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.
