THE FACTORY DEFAULT VALUES FOR CHARGING:
Battery capacity: = 200 Ah (800 Ah if F05 is ON)
Accept Voltage: = 14.4 volts for 12-volt systems (for wet cell batteries)
= 28.8 volts for 24-volt systems (for wet cell batteries)
Charged Current: = 2% (of battery capacity)
Float Voltage: 0.9 V below the Accept Voltage for Liquid electrolyte batteries.
0.6 V below the Accept Voltage for Gel 2 electrolyte batteries.
Ambient Temp: = 70 °F (See Temperature Compensation Table)

IDEAL CHARGE CURVE
The LINK 2000 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, Accept, Float, and Equalize. The
CHARGE cycle supplies full charger output current until the battery reaches the Accept
charging voltage (14.4 V typically). The ACCEPT 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 about every 30 days during
deep-cycling service.
