SPECIFICATIONS
The battery Group Size number, the Cold Cranking Amperage (CCA) rating, and the Reserve Capacity (RC) rating
or Ampere-Hours (AH) rating can be found on the original equipment battery label. Be certain that a replacement
battery has the correct Group Size number, as well as CCA, and RC or AH ratings that equal or exceed the original
equipment specification for the vehicle being serviced. Battery sizes and ratings are discussed in more detail below.
•
Group Size - The outside dimensions and terminal placement of the battery conform to standards established
by the Battery Council International (BCI). Each battery is assigned a BCI Group Size number to help identify
a correctly-sized replacement.
•
Cold Cranking Amperage - The Cold Cranking Amperage (CCA) rating specifies how much current (in
amperes) the battery can deliver for thirty seconds at -18° C (0° F). Terminal voltage must not fall below 7.2
volts during or after the thirty second discharge period. The CCA required is generally higher as engine dis-
placement increases, depending also upon the starter current draw requirements.
•
Reserve Capacity - The Reserve Capacity (RC) rating specifies the time (in minutes) it takes for battery ter-
minal voltage to fall below 10.5 volts, at a discharge rate of 25 amperes. RC is determined with the battery
fully-charged at 26.7° C (80° F). This rating estimates how long the battery might last after a charging system
failure, under minimum electrical load.
•
Ampere-Hours - The Ampere-Hours (AH) rating specifies the current (in amperes) that a battery can deliver
steadily for twenty hours, with the voltage in the battery not falling below 10.5 volts. This rating is also some-
times identified as the twenty-hour discharge rating.
