NOT BE EXPOSED TO WET CONDITIONS.)

WARNING: When reinstalling battery, attach the ground post first.

1.Check polarity of battery posts. Battery case will be marked by each post: POSITIVE (POS, P, +) and NEGATIVE (NEG, N, -). NOTE: The positive battery post usually has a larger diameter than the negative post.

2.Attach a 24-inch long (or longer) 6-gauge (AWG) insu- lated battery cable to NEGATIVE (NEG, N, -) battery post.

3.Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) post battery. Rock clip back and forth to make good connection.

4.Position yourself and free end of 24 inch cable as far away from battery as possible. Then connect NEGATIVE (BLACK) charger clip to free end of cable. WARNING: Do not face

battery when making final connection. Rock clip back and forth to make a good connection.

FIGURE 7 shows the connection.

5.Plug charger AC cord into 120 volt grounded outlet.

6.Turn switch from off to on.

7.When battery is fully charged, unplug charger from AC power source.

8.When battery is fully charged and charger is unplugged,

(1) remove clip from end of Negative end of cable, and (2) remove clip from Positive battery post, in that order.

9.Clean and store battery charger.
