4.2 Working with the Battery
Charging / first-time use
• 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.
• 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.
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; very high oper-
ating temperatures reduce the service life of the battery.
• For Li-Ion batteries, we recommend carrying out a single discharging and charging
cycle when the battery capacity indicated on the charger or on a Leica Geosystems
product deviates significantly from the actual battery capacity available.
Change the battery
step-by-step
The polarity of the battery is displayed inside the battery housing.
Open the battery compartment (1) and
remove the battery holder (2).
Remove the battery from the battery
holder (3).
Insert the new battery into the battery
holder (4), ensuring that the contacts are
facing outward. The battery should click
into position.
Insert the battery holder back into the
battery compartment (5) and turn the
knob to lock the battery holder in place
(6).
