4.7 Batteries
4.7.1 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 environment is only indoor conditional and temperature range for charging
is between 0 °C to +40 °C/+32 °F to +104 °F. For optimal charging, we recommend charg-
ing 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 recom-
mended by GeoMax, 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
GeoMax 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 temper-
atures reduce the service life of the battery.
