Stacked Batteries

Experiment #3 from Investigating Voltage

Education Level
Elementary School


Did you ever wonder why it takes two batteries stacked together to run a flashlight or why your video game player takes four batteries? Why do batteries need to be put into these devices a certain way? This activity will allow you to explore how all this works by measuring the voltages across different numbers of batteries stacked together.


  • Measure the voltages of batteries as they are stacked together.
  • Compare the voltages of different types of stacked batteries.
  • Draw conclusions about batteries in an electronic device.
