NOTE: If the engine does turn over but 

never starts, there is not a problem with 

the starting system; there is a problem 

somewhere else with the vehicle. STOP 

cranking the engine until the other problem 

has been diagnosed and corrected.

When an Automatic Charge is performed, 

the charger switches to the maintain mode 

automatically after the battery is charged. 

If charging cannot be completed normally, 

charging will abort. When charging aborts, 

the charger’s output is shut off and the 

BOOST/CHARGING (yellow/orange) LED 

will flash. Do not continue attempting to 

charge this battery. Have it checked or 

replaced.

Desulfation could take 8 to 10 hours. If 

desulfation fails, charging will abort and 

the BOOST/CHARGING (yellow/orange) 

LED will flash.

Charge completion is indicated by the 

CHARGED/MAINTAINING (green) LED. 

When pulsing, the charger has switched to 

the maintain mode of operation. 

When the CHARGED/MAINTAINING  

(green) LED is pulsing, the charger has 

started maintain mode. In this mode, the 

charger keeps the battery fully charged 

by delivering a small current when 

necessary. If the charger has to provide 

its maximum maintain current for a 

continuous 12 hour period, it will go into 

abort mode (see Aborted Charge section). 

This is usually caused by a drain on the 

battery or the battery could be bad. Make 

sure there are no loads on the battery. If 

there are, remove them. If there are none, 

have the battery checked or replaced. 

The 28.71331 charges and maintains 12 

volt batteries, keeping them at full charge. 

NOTE: The maintain mode technology 

allows you to safely charge and maintain 

a healthy battery for extended periods 

of time. However, problems with the 

battery, electrical problems in the 

vehicle, improper connections or other 

unanticipated conditions could cause 

excessive current draws. As such, 

occasionally monitoring your battery and 

the charging process is required.

Times are based on a 50% discharged battery and may change, depending on age  

and condition of battery.

A minimal amount of care can keep your 

battery charger working properly for years.

• Clean the clamps each time you are 

finished charging. Wipe off any battery 

fluid that may have come in contact with 

the clamps to prevent corrosion.

• Occasionally cleaning the case of the 

charger with a soft cloth will keep the 

finish shiny and help prevent corrosion.

• Coil the input and output cords neatly 

when storing the charger. This will help 

prevent accidental damage to the cords 

and charger.

• Store the charger unplugged from the AC 

power outlet in an upright position.  

• Store inside, in a cool, dry place. Do not 

store the clamps on the handle, clipped 

together, on or around metal, or clipped 

to the cables.
