Technician A says the reserve capacity rating of a battery is the amount of steady current that a fully charged battery can supply for 20 hours without the voltage dropping below 10.5 volts. Technician B says an ampere-hour rating states how many hours the battery is capable of supplying 25 amperes. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

The reserve capacity rating of a battery actually refers to the number of minutes a fully charged battery at 80°F can discharge 25 amperes until the voltage falls below 10.5 volts. The ampere-hour rating is a measure of the battery's capacity, indicating how many amps a battery can deliver over a specific period (usually 20 hours), not specifically 25 amperes for an unspecified number of hours.
