DescriptionAlso known as a 049Battery Dimensions:Polarity:Details: 15% extra starting powerAll-round battery for standard useComplete range covering almost 100% of car parcOriginal equipment experience inside The proven Exide Excell battery is an all-rounder for most modern vehicles standard equipment and everyday driving. As every Exide battery the Excell battery also features the robust 3DX grid technology for better electrical performance and longer lifespan. Battery Terminology:Ampere or AmpThe unit of measurement of current flow. One volt placed across a one ohm resistance will cause a current of one Amp to flow.Ampere-hour or AhOne amp for one hour is called an “amp-hour” or Ah. Ah is an indicator of the total energy the battery can store and deliver at its rated voltage. Current multiplied by time in hours equals ampere-hours. A current of one amp for one hour would be one amp-hour. The Ah performance rating of automotive batteries is measured over 20 hours of discharge so a current of 3 amps for 20 hours would be 60 Ah.Cold Cranking Amperes (CCA)The CCA is an indicator of the power the battery can deliver for engine start. Consequently bigger engines usually require higher CCA values to operate. CCA is measured in Amperes under normalised conditions (discharge at -18ºC keeping battery voltage over a minimum value) according to the standard EN50342-1.VoltageAll modern conventional cars use a 12V battery consisting of six cells of 2V per cell. For other applications lead-acid batteries are also available in 6V.
