Maintain Mode
When the CHARGED (green) 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 charger automatically switches between Charge Mode and Maintain
Mode as necessary. The CHARGED (green) 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
(green) LED will stay on for longer periods of time as the battery becomes
more fully charged.
