Cold Cranking Amps (CCA)
The value in amperes that a new, fully charged battery can deliver at a temperature of -18 °C for 30 seconds before the voltage becomes too low.
The cold start performance indicates whether a battery can provide the necessary power even in winter, when the electrochemical processes are slower. This is important for starter batteries in vehicles with many consumers or when selecting supply batteries that are also to be used at low temperatures.
