7.2 Batteries
7.2.1 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 and +40°C/+32°F
and +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 recom-
mend 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.
Operation /
Discharging
• The batteries can be operated from -20°C to +65°C/-4°F to +149°F.
• Low operating temperatures reduce the capacity that can be drawn; high operating
temperatures reduce the service life of the battery.
