BatteriesBATTERY OPERATIONSShelfLifeThe shelf life of a battery is the time which a battery may be stored and not lose more than10 percent of its original capacity.ChargeandDischargeThe charge of a battery may refer to as one of two things: (1) the relative state of capacity ofthe battery, or (2) the actual act of applying current flow in the reverse direction to return thebattery to a fully-charged state.Discharge, simply stated, is the act of drawing current from a battery.SummaryBattery operations are summarized below.Battery Operations SummaryThe output voltage of a battery connected in series is equal to the sum of the cellvoltages.A battery that is connected in parallel has the advantage of a greater current-carrying capability.Secondary cells can be recharged; primary cells cannot be recharged.The unit for battery capacity is the ampere-hour.Internal resistance in a battery will decrease the battery voltage when a load isplaced on the battery.Shelf life is a term that is used to measure the time that a battery may sit idleand not lose more than 10 percent of its charge.The charge of a battery may refer to one of two things: (1) the relative state ofcapacity of the battery, or (2) the actual act of applying current flow in thereverse direction to restore the battery to a fully-charged condition.Discharge refers to the act of drawing current from a battery.Rev. 0 Page 13 ES-04
