Which of the following statements about battery rating 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 80o F (26.7o 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 0o F(-17.7o C) for 30 seconds while maintaining a voltage above 9.6 volts for a 12 volt battery. c.The craking amp rating expresses that number of amperes a battery' can deliver at 32o F (0o C) for 30 seconds and maintain at least 1.2 volts percell. d.The reserve capacity ratng expresses the number of amperes a fully charged battery at 80o F can supply before the battery's voltage falls below 10.5 volts.
