THE IDEAL CHARGE CURVE
The
Link 1000
transmits critical battery state of charge information to the
Freedom
inverter/charger. This enables the charger to conform to our proven Ideal
Charge Curve with four basic cycles; CHARGE, ACCEPTANCE, FLOAT, and
EQUALIZE.
The CHARGE cycle supplies full charger output current until the battery reaches
the Acceptance charging voltage (14.4V typ.). The ACCEPTANCE cycle continues until
the battery is accepting only a small amount of current. The battery is now full. During
the FLOAT cycle the voltage is lowered to maintain the batteries, without water
consumption, for long life. The EQUALIZE cycle allows for periodic "equalizing" of
liquid electrolyte batteries for maximum capacity and life. The batteries should be
Equalized every 30 days during deep cycling service.
