Battery Pack Guidelines
 Recharge the battery pack when it is nearly discharged. When
recharging, make sure that the battery pack is fully charged. Doing so
may avoid harm to the battery pack.
 The battery pack is a consumable product and the following conditions
will shorten its life:
– when frequently charging the battery pack
– when using, charging, or storing the battery 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.
