Maintain Mode
When the CHARGED LED is lit, the charger has started Maintain Mode.
In this mode, the charger keeps the battery fully charged by delivering a small
current when necessary. If the battery voltage drops below a preset level, the
charger will go back into Charge Mode until the battery voltage returns to the full
charge level, at which point the charger will return to Maintain Mode.
NOTE: The maintain mode technology utilized in Schumacher’s maintainers
allows you to safely charge and maintain a healthy battery for extended periods
of time. However, problems with the battery, electrical problems in the vehicle,
improper connections or other unanticipated conditions could cause excessive
voltage draws. As such, occasionally monitoring your battery and the charging
process is recommended.
NOTE: The charger automatically switches between Charge Mode and Maintain
Mode as necessary. The CHARGED LED may cycle on when the battery is at
full charge and off when the voltage drops below a preset level and the charger
goes into Charge Mode. This cycle will continue, and the CHARGED LED will
stay on for longer periods of time as the battery becomes more fully charged.
CALCULATING CHARGE TIME 13.
Use the following table to more accurately determine the time it will take to bring
a battery to full charge. First, identify where your battery fits into the chart.
Find your battery’s rating on the chart below, and note the charge time given. The
times given are for batteries with a 50% charge prior to recharging. Add more
time for severely discharged batteries.
