Battery TenderPlus: Models: 12V1.25A and 6V1.25A
The Battery Tender®Plus
12 Volt, 1.25 Amp
6 Volt, 1.25 Amp
GENERAL DESCRIPTION:
The Battery TenderPlus battery
charger is a desktop, portable, linear
power converter that has a true DC
output at a maximum power level of approximately 18 or 9 watts respectively for the 12V
and 6V models. Both models have a maximum output charging current of 1.25 amps.
NOTE: In recent years, the Sealed, GRT (Gas Recombinant Technology), AGM
(Absorbed Glass Matte), Lead-Acid battery has enjoyed widespread acceptance in a
variety of applications traditionally dominated by flooded battery technology. The
Battery TenderPlus battery charger circuitry provides a superior configuration to
accommodate the more demanding recharge requirements of this superior battery
technology. Although the original Battery Tenderbattery charger will recharge AGM
batteries, the full recharge time is longer than with the Battery TenderPlus battery
charger. This is because of the different implementation of the absorption charge mode
between these two chargers. Those differences are spelled out in detail in other
documents on the website. See Utility / Frequently Asked Questions.
OUTPUT CABLE CONNECTIONS: The battery charger DC output cable has
a molded, quick disconnect plug. The ring terminal, alligator clip, and cigarette adapter
output cable accessories all contain the mating plug.
STATUS INDICATOR LIGHTS: The following describes the operation of the
status indicator lights:
 RED FLASHING - When the red light is flashing, the AC power is applied to the
charger & the microprocessor circuitry is functioning properly, but the DC output
cables are not connected correctly.
 RED - When the red light is on, the battery charger is in the process of fully charging
the battery. In order to properly charge large capacity batteries, the charger may
remain in this mode for several hours or even days.
 GREEN FLASHING - When the green light is flashing, and the red light is on, the
battery is greater than 80% charged and may be removed from the charger and used if
necessary. Leave the battery on charge until the green light is solid whenever
possible. Once the green light begins to flash, it will remain flashing until either the
battery charger output current drops below 0.1 amp, or until 6 to 8 hours has elapsed.

 GREEN - When the green light is lit, the battery charger is in the storage mode of
charge. In this mode the charger will maintain the battery at full charge.
SPECIAL TROUBLESHOOTING INFORMATION:
1) NEITHER OF THE CHARGER STATUS INDICATOR LIGHTS TURN ON:
a) Disconnect the charger AC power plug from the AC outlet and recheck that the
battery charger alligator clips or ring terminals are connected to the correct
polarity battery terminals and that they are making a clean, tight connection.
b) Check to make sure that the AC outlet is supplying power by plugging in
another appliance like a lamp, or check the outlet voltage with a voltmeter.
2) THE STORAGE/FLOAT MAINTENANCE STATUS INDICATOR LIGHT
(GREEN LIGHT) GOES ON IMMEDIATELY WHEN CHARGING A
BATTERY KNOWN TO BE DISCHARGED:
a) The battery may be defective. Take the battery to the dealer to be tested.
b) The electrical connections between the charger and the battery may not be
completely secured.
3) AFTER THE STORAGE/FLOAT MAINTENANCE STATUS INDICATOR
LIGHT (GREEN LIGHT) HAS BEEN ON, AND THE AC POWER IS
REMOVED FROM THE CHARGER AND THEN IMMEDIATELY
RECONNECTED, IT SEEMS TO TAKE TOO MUCH TIME FOR THE
GREEN LIGHT TO COME ON AGAIN.
a) This is NORMAL OPERATION for the Battery TenderPlus.
b) Whenever AC power is removed from the charger, including momentary AC
power outages, the charge cycle resets. Therefore, the battery charge current
either has to drop to below 0.1 amp or 6 to 8 must elapse before the green light
stops flashing.
4) AFTER THE STORAGE/FLOAT MAINTENANCE STATUS INDICATOR
LIGHT (GREEN LIGHT) HAS BEEN ON, THE RED LIGHT COMES ON.
a) This is NORMAL OPERATION for the Battery TenderPlus.
b) There has been a momentary AC power outage that reset the charge cycle.
c) There is some other load or appliance drawing power from the battery. When
the battery voltage drops below 12.0V to 12.5V, the charge cycle resets.
