• The batteries 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 0°C to +20°C (+32°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 3-5 charge/discharge cycles.
• The batteries can be operated from -20°C to +50°C (-4°F to +122°F).
• Low operating temperatures reduce the capacity that can be drawn; very high
operating temperatures will reduce the service life of the battery.
