Charging :
Cycle Applications: Limit initial current to 1400mA. Charge until battery
voltage (under charge) reaches 14.40 to 14.70 volts at 68º F (20º C).
Hold at 14.40 to 14.70 volts until current drops to approximately 70mA. Battery
is fully charged under these conditions, and charger should either be
disconnected or switched to "float" voltage. "Float" or "Stand-by Service":
Hold battery across constant voltage source of 13.50 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.
