8

1.  Note the polarity of the battery posts 

by checking the identification marks 

on the battery: POSITIVE (POS, P 

or +) and NEGATIVE (NEG, N or -). 

The positive post is usually larger 

than the negative post.

2.  Attach at least a 24-inch-long, 

6-gauge (AWG), insulated battery 

cable to NEGATIVE (NEG, N or 

-) battery post. Rock and twist the 

clamp back and forth to be sure a 

solid electrical connection is made.

3.  Connect the red (POSITIVE) output 

clamp to the POSITIVE battery post. 

Rock and twist the clamp back and 

forth to be sure a solid electrical con-

nection is made.

4.  Position yourself as far away from 

the battery as possible, and then 

connect the black (NEGATIVE) 

output clamp to the free end of the 

cable.

5.  Plug the power cord into an AC 120V 

electrical wall outlet. The charger will 

be set to the Tester Mode for REGU-

LAR battery type.

6.  Press the appropriate control buttons 

to select the desired charge rate 

and battery type. The CHARGING 

(yellow) LED should light and the 

charging process should start. If the 

CHECK (red) LED is on, check for 

correct cable connections.

7.  To disconnect the charger, unplug 

its power cord before attempting 

to disconnect the charger clamps. 

Then, standing away from the bat-

tery, remove the output clamp from 

the NEGATIVE battery post. Finally, 

remove the output clamp from the 

POSITIVE battery post.

8.  Clean and store the charger in a dry 

location.

IMPORTANT: Follow all safety instruc-

tions and precautions when charging 

your battery. Wear complete eye protec-

tion and clothing protection. Charge your 

battery in a well-ventilated area.

A minimal amount of care can keep your battery charger working properly for years.

1.  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.

2.  Coil the input and output cords neatly when storing the charger. This will help pre-

vent accidental damage to the cords and charger.

3.  Occasional cleaning of the case of the charger with a soft cloth will keep the finish 

shiny and help prevent corrosion.

4.  Store the battery charger in a clean and dry location.
