Meter And Switch Functions - Schumacher SE-2150MA Owner's Manual

D.
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, 110 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.
