Which of the following statements about battery ratings is true?
A. The ampere-hour rating is defined as the amount of steady current that a fully charged battery can supply for 1 hour at 80ºF (26.7ºC) without the cell voltage falling bellow a predetermined voltage. B. The cold cranking amperage rating represents the number of amps that a fully charged battery can deliver at 0ºF (-17.7ºC) for 30 seconds while maintaining a voltage above 9.6 volts for a 12 volt battery. C. The cranking amperage rating expresses the number of amperes a battery can deliver at 32ºF (0ºC) for 30 seconds and maintain at least 1.2 volts per cell. D. The reserve capacity rating expresses the number of amperes a fully charged battery at 80ºF can supply before the battery's voltage falls below 10.5 volts.
