DISPLAY MODE SWITCH
Use this switch button to set the function of
the digital display to one of the following.
• BATTERY %: The digital display shows
an estimate of the percent of charge of
the battery connected to the charger
battery clamps.
• VOLTAGE: The digital display shows the
voltage at the charger battery clamps in
DC volts.
• ALTERNATOR %: The digital display
shows an estimated percentage of the

specialized vehicles. The 6V REGULAR
battery type is not selectable for batteries
greater than 8.5V DC.
The voltage displayed during charging is
the charging voltage and usually will be
higher than the battery's resting voltage.
