A battery load test is being performed on a 12 volt battery.
Technician A says that a good battery should have a voltage reading of higher than 9.6 volts
while under load at the end of the 15-second test. Technician B says that a battery conductance
tester is often used to load the battery to two times the CCA rating of the battery. Who is right?
A
