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
Battery Tender
®
800 charger will not start. An internal safety circuit
prevents the charger 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, indicating that a charge has not been initiated.
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 LIGHT: If the light is not 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 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. The fuse in the output alligator clips or ring
terminals may also be blown.
<
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
–When the green light is flashing, 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
–When the green light 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

TROUBLESHOOTING CHECK LIST:
1.
CHARGER LIGHTS DO NOT TURN ON:
a.
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.
