Essential Battery Operating Principles
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. Low oper-
ating temperatures reduce the capacity that can be drawn; very high operating
temperatures reduce the service life of the battery.
