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 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. Deltran Battery Tender® International Battery
Chargers have 2 status lights (one amber, and one green) for each charger
output 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.
Deltran
Battery Tender® International Battery Chargers will automatically monitor and
maintain the battery at full charge.
SPECIAL FEATURES: Deltran Battery Tender® International Battery
Chargers & Battery Management Systems 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.
6
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 Deltran Battery Tender® International Battery Chargers charge at a rate of
1.25 Amps (1.25 Amp-Hours per hour). Therefore, a fully discharged 15 Amp-
Hour battery will take approximately 10 hours 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 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 (LEDs): The following describes
the indicator light operation:
¾ NEITHER THE AMBER OR GREEN LIGHT TURN ON – This is an
abnormal condition and most likely indicates that the charger is not
properly connected to the AC power.
¾ AMBER LIGHT FLASHING – 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.
¾ AMBER LIGHT ON STEADY – Whenever the amber light is on steady, a
battery is connected properly and the charger is charging the battery. The
amber light will remain on until the charger completes the charging stage.
¾ GREEN LIGHT FLASHING – When the green light is flashing, and the
amber light is on, the battery is greater than 80% charged and may be
removed from the charger and used if necessary. Whenever possible,
leave the battery on charge until the green light is solid.
¾ GREEN LIGHT ON STEADY – When the green light stops flashing and
