3.5.1 Operating Principles
Charging / first-
time use
•
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.
•
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 GeoMax, it is not possible to charge the battery
if 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 indi-
cated on the charger or on a GeoMax product deviates significantly form
the actual battery capacity available.
Operation /
Discharging
•
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.
