Charging
Cycle Applications:
Limit initial current to 1.50A. Charge until battery voltage
(under charge) reaches 4.8 to 5.0 volts at 68°F (20°C). Hold at 4.8 to 5.0 volts
until current drops to under 50mA. Battery is fully charged under these conditions,
and charger should be disconnected or switched to “float” voltage.
“Float” or “Stand-By” Service:
Hold battery across constant voltage source of
4.5 to 4.6 volts continuously. When held at this voltage, the battery will seek its
own current level and maintain itself in a fully charged condition.
Note:
Due to the self-discharge characteristics of this type of battery, it is
imperative that they be charged within 6 months of storage, otherwise permanent
loss of capacity might occur as a result of sulfation.
