CH.11 REVIEW

1.Which of the following is correct concerning battery classifications?

Primary battery: chemical reactions are not reversible, and the battery cannot be recharged.

Secondary battery: rechargeable

Both Primary battery: chemical reactions are not reversible, and the battery cannot be recharged and Secondary battery: rechargeable

Neither Both Primary battery: chemical reactions are not reversible, and the battery cannot be recharged nor Secondary battery: rechargeable

2.Which of the following is correct concerning types and classification of batteries?

Batteries are classified according to what they are used for and how they are made.

Batteries are classified by the type of plate material and chemistry used to produce current.

Both Batteries are classified according to what they are used for and how they are made and Batteries are classified by the type of plate material and chemistry used to produce current.

Neither Batteries are classified according to what they are used for and how they are made nor Batteries are classified by the type of plate material and chemistry used to produce current.

3.Which of the following statements is correct concerning deep cycle-deep discharge batteries?

Deep cycle batteries are used to deliver a lower, steady level of power for a much longer period of time than an SLI type battery.

Battery plate construction and charging and discharging characteristics of deep cycle batteries are different from SLI type batteries.

In heavy vehicles, deep cycle batteries are used to supply current to constantly powered accessories, such as driver and vehicle communication devices.

All of the choices are correct.

5.Which of the following statements is correct concerning separator plates?

To prevent the battery positive and negative plate from touching and short circuiting, separator plates are placed between each plate in every cell.

Separator plates are very thin, porous, glass-fiber plates allowing electrolyte to diffuse freely throughout the cell and at the same time prevent plate contact.

Both To prevent the battery positive and negative plate from touching and short circuiting, separator plates are placed between each plate in every cell and Separator plates are very thin, porous, glass-fiber plates allowing electrolyte to diffuse freely throughout the cell and at the same time prevent plate contact.

Neither To prevent the battery positive and negative plate from touching and short circuiting, separator plates are placed between each plate in every cell nor Separator plates are very thin, porous, glass-fiber plates allowing electrolyte to diffuse freely throughout the cell and at the same time prevent plate contact.

7.Which of the following is correct concerning multiple-battery configurations?

Batteries can be connected together to supply either more amperage or more voltage.

Diesel engines, which require more cranking torque, will either connect batteries in parallel, to supply more cranking amperage, or in series to supply higher voltage.

Both Batteries can be connected together to supply either more amperage or more voltage and Diesel engines, which require more cranking torque, will either connect batteries in parallel, to supply more cranking amperage, or in series to supply higher voltage.

Neither Batteries can be connected together to supply either more amperage or more voltage nor Diesel engines, which require more cranking torque, will either connect batteries in parallel, to supply more cranking amperage, or in series to supply higher voltage.

8.Which of the following statements is correct concerning battery selection?

The CCA rating of the battery is the most important rating considered when selecting batteries.

In colder weather, engines are also harder to crank due to increased resistance from oil thickening.

BCI estimates diesel engines require 220% to 300% more battery power than a similar gasoline engine.

All of the choices are correct.

9.Which of the following is NOT correct concerning the internal resistance of batteries?

All electrical devices have internal resistance- even batteries.

A battery's internal resistance determines how quickly a battery can be charged or discharged.

Newer lithium batteries have a lower internal resistance than that of a lead-acid battery.

Newer lithium batteries cost about the same as the standard lead-acid battery.

10.Which of the following is NOT correct concerning low- and no-maintenance batteries?

The low- or no-maintenance battery uses less water.

The low- or no-maintenance battery has a longer life expectancy.

The low- or no-maintenance battery has less grid corrosion.

The low- or no-maintenance battery is more quickly discharged by parasitic losses.
