Cold Cranking Amps

The measurement of cranking amperes a battery can deliver over a period of 30 seconds at 0°F (-18°C). Commonly used to rate automotive batteries, it is not usually used to rate motorcycle batteries. Motorcycle batteries are rated in Amp/hours (A/h), that is, how many hours can a fully charged battery supply one amp of current to a load. The larger a motorcycle battery is physically, the greater its Amp/hour capacity.
