Number of Cycles
CHARGING
Cycle Applications: Limit initial current to 3.6A. 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 120mA. 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 13.50 to 13.80 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 after 6-9 months of storage, otherwise
permanent loss of capacity might occur as a result of sulfation.

Charge may fail
to restore full
capacity. Do not
let batteries reach
this state.
Charging before
use is necessary
to help recover
full capacity.
Charging is not
necessary unless
100% of capacity
is required.
