Which batteries will last longer: Energizer, Energizer e2 or Duracell?

I think Energizer e2 will last longer because it has more power than regular Duracell or Energizer batteries.

I play a cd player with two AA Energizer batteries and time how long they last. I follow a schedule and play the cd player at certain times. When the Energizer batteries run out (stop), I do the same thing with the two AA e2 Energizer batteries and then Duracell batteries.

Control Group:
I normally use Energizer batteries.

Variables:
I used Energizer e2 and Duracell batteries.

Energizer e2 lasted 66% longer on average in the cd player than regular Duracell or Energizer cells.

My hypothesis was correct. I guessed that Energizer e2 batteries would last longer because they have more power than any other battery (according to manufacturer's claim). More sets of batteries could have been tested to verify the experiment's results.

"For by Him were all things created, that are in heaven, and that are in Earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by Him, and for Him." Colossians 1:16

God created everything and gave man the ideas of inventing things, like batteries to make our society better. God gave man the right materials to make these things. Batteries help us in many ways by helping things run. Some examples are: they help in health care, education, space exploration and many other things. Even though man invented batteries, we know from Colossians 1:16 that God gave man the right materials and ideas to make things like batteries.
