WARNING
IF THE BATTERY REMAINS INSTALLED IN THE VEHICLE:
1.
DO NOT CONNECT THE CHARGER AC POWER PLUG TO THE
ELECTRICAL OUTLET UNTIL ALL OTHER CONNECTIONS ARE MADE!
2.
Place both the AC and DC power cords in the best position to avoid
accidental damage by movable vehicle parts, i.e. hoods, doors, or moving
engine parts (fan blades, belts, or pulleys).
3.
Check the polarity of the battery posts. If the positive (pos, p, +) post is
connected to the vehicle chassis, then the vehicle has a positive ground
system. If the negative (neg, n, -) post is connected to the vehicle chassis,
then the vehicle has a negative ground system. Negative ground systems
are the most common.
4. For negative ground systems, connect the positive (red) alligator clip, or
ring terminal to the positive battery post. Then connect the negative
(black) alligator clip, or ring terminal to the vehicle chassis. Do not make
the negative charger clip or ring connection to the carburetor, fuel lines, or
thin, sheet metal parts. Make that connection to the engine block or a
heavy gauge metal part of the frame.
5. For positive ground systems, connect the negative (black) alligator clip, or
ring terminal to the negative battery post. Then connect the positive (red)
alligator clip, or ring terminal to the vehicle chassis. Do not make the
positive charger clip or ring connection to the carburetor, fuel lines, or thin,
sheet metal parts. Make that connection to the engine block or a heavy
gauge metal part of the frame.
6. Connect the AC power plug to the electrical outlet.
ADDITIONAL CHARGER INFORMATION
AUTOMATIC CHARGING AND BATTERY STATUS
MONITORING:
The
WATERPROOF
DELTRAN BATTERY TENDER®
International Battery Chargers are completely automatic and may be left
connected to both AC power and to the battery that it is charging for long
periods of time. However, it is prudent to periodically check both the battery
and the charger for normal operation during these extended charging periods.
The charger output power, voltage, and current all depend on the condition of
the battery that is being charged. Both
WATERPROOF
DELTRAN BATTERY
TENDER® International Battery Chargers have 2 status lights (one amber, and
one green) that indicate the operating mode of the charger, and the condition
of the battery that is connected to the charger.
The charger operates in one of the 3 primary charge modes: the bulk mode
(full charge power, constant current, increasing battery voltage, battery is 0%
to 75% or 80% charged), the absorption mode (high constant voltage,
decreasing current, battery is 75% to 100% charged), or the storage/float
maintenance mode (low constant voltage, minimal charge current, battery is
100% to 103% charged).
When the battery is fully charged, the green status indicator light will turn on
and the charger will switch to a storage/maintenance charge mode.
Both
WATERPROOF
DELTRAN BATTERY TENDER® International Battery
Chargers will automatically monitor and maintain the battery at full charge.

SPECIAL FEATURES:
The
WATERPROOF
DELTRAN BATTERY
TENDER® International Battery Chargers have the following special features:
SPARKPROOF:
The battery charger DC output leads, either ring
terminals or alligator clips must be connected to a battery before an output
voltage is developed by the battery charger.
SHORT CIRCUIT PROTECTION:
The
battery charger can sustain a
short circuit connection directly across its DC output terminals indefinitely
without any risk of either electric shock or excessive heat.
REVERSE POLARITY PROTECTION:
The
battery charger is
protected internally against any damage due to the DC output leads being
connected to the opposite polarity battery post. No damage will result to either
the battery or the battery charger.
TIME REQUIRED TO CHARGE A BATTERY:
The WATERPROOF
DELTRAN BATTERY TENDER® International Battery
Chargers charge at a rate of either 0.8 Amps (0.8 Amp-Hours per hour) or 1.25
Amps (1.25 Amp-Hours per hour). Therefore, a fully discharged 15 Amp-Hour
battery will take approximately 15 hours or 9.6 hours respectively, to recharge
to 80% capacity. Some large automotive or marine, deep cycle type batteries
may take several days to fully recharge.
WORKING WITH A DEAD BATTERY OR A BATTERY WITH A VERY
LOW VOLTAGE:
If you try to charge a dead battery having a voltage below 3 Volts, the
WATERPROOF
DELTRAN BATTERY TENDER® International Battery
Chargers will not start to charge because an internal safety circuit prevents the
battery chargers from generating any DC output voltage.
NOTE:
If a 12 Volt, Lead-Acid battery has an output voltage of less than 9 volts when
it is at rest, when it is neither being charged nor supplying electrical current to
an external load, there is a good chance that the battery is defective. As a
frame of reference, a fully charged 12-Volt, Lead-Acid battery will have a rest-
state, no-load voltage of approximately 12.9 volts. A fully discharged 12-Volt,
Lead-Acid battery will have a rest-state, no-load voltage of approximately 11.4
volts. That means that a voltage change of only 1.5 volts represents the full
range of charge 0% to 100% on a 12-Volt, Lead-Acid battery. Depending on
the manufacturer, and the age of the battery, the specific voltages will vary by
a few tenths of a volt, but the 1.5-volt range will still be a good indicator of the
battery charge %.
STATUS INDICATOR LIGHTS:
The following describes the
indicator light operation:
NEITHER THE AMBER OR GREEN LIGHT TURN ON (Both models)
–
This is an abnormal condition and most likely indicates that the charger is
not properly connected to the AC power.
AMBER LIGHT FLASHING
(1.25A only)
– The amber light flashing
indicates that the battery charger has AC power available and that the
microprocessor is functioning properly. If the amber light continues to
flash, then either the battery voltage is too low (less than 3 volts) or the
output alligator clips or accessory ring terminals are not connected
correctly.
