4.5.1Operating 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 form 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.
