Which battery
lasts the longest?
How can power be increased? |

Introduction:
Today batteries are used in millions of portable electronic equipments such as
watches, cameras, calculators, radios, cellular phones, flashlights, computers, remote controls and many more.
Advertisements
on T.V. often suggest certain brand batteries last longer.
Now I have to find out for myself. And I also need to know if
there is a real difference between battery lives of different
brands, what is the reason for that?

Project
description:
This project has all
the benefits of a simple, small and educational Science Project
for Intermediate students.
In this project you are trying to find out what battery lasts
the longest. You will also try to determine if the cost of the
battery has anything to do with the power it has. While making a basic electric circuit, you will test different
batteries for battery life. During this experiment you will learn
about electricity and technical differences among different batteries.
Your presentation will include an actual test device that you
have made.
Also learn about the structure of a battery and how it produces
electricity. Compare samples of batteries available in the market.
Measure the amount of time that it takes for these batteries
to discharge with an equal load. This project can be worked on by elementary,
intermediate and senior students. At elementary and intermediate
level you just measure how long the battery lasts. In senior
level you will also measure the amount of energy produced by
each battery. |
