CHARGING
Cycle Applications: Limit initial current to 22.5A. Charge until battery
voltage (under charge) reaches 14.40 to 14.70 volts at 68oF (20oC). Hold
at 14.40 to 14.70 volts until current drops to approximately 750mA.
“Float” or “Stand-By” Service: Hold battery across constant voltage
source of 13.50 to 13.80 volts continuously.

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.
