Charging Cycle Applications: Limit initial current to 19.25A. Charge until battery voltage (under charge)reaches 14.50 to 14.90 volts at 68º F (20º C). Hold at 14.50 to 14.90 volts until currentdrops to approximately 550mA. Battery is fully charged under these conditions, and charger shouldeither be disconnected or switched to "float" voltage. "Float" or "Stand-by Service": Hold battery across constant voltage source of 13.60 to 13.80 volts continuously. When held at this voltage, the battery will seek its own current level and maintain itself in a fully charged condition.
