---|---|
S or SS | as pertaining to Concorde Battery Corporation |
Sealed Cells | Cells that are free from routine maintenance and can be operated without regard to position. |
Secondary Battery | A system which is capable of repeated use by employing chemical reactions that are reversible, i.e: the discharged energy may be restored by supplying electrical current to recharge the cell. |
Self Discharge | The decrease in the state-of-charge of a cell or a battery, over a period of time, due to the internal electro-chemical losses. |
Separator | An insulating sheet or other device employed in a storage battery to prevent metallic contact between plates of opposite polarity within a cell. |
Shelf Life | For a dry cell or battery, the period of time (measured from date of manufacture) at a specified storage temperature after which the cell or battery retains a specified percentage of its original energy content (Also refer to Wet Shelf Life). |
Soak Time | The time required for the electrolyte to be absorbed sufficiently into the active materials of the cells after activation to allow the battery or cell to be placed in service. |
Specific Energy | The energy storage ability of a battery on a weight basis, usually expressed in watt hours per pound (or kilogram); sometimes given on a volume basis in watt hours per cubic foot (or liter). |
Specific Gravity (S.G.) | The weight of the electrolyte is compared to the weight of an equal volume of pure water, used to measure the strength or percentage of sulfuric acid in the electrolyte. |
Starved Cell | A cell containing little or no free fluid electrolyte solution; this enables gases to reach electrode surfaces readily, and permits relative high rates of recombination. |
State Of Charge (SOC) | The available ampere-hours in a battery at any given time. State-of-charge is determined by the amount of sulfuric acid remaining in the electrolyte (S.G.) at the time of testing or by the stabilized open-circuit voltage. |
Sulfation | In its common usage, the term refers to the formation of lead sulfate of such physical properties that it is extremely difficult, if not impossible, to reconvert it to active material. |
Swelling | RG Battery cases swell or bulge when the cell vent valves maintain an internal pressure that is greater than the outer (atmospheric) pressure. |
