Aux 1 Unit 16 Q1

1 / 10

When is a boost charge typically used?

A) During routine maintenance

B) When a battery is deeply discharged and needs to be recharged quickly to return to service

C) When the battery is not in use

D) When the battery is fully charged

2 / 10

Why is a float charge particularly useful in standby power applications?

A) It allows the battery to discharge slowly

C) It increases the charging time

D) It reduces the battery's voltage

B) It ensures the battery is always fully charged and ready to provide power when needed without overcharging

3 / 10

How does trickle charging affect the battery's lifespan?

A) It shortens the battery's lifespan

C) It causes the battery to overheat

D) It rapidly discharges the battery

B) It maintains the battery's charge without overcharging, thus helping to prolong the battery's lifespan

4 / 10

What is the key difference between a float charge and a trickle charge?

B) A float charge is used to rapidly charge the battery

D) A float charge is only used for new batteries

A) A float charge is applied after the battery is fully charged, maintaining the battery at full charge by supplying only the current needed to counteract self-discharge

C) A float charge discharges the battery over time

5 / 10

Why is a slow charge considered beneficial for storage batteries?

D) It allows the battery to discharge completely before recharging

B) It minimizes heat generation and reduces the risk of overcharging, thus prolonging the battery's lifespan

A) It fully charges the battery in a very short time

C) It increases the battery's charging speed

6 / 10

What is a boost charge in the context of storage batteries?

D) A low-current charge applied over a long period

C) A charge given to a battery while it is in use

A) A fast and high-current charge given to a battery to quickly restore its capacity

B) A slow charge that maintains the battery at full charge

7 / 10

What is the main characteristic of a slow charge for a storage battery?

A) It applies a high current to the battery

D) It discharges the battery slowly

B) It uses a low current over an extended period to recharge the battery gently

C) It charges the battery while it is in use

8 / 10

What is a potential risk associated with performing a boost charge on a storage battery?

C) The battery becoming more efficient

A) Overheating and potential damage to the battery due to the high current applied during the charge

B) The battery charge level dropping

D) The battery losing its capacity to hold a charge

9 / 10

When is trickle charging most commonly used?

D) When the battery needs to be discharged

C) When the battery is completely discharged

B) When the battery is stored for extended periods or used intermittently

A) When the battery is in heavy use

10 / 10

What is the purpose of a trickle charge for a storage battery?

B) To maintain the battery at full charge by applying a very low current continuously

C) To discharge the battery slowly

D) To prepare the battery for storage

A) To charge the battery quickly
