Questions and Answers

What is the primary function of a vehicle's battery?

  • To store and supply electricity for the vehicle's electrical systems when the engine is off
  • To operate the starter motor and provide current for the ignition system during engine cranking (correct)
  • To supplement the charging system when the vehicle's electrical load requirements exceed its ability
  • To produce voltage and deliver electrical current

What happens to primary cells according to their recharge ability?

  • They can be recharged indefinitely without any impact on their chemical composition
  • They cannot be recharged as the chemical reaction destroys one of the metals over time (correct)
  • They can be recharged multiple times without any damage to the metals involved
  • They can be recharged, but with reduced efficiency after each recharge cycle

When does a vehicle's battery supply electricity to supplement the charging system?

  • When there is excess electricity being generated by the alternator
  • When the vehicle's electrical load requirements exceed the charging system's ability to produce electricity (correct)
  • When the vehicle is running and all electrical systems are operational
  • When the engine is off and accessories are being operated
