BATTERY CHARGING

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.

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.
