Cycle Applications: Limit initial current to 840mA. 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 29mA. 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.
NONSPILLABLE

NOTE: Due to the self-discharge characteristics of this type of battery, it
is imperative that they be charged after 6-9 months of storage, otherwise
permanent loss of capacity might occur as a result of sulfation.
