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.
