– when frequently charging the battery pack
– when using, charging, or storing in high temperature condition
 To avoid hastening the deterioration of the battery pack thereby prolonging its
useful life, minimize the number of times you charge it so as not to frequently
increase its internal temperature.
 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.
