4.2 Batteries
4.2.1 Operating Principles
• The battery must be charged before 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 from 0 °C to +40 °C/
+32 °F to +104 °F. For optimal charging, we recommend charging the bat-
teries 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.
• 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
from the actual battery capacity available.
•
The batteries can be operated from
−
20 °C to +55 °C/
−
4 °F to +131 °F.
•
Low operating temperatures reduce the capacity that can be drawn; high
operating temperatures reduce the service life of the battery.
