Before attempting to install, use or charge the battery pack, it is critical that you
review and follow the important safety guidelines, described in the following chap-
ters.

Operating Principles
Charging / first-
time use
•
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.
•
For new batteries or batteries that have been stored for a long time (> three
months), it is effectual to make only one charge/discharge cycle.
•
For Li-Ion batteries, a single discharging and charging cycle is sufficient. We
recommend carrying out the process when the battery capacity indicated on the
