1. Operation
The BC-1WD/1WDCE begins discharging once the POWER switch is
turned ON. It continues to give a booster charge until the voltage drop
of —AV (see the figures below), which occurs near the end of charging,
is detected. Trickle charging (charging at a slow rate to normally
maintain the battery in a fully charged condition and to protect against
self discharge) will be done after all of the inserted batteries have been
charged. Trickle charging automatically stops after 24 hours of
continuation. Further, the charging status varies, as seen in the
diagrams below, according to whether you are in the auto refresh
mode or the refresh cancellation mode.
