Important: During Manual Mode, the GR1-120 charges
the battery based on the voltage, current, and charge
duration that you select. Because the charger does not
monitor the charging progress to optimize charging levels
or reduce charging, you should monitor the battery’s state
of charge and temperature. Any charging after the battery
is fully charged will result in excessive battery
temperature and gassing, which can shorten battery life.
TIMED CHARGING
If you have selected a charging time (between 5 and 120
minutes), the charger will analyze the battery, briefly
display the measured voltage and available starting
current in CCA, and begin charging at the selected levels.
During charging the charger keeps you informed by
displaying the charging voltage, charging current,
remaining time to charge, charging mode, and the
amount of charge put back into the battery in amp-hours.
TIMED CHARGE COMPLETION
The manual charge session is complete when the
selected time to charge goes to zero.
The charger will alert you with an alarm and display the
ending charge voltage, total charging time, charging
mode, and the final amount of charge put back into the
battery in amp-hours.
The alarm will sound every 30 seconds until you press
the STOP button or disconnect the charger clamps from
the battery.
