Battery Charging
Completely charging wet cell deep-cycle
batteries requires the battery voltage to be
raised beyond what is known as the gassing
point. This is the voltage at which the battery
begins to bubble and gas is given off. If
charging stops short of this point, sulfate is left
on the plates and deterioration of the battery
begins. The gassing point will vary with battery
temperature.
At 77 °F, the gassing point of a 12 volt bat-
tery is about 14.0 volts.
AGM and Gel cell batteries must not be
charged to their gassing point. In fact, high
voltage charging that gasses these batteries
is harmful to them. They typically require a
lower bulk charge voltage. Gel cell batteries
require a higher float voltage than wet cell bat-
teries. Consult the battery manufacturer for
specifications.
BATTERY CHARGING
Freedom Battery Chargers
Freedom battery chargers are designed
to overcome the limitations of conventional
chargers by utilizing three distinct charge
stages, each designed for optimal charging of
wet, gel cell and AGM deep-cycle batteries.
Battery type selection is made on the front panel
of the inverter/charger or through the Remote
Control Panel or a Link Instrument. For more
information on battery type selection, see page
9 or refer to the Remote Control Panel manual.
