CIRCUIT BREAKER

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.

NOTE: Clicking sound is normal. Wait until charger automatically resets itself.

CAUTION: Persistent clicking (more than 30 minutes) may indi- cate reverse connection or shorted battery cells. (See TROUBLE-

SHOOTING)

BATTERY TYPES

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 / Marine.

Conventional and Low Maintenance Batteries. These are the antimony/lead batteries. Conventional/Low Maintenance batteries 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 materials used in the battery's construction, that battery is a Low Mainte- nance/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 for water additions, the battery is probably a Low Maintenance/Conven- tional 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 batteries 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 out of the vehicle, take care to determine the battery type. To reduce risk of a spark near battery, follow these steps when battery is outside vehicle. WARNING: A spark near battery may cause battery explosion. WARNING: When removing battery from vehicle or boat, disconnect grounded pole first. When disconnecting, make sure all accessories are off, so as not to cause an arc. (NOTE: A marine (boat) battery must be removed and charged on shore. (To charge on board requires special equipment designed for marine use.) WARNING: When reinstalling battery, attach the ground post first.
