Exide invented the first EFB battery in 2008 helping European car manufacturers to reduce fuel consumption and emissions for small to mid-sized cars. Their technology is now considered the most advanced in the industry. The latest-generation EFB battery offers significantly improved charge acceptance and cycle life a result of key breakthroughs in lead alloys and unique carbon additives that came from Exide’s R&D efforts. Exide’s Start-Stop EFB batteries enable Start-Stop regenerative braking and other powerful fuel-saving features.
Ampere or Amp
The 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 Ah
One 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.
All 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.
