Multiple Choice

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 80°F (26.7°C) without the cell voltage falling below a predetermined voltage.
• B)The cold cranking amps rating represents the number of amps that a fully charged battery can deliver at O°F (17.7°C) for 30 seconds while maintaining a voltage above 9.6 volts for a 12V battery.
• C)The cranking amp rating expresses the number of amperes a battery can deliver at 32°F (O°C) 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 80°F can supply before the battery's voltage falls below 10.5 volts.
