Calculating Charge Time; Maintain Mode - Schumacher SpeedCharge XM1-5 Owner's Manual

Maintain Mode

When the CHARGED
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
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
stay on for longer periods of time as the battery becomes more fully charged.
