Battery Duration Experament
By Austin Hall 4th Period
Question
The goal of this experiment was to see if buying name brand batteries would be better than buying generic batteries and how great of a difference there would be.
Research
Batteries have three parts, a negative side (-), a positive side (+), and the electrolyte.The electrolyte is where the chemicals react to generate electricity. The negative and positive sides are hooked up to an electrical circuit. The chemical reactions in the battery causes a build up of electrons at the positive side witch sends a large amount of electric pulses in rapid session. A battery "dies" once all the fuel has been dispersed into electrons.
My reasearch was gathered from the link below:
Hypothesis
If I use different qualities of flashlights than there will be little to no difference between the brands.
Set Up
Step 1: We bought 3 identical flashlights along with 3 batteries of varying qualities: Ever-bright (generic), Ray-ovak (mid range), Duracell (name brand).
Step 2: Next we put the batteries in the flashlights, labeled the flashlights, and made sure all the flashlights worked by flashing them on quickly.
Step 3: Then we turned them all on at the same time and set them on the counter.
Step 4: Lastly we checked when each of them went out and compared the results.
How many hours each battery lasted
End Result Summery
In the end you can see that name brand docent matter to much. I would however like to point out that though Duracell died before Roy-ovak it was significantly brighter so this leads me to believe that they have slimier amounts or chemicals but the reaction for Duracell is using more of it which in turn produces more electrons faster.
