Primary use/charging
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.
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 
charger or on a Leica Geosystems product deviates significantly from the actual 
battery capacity available.
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.
Operation/Discharging
The batteries can be operated from -20°C to +55°C/-4°F to +131°F.
