Batteries

Operating Principles

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
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 indic-
ated on the charger or on a Leica Geosystems product deviates signific-
antly 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.
