A Diagram of All the Batteries
If parenthood has taught me anything, it’s that when your kid’s toy needs a battery, you will not have the right size. This is a simple fact of life.

The natural next step was of course to look up battery sizes and chart all of them.

Life expectancy changes
The data goes back to 1960 and up to the most current estimates for 2009. Each line represents a country.
