Battery Charger Controls - Schumacher SE-3002 Owner's Manual

The SE-82-6 and SE-3002 battery charger has a selector switch and an ammeter for reading AMP's. FIGURE 3 shows the charger
controls.
INPUT: 120V AC 60HZ 1.3 AMP
OUTPUT: 6/2 AMP AT 12V DC, 6 AMP AT 6V DC

NOTE: Model SE-3002 meter is similar but, presented in a horizontal format.
CHARGE RATE AND VOLTAGE SWITCH SETTINGS
For 12 volt batteries either 2 or 6 amp charge rate may be se-
lected. For 6 volt batteries, only the 6 amp rate is available. You
may use either the 2 or 6 amp charge rate on large batteries.
For batteries rated 28 ampere hours and less, use the 2 amp
charge rate. The smaller the battery the greater the risk of harm-
ing it by using the 6 amp charge rate.
NOTE: It is important to determine the battery type before charg-
ing. (See BATTERY TYPES)
WARNING: This charger will continue to charge even after the
battery is charged.
WARNING: Overcharging will damage the battery.
This is a manual (non-automatic) battery charger. A Manual
charger will continue to charge and will not shut off. You must
keep a visual check on the ammeter to determine when the
battery is charged.
AMMETER (See FIGURE 4 & 5)
The ammeter gives a reading of the AMP draw by the battery
from the charger. When a fully discharged battery is connected
to the charger, the ammeter will read the maximum output rat-
ing of the charger, either 2 AMPS or 6 AMPS, depending on the
AMP selection. The charge current will gradually taper down as
the battery approaches full charge. As the charge current tapers
down, the ammeter needle will also move down.

PERCENT OF CHARGE
The percent of charge scale in intended as a visual aid to help
simplify reading the state of charge. It is scaled for use with the
6 amp charge rate only. For the 2 amp charge rate use the red
triangle. The percent of charge is based on current drawn by the
battery. For this reason accuracy will vary with the size and bat-
tery type. Typically a 28 ampere hour gel cell battery will draw
less current at end of charge then a 140 ampere hour wet cell
battery. This means that the indication for a fully charged large
battery may be slightly less than 100%.
For the 2 amp charge rate a red triangle has been provided
within the green area of the meter scale, it's accuracy has been
calibrated for use with small batteries. As a battery takes on a
charge, it draws less current from the charger, correspondingly
less of the red area will fall under the meter needle.
