Charging :
Cycle Applications: Limit initial current to 15A. 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 750mA. 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.
