NOTE
If the battery pack is subjected to temperatures outside of the specified 5°C to 35°C (41°F to
95°F) range, charging will not commence. Under this circumstance, the battery indicator will
blink for 5 seconds. Charging will commence automatically once the temperature falls within
the allowable range. The battery temperature may rise as high as 60°C (140°F) during charging.
Recharging
The battery is automatically charged when the AC adapter is plugged into a socket.
Rapid charging commences when the POWER switch is turned off. Normal charging
takes place when the POWER switch is turned on.
Charging will terminate (Battery indicator changes from orange to green) automati-
cally when the battery is fully charged. In this state, it will remain fully charged as
long as the AC adapter is connected.
The AC adapter will become warm during charging or while in use; this is normal.
CAUTION
Always allow the battery to become completely discharged (low battery alarm sounds) before
recharging .
Since the battery is not pre-charged, be absolutely sure to charge these batteries before using
the computer for the first time. Charging commences automatically after the AC adapter is
connected.
A new battery or a battery that has not been used for a prolonged period of time will not be
fully charged after it has been charged/recharged only once.
It is recommended not to charge a battery that has not been completely discharged first (low
battery alarm sounds).
Do not charge a battery in any other computer or by using a recharger other than the one
specified.
When the duration of a battery’s operation has fallen by half or so, repeat the battery refresh
operation two or three times. If nothing happens even after this, the battery has reached the
end of its life span and should be replaced with a new one.
Installing and attempting to charge a battery pack that is already fully charged, or installing
and removing a battery pack several times in quick succession, can result in overcharging and
cause the battery to heat up. Such treatment can damage the battery pack.
