 (red) LED lit: Indicates the battery is not properly 

connected to the charger.

 (red) LED blinking: Indicates the charger is in abort 

mode.
CHARGING 

 (yellow) LED lit: Indicates the charger is charging the  

battery.

 (green) LED lit: Indicates the battery is fully charged and the 

charger is in maintain mode

NOTE: See the Operating Instructions section for a complete description of the 

charger modes.

Ensure that all of the charger components are in place and in good 

working condition, including the plastic boots on the battery clips.
Connect the battery following the connection instructions described in 

Using the Quick-Disconnect Cable Connectors section.
Set the Amp/Volt Selector Switch to the proper setting for the battery 

being charged.
Connect the AC power following the precautions listed in Section 8.

If you’ve connected everything correctly, the CHARGING 

 (yellow)

LED should be lit indicating that the charger is charging. If the CHARG-
ING 

 (yellow) LED does not light or if the CHECK BATTERY 

(red) LED is lit, check the connections or have the battery checked/

replaced.

NOTE: This charger is equipped with an auto-start feature. It will not supply 

current to the battery clips until a battery is properly connected. Unlike tradi-

tional chargers, the clips will not spark if touched together.
USING THE QUICK-DISCONNECT CABLE CONNECTORS 

Connect any of the three output cable assemblies to the charger in seconds. 

Make sure to place the charger on a dry, non-flammable surface like metal or

concrete.
NOTE: Never connect the clamp and ring terminal connectors together for use 

in other applications, such as external battery or other power source charging, 

or to extend the output cable length, as reverse polarity and/or overcharge 

conditions will occur.
50 amp Battery Clips 

Connect the end of the 50 amp battery clips cable Quick-Connect to the 

charger.
Follow the steps in sections 6 and 7 to connect the output clips to the 

battery. 
After a good electrical connection is made to the battery, plug the power 

cord into a 3-prong grounded 120V AC electrical wall outlet. Make

sure to place the charger on a dry, non-flammable surface like metal or

concrete. 

Permanent Ring Connectors  

The ring connectors permanently attach to the battery providing easy access 

to quickly charge your battery. This application is appropriate for motorcycles, 

lawn tractors, ATVs and snowmobiles. 

To permanently attach to a battery, loosen and remove each nut from 

the bolt at the battery terminal. 
Connect the red POSITIVE ring connector ring to the POSITIVE battery 

terminal. 
Connect the black NEGATIVE connector ring to the NEGATIVE battery 

terminal. 
Replace and tighten the nuts to secure. 

Connect the end of the ring terminal cable Quick-Connect to the char-

ger. Take care to keep the wires and plug away from metal and moving 

parts. 
Plug the charger power cord into a 3-prong grounded 120V AC electrical

wall outlet. Make sure to place the charger on a dry, non-flammable

surface like metal or concrete. 

12V ACCESSORY PLUG 

Charge or maintain your battery without lifting the hood.  

Connect the end of the 12V Accessory Plug Cable Quick-Connect to the 

charger.
Insert the 12V accessory plug into the 12V accessory outlet.

Route the power cord from charger through the vehicle’s open window.

Plug the charger power cord into a 3-prong grounded 120V AC electrical

wall outlet. Make sure to place the charger on a dry, non-flammable

surface like metal or concrete. 

If the charger does not detect a properly connected battery, the CHECK BAT-
TERY 

 (red) LED will light continuously until such a battery is detected.

Charging will not begin while the CHECK BATTERY 

 (red) LED is on..

Completion of Charge 
Charge completion is indicated by the CHARGED 

 (green) LED. When

lit, the charger has stopped charging and switched to the Maintain Mode of

operation. 
Maintain Mode (Float-Mode Monitoring) 
When the CHARGED 

 (green) LED is lit, 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 battery voltage drops below a preset level, 

the charger will go back into Charge Mode until the battery voltage returns to

the full charge level, at which point the charger will return to Maintain Mode.

The voltage is maintained at a level determined by the 6 volt or 12 volt battery 

type selected.
NOTE: The charger automatically switches between Charge Mode and
Maintain Mode as necessary. The CHARGED

 (green) LED will cycle on

when the battery is at full charge and off when the voltage drops below a preset 

level and the charger goes into Charge Mode. This cycle will continue, and the
CHARGED 

 (green) LED will stay on for longer periods of time as the bat-

tery becomes more fully charged.
Desulfation Mode 

If the battery is left discharged for an extended period of time, it could become 

sulfated and not accept a normal charge. If the charger detects a sulfated 

battery, the charger will switch to a special mode of operation designed for 

such batteries. If successful, normal charging will resume after the battery is 

desulfated. Desulfation could take up to 8 hours. If desulfation fails, charging
will abort and the CHECK BATTERY 

 (red) LED will blink.

If charging can not be completed normally, charging will abort. When charging 
aborts, the charger’s output is shut off, and the CHECK BATTERY 

 (red)

LED will blink. To reset after an aborted charge, either disconnect the battery or 

unplug the charger.

This charger adjusts the charging time in order to charge the battery com-

pletely, efficiently and safely.
This battery charger has a rated output of 2 and 4 amperes. This output will

vary with the age and condition of the battery being charged. If the battery has 

only been slightly discharged, it can be charged in less than a few hours. The 

same battery will take longer to charge if it is very weak.

Before performing maintenance, unplug and disconnect the battery charger 

(see Sections 6, 7 and 8).
After use, unplug the charger and use a dry cloth to wipe all battery corro-

sion and other dirt or oil from the terminals, cords, and the charger case.
Ensure that all of the charger components are in place, securely attached 

and in good working condition, including the plastic boots on the battery 

clips.
Servicing does not require opening the unit, as there are no user-service-

able parts.
