USER INSTRUCTIONS
AUTOMATIC CHARGING AND BATTERY STATUS MONITORING:
Battery Tender® 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. The charger output power, voltage, and current depends
on the condition of the battery it is charging. Battery Tender
®
chargers have
several status LED indicators that provide a visual means to determine the
operating mode of the charger and hence the condition of the battery
connected to the charger.
When AC power is first applied to the charger all of the LEDs will illuminate
for two to three seconds before starting the charge sequence listed below.
The two battery level status LED indicator lights (Amber LED 1, Green LED
3) are available to determine whether the charger is operating in one of the
four primary charge modes:
1) Qualification/Initialization mode: The Monitor Circuit verifies
appropriate battery voltage levels and good electrical continuity
between the battery and the charger DC output.
2) Bulk mode (full charge, constant current, battery is 0% to 80%
charged)
3) Absorption mode (high constant voltage, battery is 80% to 100%
charged).
4) Storage/float maintenance mode (low constant voltage, battery is
100% to 103% charged).
When the battery is fully charged, the battery level status Green LED (3)
indicator will turn solid green and the charger will switch to a storage/float
maintenance charge mode. The Battery Tender
®
charger will automatically
monitor and maintain the battery at full charge.

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.
ATTENTION: The Battery Tender
®
CHARGER HAS A SPARK FREE
CIRCUITRY. The output alligator clips or ring terminals will not spark when
they are touched together. The Battery Tender
®
charger will not produce an
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.
NOTE:
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 3.0 amps or 3 amp-hours per
hour. Therefore, a fully discharged 15 amp-hour battery will take
approximately 4 hours to recharge to 80% capacity.
