and the Charge LEDs will illuminate (depending on the 

health of the battery) indicating the charging process 

has started.

6.) The charger can now be left connected to the battery 

at all times to provide maintenance charging.

Connecting to the Battery.

Do not connect the AC power plug until all other connections 

are made. Identify the correct polarity of the battery terminals 

on the battery. The positive battery terminal is typically 

marked by these letters or symbol (POS,P,+). The negative 

battery terminal is typically marked by these letters or symbol 

(NEG,N,-). Do not make any connections to the carburetor, 

fuel lines, or thin, sheet metal parts. The below instructions 

are for a negative ground system (most common). If your 

vehicle is a positive ground system (very uncommon), follow 

the below instructions in reverse order.

1.) Connect the positive (red) battery clamp or eyelet terminal 

connector to the positive (POS,P,+) battery terminal. 

2.) Connect the negative (black) battery clamp or eyelet 

terminal connector to the negative (NEG,N,-) battery terminal 

or vehicle chassis. 

3.) Connect the battery charger’s AC power plug into a 

suitable electrical outlet. Do not face the battery when making 

this connection.

4.) When disconnecting the battery charger, disconnect in the 

reverse sequence, removing the negative first (or positive first 

for positive ground systems).

Begin Charging.

1.) Verify the voltage and chemistry of the battery.

2.) Confirm that you have connected the battery clamps or 

eyelet terminal connectors properly and the AC power plug is 

plugged into an electrical outlet.

3.) The charger will begin in Standby mode, indicated by an 

orange LED. In Standby, the charger is not providing any 

power. 

4.) Press the mode button to toggle to the appropriate 

charge mode (press and hold for three seconds to enter an 

advanced charge mode) for the voltage and chemistry of 

your battery.

5.) The mode LED will illuminate the selected charge mode
