CA = battery's capacity
Cell voltage is different than battery's voltage because a battery can have one or more cells.

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.

Cell charge voltage (V/Cell)
“Float” or “Stand-By” Service: Hold battery across
constant voltage source of 13.5 to 13.8 volts continuously.
When held at this voltage, the battery will seek its own
current level and maintain itself in a fully charged condition.
140
Charge current (CA)
Cycle Applications: Limit initial current to 2.10A. Charge
until battery voltage (under charge) reaches 14.4 to 14.7
volts at 68°F (20°C). Hold at 14.4 to 14.7 volts until current
drops to under 70mA. Battery is fully charged under
these conditions, and charger should be disconnected or
switched to “float” voltage.
