Chapter 25 - Batteries, Starting, and Charging Systems

A battery high rate discharge (load capacity) test is being performed on a 12-volt battery. Technician A says that a good battery should have a voltage reading higher than 9.6 volts while under load at the end of the 15-second test. Technician B says that a battery should be discharged (loaded to two times its CCA rating). which technician is correct

• Tech A

• Tech B

• Both techs are correct

• Neither tech is correct

When Jump Starting a vehicle, _____________.

• Conductance Tester

• Load Tester

• Ammeter tester

A battery should be charged at what rate?

• High or fast depending on the capacity of the charger

• at a rate of 1%of the CCA rating of the battery

• at a rate that does not cause the battery to get hotter than 125*F

• Both B and C

Which battery rating is used mostly when testing a battery to see if it is performing normally? (be careful!)

• Cranking Amps(CA)

• Cold Cranking Amps(CCA)

• Ampere-Hour Rating(Ah)

• Reserve Capacity(RC)
