Cold Cranking Amps is a rating used to give an approximation of a battery’s ability to start an engine in cold temperatures. The higher the CCA rating, the greater the potential starting power of the battery in colder weather. Braille Battery’s are tested using conductance testing which is an approximation of BCI testing. The BCI rating is the number of amps a new, fully charged battery can deliver at 0° Farenheit for 30 seconds, while maintaining a voltage of at least 7.2 volts, for a 12 volt battery using a draw down test. Since this type of testing can shorten the life of a battery, Braille’s batteries are individually tested prior to shipping using the conductance method. This method is much faster and less destructive to batteries.
-NOTE: All cranking performance ratings are based on calculations of data collected from conductance testing. For more information about this method, please click here.
