Charging / first-time use
•
For all batteries
• The battery must be charged prior to first use because it is delivered with as
low an energy content 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. When using the
chargers recommended by Leica Geosystems, it is not possible to charge the
battery if the temperature is too high.
• For Li-lon batteries
• For new batteries or batteries that have been stored for a long time (> three
months), it is effective to complete only one charge/discharge cycle otherwise
they can become damaged.
• For Li-lon 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.
