Batteries

Operating Principles
)
Primary use/charging
•
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.
•
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 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 operating temperatures reduce the service life of the battery.
