Question

Technician A says that the reserve rating of a battery is the amount of steady current that a fully charged battery can supply for 20 hours without the voltage falling below 10.5 volts. Technician B says that ampere-hour ratings state how many hours the battery is capable of supplying 25 amperes. Who is correct?

Answer 1

Neither A nor B

Step-by-step explanation:

Reserve capacity is the number of minutes that a new, fully charged battery can discharge continuously and maintain a terminal voltage equal to or greater than 1.75 volts per cell.

An ampere-hour is an electric charge unit and its abbreviation is Ah.

It measures the amount of electric charge flowing through a battery in the case that amount supplies a current of 1 amp for 1 hour.
