Meaning
One of the following
conditions exists.
• An incompatible
battery pack has
been connected.
• Before the start of
charging, the
output voltage of
the charger was
different from the
specified voltage.
• After the start of
charging, the
battery voltage did
not rise to the
charging voltage
within a specified
period.
• After the start of
charging, the
battery connector
voltage has
exceeded the
specified voltage.
• After the start of
charging, the
battery connector
voltage has
dropped below the
initial value.
• A charging current
other than that
corresponding to
the connected
battery pack was
detected during
charging.
If any of the above
conditions occur, try
recharging the
battery pack two or
three more times. If
the condition
persists, the battery
pack is probably
defective and should
be replaced.
