THE FACTORY DEFAULT VALUES FOR CHARGING:
Battery capacity = 200 Ahrs (800 Ahrs if F05 is ON)
Acceptance Voltage= 14.4 Volts for 12 Volt systems
= 28.8 Volts for 24 Volt systems
Charged Current %= 2% (of battery capacity)
Float Voltage: 0.9V below the Acceptance Voltage for Liquid electrolyte batteries.
0.6V below the Acceptance Voltage for Gelled electrolyte batteries.

IDEAL CHARGE CURVE
The LINK 2000 transmits critical battery state of charge information to the
Freedom inverter/charger (and controls the alternator with the Link 200-R option). 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 "equalization" of liquid electrolyte batteries for maximum capacity and
life. The batteries should be Equalized every 30 days during deep cycling service.
