Charging / first-time use
• For all batteries
• The battery must be charged prior to using it for the first time because it is
delivered with an energy content as low as possible.
• 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-lon batteries
• For new batteries or batteries that have been stored for a long time (> three
months), it is effectual to make only one charge/discharge cycles.
• For Li-lon battteries, 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.
• For NiMH batteries
• For new batteries or batteries that have been stored for a long time (> three
months), it is effectual to make 3 - 5 charge/discharge cycles.
