True or False? A fully charged new battery willhave a low conductance reading.
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.
Which of the following statements about batterytypes is not true?a. Deep cycle batteries are designed to gothrough many charge and discharge cycles.b. A low-maintenance battery is a heavy-dutyversion of a normal lead-acid battery.c. Maintenance-free batteries require externalholes or vent caps.d. In a gel cell battery, gassing is minimized andvents are not needed.
