Batteries
The CS25 tablet computer is designed to work with two removable battery packs
placed inside the battery pack compartment. The fully charged battery packs provide
several hours of battery life, which can further be extended by using power manage-
ment features through the BIOS setup. The system includes power management
software which allows the battery to report the amount of charge percentage left in
the battery. Refer to "4.2 Hot Tab Software Utility Functions".
Operating Principles
•
The battery must be charged prior to using it for the first time because it is deliv-
ered with an energy content as low as possible.
•
The permissible temperature range for charging is between 0°C to +40°C/ +32°F
to +104°F. For optimal charging, we recommend charging the batteries at a low
ambient temperature of +10°C to +20°C/+50°F to +68°F if possible.
•
It is normal for the battery to become warm during charging. Using the chargers
recommended by Leica Geosystems, it is not possible to charge the battery if the
temperature is too high.
