CHARGING Cycle Applications: Limit initial current to 1.6A. Charge until battery voltage (under charge) reaches 14.40 to 14.70 volts at 68oF (20oC). Hold at 14.40 to 14.70 volts until current drops to approximately 54mA. “Float” or “Stand-By” Service: Hold battery across constant voltage source of 13.50 to 13.80 volts continuously.
