| Charging : Cycle Applications: Limit initial current to 1300mA. 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 65mA. 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. |
