Charge the battery pack between 10 °C ~ 30 °C (50 °F ~ 86 °F) temperature
range. A higher environment temperature will cause the battery pack’s
temperature to rise. Avoid charging the battery pack inside a closed
vehicle and in hot weather condition. Also, charging will not start if the
battery pack is not within the allowed temperature range.
It is recommended that you do not charge the battery pack more than
once a day.
It is recommended that you charge the battery pack with the computer’s
power off.
To maintain the battery pack’s operating efficiency, store it in a cool
dark place removed from the computer and with 30 % ~ 40 % charge
remaining.
Important guidelines when using the battery pack.
When installing or removing the battery pack take note of the
following:
– avoid installing or removing the battery pack when the computer is in
Sleep mode. Abruptly removing the battery pack may cause loss of
data or the computer may become unstable.
– avoid touching the battery pack terminals or damage may occur,
thereby causing improper operation to it or the computer.
The computer’s input voltage and surrounding temperature will directly
affect the battery pack’s charge and discharge time:
– charging time will be prolonged when the computer is turned on.
To shorten the charging time, it is recommended that you place the
computer in sleep or hibernation mode.
– a low temperature will prolong the charging time as well as hasten
the discharge time.
When using battery power in an extremely low temperature environment,
you may experience shortened operating time and incorrect battery level
reading. This phenomenon comes from the chemical characteristics of
batteries. The appropriate operating temperature for the battery is -10
°C ~ 50 °C (14 °F ~ 122 °F).
Do not leave the battery pack in storage for more than six months
without recharging it.
