High Temperatures
Additionally, the amount of energy available above 68
d
F
(20
d
C) does not increase all that much. Exposure to
temperatures above 104
d
F (40
d
C) cause the chemicals
inside the battery to slowly degrade, thus slowly aging the
battery. Therefore, for best battery life, avoid using or
storing your mobile computer in high temperature
environments.
Guidelines for Hours of Operation
The hours of operation (8--10) shown on the specification
page are for a mobile computer in an environment of 72
d
F
(22.2
d
C), using backlight about 10% of the time, no
scanning, and no radio installed.
Low Battery Shutdown
If your computer shuts down because of low battery
condition, your computer will not operate. The computer
does this to ensure that the data is protected. Although the
battery will protect the data against loss for several hours,
it is best to connect your mobile computer to a power source
when you first detect a low battery condition.
Your computer contains an internal super capacitor (a
temporary power storage device) that protects data for up to
3 minutes to allow for replacing the main battery pack.
"
NOTE:
Your computer must be put into suspend mode before changing the
main battery to ensure no loss of data.
The battery power fail level is set so that after the system
shuts down in a low battery condition, there is still
sufficient charge to allow the unit to remain configured,
keep proper time and maintain DRAM memory for a
minimum of 30 minutes at room temperature
if
the main
battery remains in the mobile computer.
