The
12 volt sealed gelled-electrolyte (gel-cell) lead-acid
battery is the gaging station power source recommended by
the USGS. Even if the gauge house has AC power available,
batteries are used because of their reliability during
storm and flood events. The battery is a general purpose,
rechargeable, gel battery. The battery's sealed case is
made of high impact polystyrene which allows the battery
to be operated or stored in any position without leakage.
The battery has push on terminals for easy connections.
Gel cell batteries have a life span from 3 to 5 years
if properly cared for. Extended life can be gained by
trickle charging the battery with a small solar panel or
AC charger.
Four commonly used models are available with the
following specifications.
