BATTERY VOLTAGE SELECT BUTTON
®
The Battery Tender charger has a "SELECT" button which allows you to
switch between charging a 6-volt battery or a 12-volt battery.
The battery voltage can be selected once the charger has AC power
applied and before the charger is connected to the battery.
Once the charger has AC power and is also connected to the battery the
voltage (12V or 6V) selection cannot be changed. To change the mode,
disconnect the battery from the charger.
If the AC power is interrupted the charger will resume charging at the last
battery voltage setting used.
The charger can also detect if the incorrect battery voltage has been
selected once the connection has been made to the battery. One of the
Green LEDs (LED 1 or 2) located next the 12V or 6V symbol will flash
preventing the charge cycle from starting. In order to begin a new charge
cycle, reset the charger by disconnecting it from the AC supply as well as
the wrong or defective battery for 7-10 seconds. Reconnect the AC supply
and the charger will be ready for a new charge cycle.

they are touched together. The Battery Tender
output voltage until it senses at least 3 volts from the battery. It must be
connected to a battery with the correct polarity before it will start charging a
battery. Therefore, if you plug the AC power cord into an AC power outlet,
and if the output alligator clips or ring terminals are not connected to a
battery, and if you touch the alligator clips or ring terminals together, there
will be no electrical spark.
THE OUTPUT CLIPS OR RING TERMINALS MUST BE CONNECTED TO
A BATTERY BEFORE THE CHARGER CAN PRODUCE AN OUTPUT
VOLTAGE.
TIME REQUIRED TO CHARGE A BATTERY:
®
The Battery Tender charges at a rate of 1.25 Amps or 1¼ Amp-hours per
hour. Therefore, a fully discharged 15 Amp-Hour battery will take
approximately 9½ hours to recharge to 80% capacity.

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 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 LED will continue to flash,
indicating that a charge has not been initiated.
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 (Amber LED 1) – The amber LED
flashing indicates that the battery charger has AC power available
and that the microprocessor is functioning properly. If the amber
LED 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 (Amber LED 1) – Whenever the
amber LED is on steady, a battery is connected properly and the
charger is charging the battery. The amber LED will remain on until
the charger completes the charging stage.

GREEN LIGHT FLASHING (Green LED 3) – When the green LED
is flashing and the amber LED (Amber LED 1) is solid 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 (Green LED 3) – When the green
LED 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
