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, BATTERY
TENDER
® chargers will not start. An internal safety circuit prevents the
BATTERY TENDER ® chargers from generating any output voltage unless it
senses at least 3 Volts at the charger output. In this situation, the amber light will
continue to flash (International Plus and EURO400), indicating that a charge has
not been initiated (WP800 does not show any light at all).
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 INDICATING LIGHTS: If neither light is lit, then the battery is not
properly connected and/or the charger is not plugged into AC power. The
following describes light operation:
 AMBER LIGHT FLASHING – The amber light flashing indicates that the
battery charger (International Plus and EURO400) 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 ring terminals are not connected correctly.

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.
 GREEN LIGHT FLASHING – (International Plus and EURO400 only) When
EURO400 shows a green light flashing, the battery is 80% charged and may
be used if necessary. When the green light is flashing, and the amber light is
on (International Plus), 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.

GREEN LIGHT ON STEADY – All chargers: When the green light stops
flashing and burns steady, the charge is complete and the battery can be
returned to service if necessary. It can also stay connected to maintain the
battery for an indefinite period of time
STATUS INDICATING SYMBOLS: The following symbols are located next to the
status indicator lights.
The symbol next to the AMBER light represents a partially charged
battery. The solid band across the bottom is green in color. The
background is yellow. The green area indicates the charged portion of
the battery and the yellow area represents the uncharged portion.
The symbol next to the GREEN light represents a fully charged
battery. The entire area inside the battery outline is green.

TROUBLESHOOTING CHECK LIST:
1.
CHARGER LIGHTS DO NOT TURN ON:
a. Remove the charger from the AC outlet and recheck
that the battery charger clamps are connected to the
correct terminals and are making a clean tight
connection.
b. Check to make sure AC outlet is supplying power by
plugging in a lamp, an appliance, or a voltage meter.
2. THE GREEN LIGHT GOES ON IMMEDIATELY WHEN
CHARGING A DISCHARGED BATTERY:
a.
The battery may be defective, take battery to the dealer
to be tested.
3. CHARGER IS CHARGING BUT THE GREEN LIGHT DOES
NOT GO ON:
a.
The battery may be defective, take battery to the dealer
to be tested.
b. The battery has an excessive current draw, remove
battery from equipment.
4. THE AMBER LIGHT COMES ON WHEN STORAGE
CHARGING BATTERIES:
a.
The battery may be defective, take battery to the dealer
to be tested.
b. The battery has an excessive current draw, remove
battery from equipment.
