Nokia 5165 User Manual page 79

When the phone is charging, no lights are displayed on the
stand; check the charging status of the phone battery on
the phone display.
Charging moves to the rear slot once the front battery is
100% charged.
When the spare battery is charging, check the status indicator
on the left side of the charging stand. A red light indicates
that the battery is charging; a green light indicates that the
battery is charged to at least 80% of its capacity.
