Understanding Car Battery Sizes

Car batteries come in a variety of sizes, each designed to meet the specific electrical requirements of a particular vehicle. The size of a car battery is typically measured in terms of its physical dimensions, cold cranking amps (CCA), and reserve capacity (RC). Here are some common car battery sizes:

  • Group 24: This is one of the most common car battery sizes, measuring 10.25 inches long, 6.75 inches wide, and 7.5 inches tall. Group 24 batteries have a CCA rating of around 500-600 amps and an RC rating of around 100-120 minutes.
  • Group 27: This size battery is slightly larger than the Group 24, measuring 12 inches long, 6.75 inches wide, and 7.5 inches tall. Group 27 batteries have a CCA rating of around 600-700 amps and an RC rating of around 120-140 minutes.
  • Group 4D: This is a larger car battery size, measuring 13 inches long, 7 inches wide, and 8 inches tall. Group 4D batteries have a CCA rating of around 800-900 amps and an RC rating of around 140-160 minutes.
  • Group 8D: This is one of the largest car battery sizes, measuring 20 inches long, 10 inches wide, and 10 inches tall. Group 8D batteries have a CCA rating of around 1,000-1,200 amps and an RC rating of around 200-240 minutes.
