How Batteries Work is a new video lesson from TED-Ed. In this lesson students learn about the origins of batteries, how batteries work, the differences between disposable and rechargeable batteries, and why rechargeable batteries eventually cannot be recharged any more. Students watching the video will also see the difference between dry cell and wet cell batteries.

Applications for Education

To extend the lesson on batteries consider using one of the seven resources featured here including the Blobz Guide to Electric Circuits and Squishy Circuits.
