\nThe quantity of electricity measured in ampere-hours (Ah) that can be delivered by a cell or battery under specified conditions.\nAnode<\/strong>
\nThe electrode in an electrochemical cell where oxidation takes place. During discharge, the negative electrode of the cell is the anode. During charge, the positive electrode is the anode.\nBattery or Pack<\/strong>
\nTechnically, two or more electrochemical cells electrically interconnected in an appropriate series\/parallel arrangement to provide the required operating voltage and current levels. Frequently, however, the term “battery” is applied to a single cell.\nBobbin<\/strong>
\nA cylindrical cell design utilizing an internal cylindrical electrode and an external electrode arranged as a sleeve inside the cell container.\nCapacity<\/strong>
\nThe total number of ampere-hours or watt-hours that can be withdrawn from a fully charged cell or battery under specified discharge conditions.\nCathode<\/strong>
\nThe electrode in an electrochemical cell where reduction takes place. During discharge, the positive electrode of the cell is the cathode. During charge in a rechargeable battery, the negative electrode is the cathode.\nCell<\/strong>
\nThe basic electrochemical unit used to generate or store electrical energy.\nConstant Current<\/strong>
\nA battery discharge regime whereby the current drawn during the discharge remains constant.\nCutoff Voltage<\/strong>
\nThe battery voltage at which the discharge is terminated. The cutoff voltage is specified by the battery manufacturer and is generally a function of discharge rate.\nCylindrical Cell<\/strong>
\nA cell in which the positive and negative plates are rolled up and placed into a cylindrical container (as opposed to stacking the plates in a prismatic cell design).\nDischarge<\/strong>
\nThe change from chemical energy of a battery into electrical energy, and the withdrawal of the electrical energy into a load.\nDischarge Rate<\/strong>
\nThe rate, usually expressed in amperes, at which electrical current is taken from the battery.\nDrain<\/strong> <\/a>
\nThe current withdrawn from a battery during discharge.\n
TOP OF PAGE<\/a><\/div>\nElectrode<\/strong>

\nA safety device used for cutting off an electrical current in the event of an abusive condition.\n
TOP OF PAGE<\/a><\/div>\nInternal Impedance<\/strong>
\nThe opposition exhibited by a circuit element (cell or battery) to the flow of an alternating current (A.C.) of a particular frequency as a result of resistance, induction and capacitance.\nInternal Resistance (IR)<\/strong>
\nThe opposition exhibited by a circuit element (cell or battery) to the flow of direct current (D.C.). In a cell, the internal resistance is the sum of the ionic and electronic resistances of the cell components.\nLimiting Current<\/strong>
\nThe maximum current drain under which the particular battery will perform adequately under a continuous drain. The rate is based on whatever drain rate reduces the running voltage to 1.1 volts.\nLithium Battery<\/strong>
\nLithium primary batteries (non-rechargeable) offer high energy density, extremely long shelf life (two to three times that of Alkaline), a wide operating temperature range, and excellent durability. Lithium primaries are available in many chemistries, each with their own particular attributes.\nLithium Manganese Dioxide Battery (LiMnO2)<\/strong>
\nA primary battery (non-rechargeable), the Lithium Manganese Dioxide battery offers high energy density, reliability and excellent shelf life. Less volatile and less costly than Lithium Sulfur Dioxide, LiMnO2 batteries offer a good balance of performance and safety. Their uses include keyless entry systems and memory back up.\nLithium Thionyl Chloride Battery (LiSOCl2)<\/strong>
\nA primary battery (non-rechargeable), the Lithium Thionyl Chloride battery has the highest energy density of all Lithium types. Service life is typically 15 to 20 years. These cells are best suited for applications having low continuous-current and moderate pulse-current requirements. Their long service life and low self-discharge rate make them ideally suited for use in harsh or inaccessible environments like utility monitoring and electronic toll collection.\nLoad Current<\/strong> <\/a>
\nThe discharge current delivered to a battery-powered device.\n
TOP OF PAGE<\/a><\/div>\nMilliampere-hour (mAh)<\/strong>

\nAn electrode or a terminal that has an excess of electrons.\nNominal Voltage<\/strong>
\nThe characteristic operating voltage or rated voltage of a battery.\nOhm<\/strong>
\nA measure of electrical resistance that causes one volt to produce a current of one ampere.\nOpen-Circuit Voltage (OCV)<\/strong> <\/a>
\nThe difference in potential between the terminals of a cell when the circuit is open (no-load condition).\n
TOP OF PAGE<\/a><\/div>\nParallel<\/strong>
\nThe interconnection of cells or batteries where all the like terminals are connected together. This results in increased capacity.\nPassivation<\/strong>
\nThe phenomenon by which a metal, in conditions of thermodynamic instability, remains unattacked because of modified or altered surface conditions.\nPolarity<\/strong>
\nIn electricity, the quality of having two charged poles, one positive and one negative.\nPositive<\/strong>
\nA terminal or electrode that has a shortage of electrons.\nPositive Temperature Coefficient (PTC)<\/strong>
\nA PTC device protects the cell or battery from external short circuits while allowing it to continue functioning after a short circuit is removed.\nPrimary Battery<\/strong>
\nA battery which is not intended to be recharged and is discarded when it has delivered all of its electrical energy. (A non-rechargeable battery.)\nPrismatic Cell<\/strong>
\nThe positive and negative plates are stacked rather than rolled as done in a cylindrical cell.\nPulse Current<\/strong>
\nA periodic current drain of higher than normal drain rates.\nRated Capacity<\/strong>
\nThe number of ampere-hours a battery can deliver under specific conditions (for example, rate of discharge, end voltage, temperature). Rated capacity is usually specified by the battery manufacturer.\nResistance<\/strong> <\/a>
\nThe degree to which the flow of electrons is opposed by the material the electrons must pass through. Resistance is expressed in ohms.\n
TOP OF PAGE<\/a><\/div>\nSafety Vent<\/strong>
\nA safety mechanism designed into a cell that activates under specific conditions of abuse to relieve internal pressure.\nSelf-Discharge<\/strong>
\nThe loss of capacity of a battery during storage due to internal chemical action.\nSeries<\/strong>
\nThe interconnection of cells where the positive terminal of the first is connected to the negative terminal of the second, and so on. This results in increased voltage.\nShelf Life<\/strong>
\nThe duration a cell can be kept in storage under specified conditions and still retain its ability to give a specified performance.\nShort Circuit<\/strong>
\nAn unwanted electrical connection between a negative and positive source. Short circuits can damage the battery and equipment and can cause fire.\nSpiral Wound<\/strong>
\nAn electrode structure of high surface area created by winding the electrodes and separator into a spiral, jelly-roll configuration.\nTemperature Cutoff<\/strong>
\nA safety device which senses temperature in a battery and opens or cuts off the electrical circuit if the specified temperature is exceeded, thus preventing a further rise in temperature.\nTerminal<\/strong>
\nA device at the end of a cell or wire at which a connection to an adjoining cell or wire is established or broken.\nThermistor<\/strong> <\/a>
\nA temperature sensitive resistor usually made from specially processed oxides that are used to sense end of charge temperature rises and terminate high rate charging.\n
TOP OF PAGE<\/a><\/div>\nVoltage<\/strong>
\nA unit of measuring electric potential. Voltage is the difference in electrical energy between two points.\nVoltage Delay<\/strong>
\nTime delay for a battery to deliver the required operating voltage after it is placed under load.\n
