Digital Display
The Digital Display gives a digital indication of voltage of the battery, % of charge of the
battery or % of charging output of the alternator, depending on the Display Mode chosen.
Display Mode Button
Use this button to set the function of the digital display to one of the following:
Battery % The digital display shows an estimated charge percentage of the battery
connected to the charger battery clips. The percent indicated is an estimate based on
the present battery voltage. Connecting and reconnecting a battery during charging
or after charging is complete will cause the charger to recalculate the percentage and
may display a different percentage than was previously indicated.
Voltage The digital display shows the voltage at the charger battery clips in DC
volts. Keep in mind that this reading is only a battery voltage reading, and a false
surface charge may mislead you. We suggest that you turn on the headlights for a
couple of minutes before you read the meter. Read it a couple of minutes after you
have shut the headlights off. If the reading is less than 10.5 volts (5.2 volts for 6V
battery), the battery may be bad or the connection at the charger may be poor. If the
reading is 10.5 volts to 12.8 volts (5.2 volts to 6.4 volts for 6V battery), the battery
is low – recharge it. If the reading is above 12.8 volts (6.4 volts for 6V battery) the
battery is charged. NOTE: The voltage display is not available during charging, and
the digital display will default to BATTERY %.
Alternator % The digital display shows an estimated output percentage of the
vehicle’s charging system connected to the charger battery clips as compared to a
properly functioning system. The alternator percent range is from 0 to 100%. Readings
below 0 (13.2 volts) will read LO and readings above 100% (14.6 volts) will read
HI. If you get a HI or LO reading, have the electrical system checked by a qualied
technician. The percent indicated is an estimate based on the present alternator output.
