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.

Question

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.
