Overcharge - The forcing of current through a cell after all the active material has been converted to the charged state, that is, continued charging after reaching 100 percent state-of-charge.
Shelf Life - The duration of storage under specified conditions at the end of which the battery still retains the ability to give a specified performance.
Current Drain - The current withdrawn from a battery during discharge.
Voltage Delay - Time delay for a battery to deliver the required operating voltage after it is placed under load.
Microsecond - 1,000,000th of a second (mS).
Hourly Rate (also see C-Rate) - A discharge rate, in amperes, of a battery which will deliver the specified hours of service to a given cutoff voltage.
Earthing system TN - Earthing system in which the exposed conductive parts are interconnected and connected to the neutral. The neutral is connected to the earth. The installation must be de-energized immediately in the event of an insulation fault.
