Charging :
Cycle Applications: Limit initial current to 260mA. Charge until battery
voltage (under charge) reaches 7.20 to 7.35 volts at 68º F (20º C).
Hold at 7.20 to 7.35 volts until current drops to approximately 13mA. 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 6.75 to 6.90 volts continuously.
When held at this voltage, the battery will seek its own current level and
maintain itself in a fully charged condition.
