Operating Principles

• 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.
• 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.
