Q: A standard automotive battery contains how many cells?
- 3
- 4
- 6
- 8
A: 6

Q: Each cell in a fully charged lead-acid battery produces approximately:
- 1.5 volts
- 2.1 volts
- 3.7 volts
- 6.0 volts
A: 2.1 volts

Q: The active material on the positive plates of a lead-acid battery is:
- Sponge lead (Pb)
- Lead sulfate (PbSO4)
- Lead dioxide (PbO2)
- Sulfuric acid (H2SO4)
A: Lead dioxide (PbO2)

Q: In a lead-acid battery cell, the number of negative plates compared to positive plates is:
- Equal
- One more negative than positive
- One more positive than negative
- Twice as many negative as positive
A: One more negative than positive

Q: Technician A says the battery case is made from polypropylene because it resists sulfuric acid. Technician B says the battery case contains internal partitions that create separate cell compartments. Who is correct?
- Technician A only
- Technician B only
- Both Technician A and Technician B
- Neither Technician A nor Technician B
A: Both Technician A and Technician B

Q: The positive terminal post on an automotive battery is:
- Smaller in diameter than the negative post
- The same diameter as the negative post
- Larger in diameter than the negative post
- Threaded, while the negative post is smooth
A: Larger in diameter than the negative post

Q: What is the primary function of the separator in a lead-acid battery?
- Conduct current between the positive and negative plates
- Store electrolyte for later use
- Prevent plate contact while allowing ion flow
- Regulate the charging voltage
A: Prevent plate contact while allowing ion flow

Q: The electrolyte in a lead-acid battery is a mixture of:
- Hydrochloric acid and water
- Sulfuric acid and water
- Nitric acid and distilled water
- Phosphoric acid and water
A: Sulfuric acid and water

Q: The BCI group size number on a battery label primarily indicates:
- The battery's cold cranking amp rating
- The physical dimensions, terminal location, and polarity
- The number of plates per cell
- The type of electrolyte used (flooded, AGM, or gel)
A: The physical dimensions, terminal location, and polarity

Q: The six cells in a 12-volt battery are connected:
- In parallel to increase amperage
- In series to increase voltage
- In parallel to increase voltage
- In series to increase amperage
A: In series to increase voltage

Q: Technician A says an AGM battery uses a liquid electrolyte that freely covers the plates. Technician B says an AGM battery absorbs the electrolyte into fiberglass mat separators. Who is correct?
- Technician A only
- Technician B only
- Both Technician A and Technician B
- Neither Technician A nor Technician B
A: Technician B only

Q: Which battery rating measures the number of amps a battery can deliver for 30 seconds at 0°F while maintaining at least 7.2 volts?
- CA (Cranking Amps)
- CCA (Cold Cranking Amps)
- RC (Reserve Capacity)
- Ah (Amp-Hours)
A: CCA (Cold Cranking Amps)

Q: A vehicle has a loose battery hold-down. Technician A says this could lead to premature plate damage from vibration. Technician B says a loose hold-down is only a concern during a collision. Who is correct?
- Technician A only
- Technician B only
- Both Technician A and Technician B
- Neither Technician A nor Technician B
A: Technician A only

Q: An AGM battery is commonly used when the battery is mounted in the trunk or passenger compartment because:
- AGM batteries are lighter than flooded batteries
- AGM batteries produce more cranking amps than flooded batteries
- The sealed design reduces the risk of off-gassing into the vehicle interior
- AGM batteries do not require a hold-down
A: The sealed design reduces the risk of off-gassing into the vehicle interior

Q: The plate grid in a lead-acid battery serves which two purposes?
- Stores energy and produces voltage
- Holds active paste and conducts current
- Separates cells and contains electrolyte
- Provides ventilation and prevents corrosion
A: Holds active paste and conducts current
