IDEALCHARGECURVE
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
