Charging :
Cycle Applications: Limit initial current to 1000mA. Charge until battery
voltage (under charge) reaches 4.80 to 5.00 volts at 68' F (20' C). Hold at
4.80 to 5.00 volts until current drops to approximately 50mA. 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 4.50 to 4.60 volts continuously. When held at
this voltage, the battery will seek its own current level and maintain itself
in a fully charged condition.
