Cold Cranking Amp (CCA)<\/b><\/td>The rating used in the battery industry to define a battery’s ability to start an engine in cold temperatures. It is the number of amps a new, fully maintained and charged battery can deliver at 0\u00b0F for 30 seconds, while holding a voltage of at least 7.2 volts for a 12 volt battery. The higher the CCA, the more higher the starting power of the battery<\/td><\/tr>
Continuous Discharge Rating (CDR)<\/strong><\/td>Also known as an amp limit, this is the maximum amount of current (amps) that you can continuously draw before the battery heats up to unsafe levels (typically 75&degC \/ 167\u00b0F).<\/td><\/tr>
Cycle<\/b><\/td>In a rechargeable battery a cycle consists of a charge followed by a discharge.<\/td><\/tr>
Dry Cell Battery<\/b><\/td>Batteries that can be mounted in any position because they are completely sealed & won’t leak acid. Most of these bare either AGM (absorbed glass mat) or Gel type batteries.<\/td><\/tr>
Duty Cycle<\/b><\/td>The use pattern for a battery including charge, overcharge, rest and discharge.<\/td><\/tr>
Electrodes<\/b><\/td>An electrical conductor<\/a> used to make contact with a nonmetallic part of a circuit<\/a> (e.g. a semiconductor<\/a>, an electrolyte<\/a> or a vacuum<\/a>.<\/td><\/tr>
Electrolyte<\/b><\/td>Any substance containing free ions<\/a> that behaves as an electrically conductive<\/a> medium, usually when in a solution. Because they generally consist of ions in solution, electrolytes are also known as ionic solutions<\/b>, but molten electrolytes and solid electrolytes<\/a> are also possible.<\/td><\/tr>
Energy Density<\/b><\/td>A term used for the amount of energy<\/a> stored in a given system or region of space per unit, volume, or mass.<\/td><\/tr>
Float<\/b><\/td>Maintaining a battery on a continuous, long-term charge, normally for batteries that sit unused for longer periods.<\/td><\/tr>
Flooded Cell<\/b><\/td>A cell where the electrodes are immersed in a pool of electrolyte.<\/td><\/tr>
Gas Recombination<\/b><\/td>Recycling gases formed within the cell rather then venting them to the atmosphere. This mainly pertains to sealed lead acid battery.<\/td><\/tr>
Leclanch\u00e9 Cell<\/b><\/td>A French electrical engineer chiefly remembered for his invention of the Leclanch\u00e9 cell<\/a>, one of the first modern electrical batteries<\/a> and the forerunner of the modern dry cell<\/a> battery.<\/td><\/tr>
Life<\/b><\/td>The length of acceptable performance received from a battery, measured in years or in charge\/discharge cycles.<\/td><\/tr>
Maintenance-Free Battery<\/b><\/td>A battery that where no electrolytes can be added.<\/td><\/tr>
Open-Circuit Voltage<\/b><\/td>Voltage of a battery with no load applied to it.<\/td><\/tr>

Overcharge<\/b><\/td>The application of charge current after the battery has reached full charge.<\/td><\/tr>
Oxidation<\/b><\/td>Describes the loss<\/i> of electrons<\/a> or an increase<\/i> in oxidation state by a molecule<\/a>, atom<\/a> or ion<\/a>.<\/td><\/tr>
Parallel<\/b><\/td>Interconnecting cells or batteries by joining all like terminals which doubles battery amp hours\/run time & cca (cold cranking amps).<\/td><\/tr>
Plates<\/b><\/td>Lead plates used within a battery to hold a charge.<\/td><\/tr>
Primary Cell<\/b><\/td>Is any kind of electrochemical cell<\/a> in which the electrochemical<\/a> reaction<\/a> is not reversible. A common example of a primary cell is the disposable battery<\/a>.<\/td><\/tr>
Reduction<\/b><\/td>Part of a reduction-oxidation (redox<\/a>) reaction in which atoms have their oxidation number (oxidation state) changed.<\/td><\/tr>
Reserve Capacity<\/b><\/td>The capacity of a battery, measured in minutes, to keep a vehicle operating if the charging system fails.<\/td><\/tr>
Sealed Cell<\/b><\/td>A cell where all reactants are retained within the container. May contain a vent for release during abusive overcharge.<\/td><\/tr>
Secondary Battery<\/b><\/td>A backup or spare battery used to replace the primary battery when discharged.<\/td><\/tr>
Self-Discharge<\/b><\/td>Is a phenomenon in batteries<\/a> in which internal chemical reactions reduce the stored charge of the battery without any connection between the electrodes. Self-discharge decreases the shelf-life<\/a> of batteries and causes them to have less charge than expected when actually put to use.<\/td><\/tr>
Separator<\/b><\/td>Material which provides separation and electrical insulation between plates of opposite polarity.<\/td><\/tr>
Series<\/b><\/td>Interconnecting cells or batteries by connecting the positive terminal of one unit to the negative terminal of the next, which doubles the battery voltage.<\/td><\/tr>
Wound<\/b><\/td>Interior cell construction in which plates are coiled inside.<\/td><\/tr><\/tbody><\/table><\/figure>\n","protected":false},"excerpt":{"rendered":"
