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.
