CH.13 ASE

1.Technician A says that batteries should be the starting point when diagnosing complaints such as hard starting, slow cranking, or no start. Technician B says that dirt on top of the battery does not cause premature self-discharge of the battery. Who is correct?

2.Technician A says you should never create a low-resistance connection or short across the battery terminals. Technician B says to always wear protective clothing such as rubber gloves and goggles or full-face shields when handling batteries. Who is correct?

3.Technician A says that a low electrolyte level is a common reason for sulfation. Technician B says that high ambient temperature is a common reason for sulfation. Who is correct?

4.Technician A says that batteries may slowly fail over time through due to the loss of a cell or open circuits within the internal connections. Technician B says that batteries may slowly fail over time through the gradual loss of capacity caused by plate deterioration. Who is correct?

5.Technician A says that, if electrolyte is lost due to spillage, then the battery should be topped up with electrolyte. Technician B says that, if electrolyte level is lost through evaporation, then tap water should be added. Who is correct?

6.Technician A says to always coat battery terminals with chassis grease to prevent corrosion. Technician B says that all slide mechanisms on battery trays should work properly. Who is correct?

7.Technician A says that a fully charged battery should have an open-circuit voltage of 12.25 volts. Technician B says that, if the battery has been recently charged, a light load applied to the battery for a few minutes will remove a surface charge. Who is correct?

8.Technician A says that a conductance test determines the battery's ability to conduct current. Technician B says that batteries must be fully charged to test battery conductance. Who is correct?

9.Technician A says that the load test determines the ability of a battery to deliver cranking amperage and is based on the battery CCA rating. Technician B says that a battery must be at least 95% charged to perform a capacity test, so SOC must be first evaluated before proceeding. Who is correct?

10.Technician A says that all modern vehicles have a small amount of current draw when the ignition is turned off. Technician B says that this charge is used to run some of the vehicle systems, such as various modules making up the onboard vehicle network. Who is correct?
