MAIN COMPONENTS OF AUTOMOTIVE BATTERIES

I. Learning Competency and Code

LO1. Explain the operation and safe handling of different types of batteries
(TLE_IAAS9-12AB-Ia-d-1)

II. Objective/s
After going through this Learning Activity Sheet, you should be able to:
1. Identify main components of batteries

III. Background Information

An automotive battery is a device that converts chemical energy into
electricity. It uses chemicals to produce electricity, the amount of electricity it can
produce is limited. As the chemical in the battery is depleted the battery runs down
and is discharged. It can be recharged by supplying it with electric current from the
vehicle alternator or from a battery charger. The depleted chemicals are restored to
their original condition as the battery becomes recharged.

Its components are;

1. Battery case - a molded plastic that provides enclosure to the battery parts.
2. Terminal posts – a round metal terminals sticking out of the top of the battery
cover. Battery has two (2) terminal posts that protrude off the top side of the
battery. One terminal is positive, marked with red paint and a (+) symbol, the
other is negative and may be black or green in color. It normally has a (-)
symbol on or near it.
3. Vent caps – it covers the vent holes on top of the battery. These caps serve
two (2) purposes:
a.) they permit the checking and maintenance of water and acid levels,
and
b.) provide a vent for the escape of gases formed when the battery is
charging.

1
 4. Battery cover – bonded to the top of the battery case. It seals the top of the
case and provides an opening above each battery cell for battery caps or a cell
cover.
5. Cells – a metal electrode (metal plates that can donate and receive electrons)
that generate an electric charge.
6. Cell connectors – heavy cast alloy metal straps are welded to the negative
terminal of one cell and the positive terminal of the adjoining cell until all six
cells are connected in series so that electricity can be conducted along the
length of the battery.
7. Cell partitions - part of the case, the partitions separate each cell.
8. Plates – positive and negative plates have a grid framework on antimony and
lead alloy. Active materials are pasted to the grid. The number and size of the
plates determine current capability, batteries with large plates or many plates
produce more current than batteries with small plates or few plates.
9. Separators – thin, porous insulators (woven glass or plastic envelopes) are
placed between positive and negative plates. They allow passage of
electrolyte, yet prevent the plates from touching or shorting out.
10. Electrolyte – a mixture of sulfuric acid (H2SO4) and water (H20). It reacts
chemically with the active materials in the plates to create an electrical pressure
(voltage). And, it conducts the electrical current produced by that pressure from
plate to plate.

Functions of the battery:

The functions of the battery are to:
1. Operate the starter motor
2. Provide current for the ignition systems and electrical accessories when the
engine is not operating.

2
3. Supply power for the lighting systems and electrical accessories when the engine
is not operating.
4. Act as a voltage stabilizer for the complete electrical system.
5. Provide current when the electrical demand of the vehicle exceeds the output of
the charging system.

IV. Directions / Instructions

Now you are done with the discussion, next is to answer the given activities,
here are some tips/guides for you.
1. Read and follow instructions carefully.
2. Do all activities diligently. Do not leave an activity/activities unanswered.
3. Do not hurry. It is better to slow but sure than to hurry and miss the
concepts you are supposed to learn.
4. Be honest. Do not turn to the Answer Key page unless you are done with
the activity.
5. You can check your answers after finished the activity or entire activities to
know how much have you gained from the lesson.
Note: Write your answer directly in the Self-Learning Activity Sheet (SLAS).
Use only separate sheet if necessary.
