D. METER AND SWITCH FUNCTIONS

BATTERY TYPE: You may select between two basic Battery

Types: Regular or Deep Cycle Battery. Both settings operate automatically and will shut off when the battery is fully charged. Use the Regular for all wet-cell, lead-acid batteries. (This charger is not recommended for Gel-Cell and AGM batteries.) Use the Deep Cycle setting for all Deep Cycle wet-cell, lead-acid batter- ies. How can you tell your battery type? Deep Cycle batteries are usually marked as such. If not, the battery will fall under the category of "Regular" batteries. Most automotive batteries are considered "Regular" batteries.

Some Deep Cycle batteries are designed in a way that charging them in the Regular setting is more suitable. When charging a Deep Cycle battery, if the Full Charge indicator lamp does not become illuminated after a 12-hour charge period and the charge current as indicated by the Amp Meter is less than 8 amps, move the switch to the Regular setting. If the Full Charge indi- cator lamp still remains off after charging, you should discon- nect the charger and have both the battery and charger profes- sionally tested.

6 VOLT, 15 AMP: Used for charging medium and large size wet-cell, lead-acid 6 volt batteries. Do not charge small batter- ies such as used in motorcycles, lawn and garden equipment. (Manual Operation. Monitor frequently while charging a battery.)

12 VOLT, 2 AMP: The 2 amp automatic charge rate is recom- mended for charging small batteries and warming large ones. If used for maintaining the Full Charge level of larger batteries, limit the charge period to a few days at a time. (Automatic Op- eration.)

12 VOLT, 15 AMP: Used for charging medium and large size wet-cell, lead-acid, 12-volt batteries. (Automatic Operation.)

12 VOLT, 100 AMP ENGINE START: Used for crank starting of 12 volt vehicles. The Engine Start position should not be used for battery charging, doing so will cause the charger to overheat and then protect itself by cycling off and on. (Manual Opera- tion.)

METER: The meter indicates the amount of current measured in amperes that is being drawn from the charger by a battery. In the 15 amp charge rate a typical discharged battery may ini- tially draw more than 15 amps during the first few minutes of charge. As the battery continues to charge current should gradu- ally taper to within 6 to 8 amps at full charge.

The START area of the meter is reserved to indicate when a high rate of current is being drawn from the charger. It is normal for the meter pointer to be in this area while cranking a vehicle.

When using the 2 amp charge rate the meter may indicate some activity but doesn’t have the resolution to accurately display the battery’s state of charge. For this reason you should depend on the full charge light indicator.
