Charging / first-time use
• For new batteries or batteries that have been stored for a long time (> three months), we recommend performing 3 to 5 charge/discharge cycles
• The battery must be charged before using it the first time, because it is delivered with an energy content as low as possible or might be in sleep mode.
• The permissible temperature range for charging is from 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 once the temperature is too high
Operation/discharging
• 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; high operating temperatures reduce the service life of the battery
Charging the battery
1. Connect the battery to the battery charger and the battery charger to a mains socket.
2. While charging, the green LED flashes, increasing from one to four LED until fully charged.
☞ Eight hour (acquisition), with two batteries. Extended, by the hot swap capability.
