7-4 Caring for the Computer
Battery Pack Guidelines
Optimal Use of the ML910 RUGGED NOTEBOOK Battery
The battery is a consumable product and its performance will gradually degrade based
on usage. To minimize battery degradation and ensure longer life, limit the number of
charges and ensure the battery is not exposed to ambient temperatures greater than
50ºC (122ºF). If possible, the battery pack should only be recharged when it is nearly
fully discharged. It is recommended to store the battery removed from the
ML910
RUGGED NOTEBOOK with a nominal charge to prevent the battery from completely
discharging. A full charge is recommended if the battery is to be stored in the ML910
RUGGED NOTEBOOK .
For optimal use, users should avoid the following:
• Using battery power for short periods of time and then charging the battery
repeatedly.
• Using or storing battery in a high temperature location.
Charging
Charge and discharge time will differ depending on the computer’s power status and
temperature. Battery charging time increases when the computer’s power is on and
this is also dependent on the battery’s temperature. To charge the battery more
quickly, power off the computer or place it on standby or in the hibernation mode.
Battery charging time also increases when in low
(below 10ºC, or 50ºF) or high (above
30ºC or 86ºF) temperature environments. During normal charging, (between 32ºF and
113ºF) the battery indicator will glow amber. When full, the indicator will glow green.
The
ML910 RUGGED NOTEBOOK battery will not be charged if its temperature is
outside the allowed range of 0º to 45ºC (32ºF to 113ºF). During this condition, the
battery indicator will not be illuminated.
•
The battery should be charged within a temperature range of 10°C to 35°C
(50°F to 95°F).
When the temperature outdoors is high (35ºC or above), the temperature inside the
battery will be higher. Avoid charging the battery where the temperature is high, such
as inside a vehicle, with all its windows closed and/or exposed to the hot sun or other
places where the ambient temperature is high. Although the battery can also be
charged in a temperature of 0ºC, the charging time will take longer and the battery
capacity will be greatly reduced.
•
It is not recommended to charge the battery more than once per day.
Constant recharging of the battery after every use accelerates battery degradation. To
increase battery life, it is recommended to recharge the battery no more than once per
day or when the remaining charge drops below 20%. To increase battery life, the
computer will not charge the battery immediately after it has been fully charged unless
the remaining charge has fallen to less than 95%.
