Charging

Cycle Applications: Limit initial current to 900mA. Charge until battery voltage (under charge) reaches 7.20 to 7.35 volts at 68oF (20oC). Hold at 7.20 to 7.35 volts until current drops to approximately 45mA. 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.
