Exam 5: Automotive Batteriesbattery Diagnosis and Service

A load of 325 amperes for a 650 cold cranking amperage battery is the correct capacity load test amperage.

A 450 cold cranking amperage battery is being load tested. What will the correct load be?

Which of the following statements about NiMH cells is NOT true?

Technician A says a 12.6-volt open circuit voltage reading indicates a fully charged battery. Technician B says a corrected hydrometer reading of 1.265 indicates that a battery cell has the proper electrolyte specific gravity. Who is correct?

What rating indicates the battery's ability to deliver a specified amount of current to start an engine at low ambient temperatures?

What test is being performed in the figure below?

The HV battery is charged when the vehicle is driven, or when the engine is running. This is the ____ method of charging the HV battery pack.

When using a battery starter tester to make a battery load test, turn the control knob to draw battery current at a rate equal to which of the following?

Properly sealed NiMH batteries that are not leaking are considered dry cell batteries and are not ____.

During the capacity test the voltage reads 10.6 volts. This indicates that the battery must be replaced.

Electrical energy is produced in the battery by the chemical reaction that occurs between two dissimilar plates that are immersed in a(n) ____ solution.

What type of battery uses separators that hold a gel-type material in place of liquid electrolyte.

Describe the main purposes of the vehicle battery.

Unlike conventional capacitors that use a dielectric, the ultra-capacitors use a(n) ____.

Technician A says a fully charged battery will not freeze as easily as a discharged one. Technician B says the specific gravity of a fully discharged battery is around 1.100. Who is correct?

Battery electrolyte is a mixture of water and what other element?

Technician A says the current capacity rating of a battery depends on the types of materials used in the construction of the battery. Technician B says the amount of electrical energy that a battery is capable of producing depends on the size, weight, and active area of the plates. Who is correct?

Which of the following is an indication of how well a battery would perform if the charging system of a vehicle failed?

The condition of a battery cable end (where it connects to the battery post) is questionable. Technician A says a battery leakage test will determine the quality of the connection. Technician B says a battery terminal voltage drop test can be used to determine the quality of the connection. Who is correct?

A three-minute charge test can be used instead of a hydrometer to test a cell's state of charge.
