Battery power
system
The CS25 plus 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 soft-
ware which allows the battery to report the amount of charge percentage left in the
battery. Refer to "5.2 Hot Tab Software Utility Functions".

Operating Principles
First-time use /
Charging batteries
• The battery must be charged prior to using it for the first time.
• 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.
• For Li-Ion batteries, a single refreshing cycle is sufficient. We recommend carrying
out a refreshing cycle when the battery capacity indicated on the charger or on a
Leica Geosystems product deviates significantly from the actual battery capacity
available.
Operation /
Discharging
• The batteries can be operated from -20°C to +55°C/-4°F to +131°F.
• Low operating temperatures reduce the capacity that can be drawn; high operating
temperatures reduce the service life of the battery.
