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 Tablet PC’s power
off.
To maintain the battery pack’s operating efficiency, store it in a cool dark place
removed from the Tablet PC 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 Tablet PC is in
Sleep mode. Abruptly removing the battery pack may cause loss of
data or the Tablet PC may become unstable.
– avoid touching the battery pack terminals or damage may occur,
thereby causing improper operation to it or the Tablet PC.
The Tablet PC’s input voltage and surrounding temperature will directly affect
the battery pack’s charge and discharge time:
– charging time will be prolonged when the Tablet PC is turned on.
To shorten the charging time, it is recommended that you place the
Tablet PC 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.
