Today we're going to learn how to easily make our own batteries from very inexpensive household materials.
An AA battery is a standard size cylindrical battery commonly used in portable electronic devices. The exact terminal voltage and capacity of an AA size battery depends on the cell chemistry but are usually rated at or near 1.5 volts.
An AA cell measures 49.2–50.5 mm in length, including the terminal and 13.5–14.5 mm in diameter.
AA batteries account for over 50% of general battery sales and the average price of a quality AA battery can range from $0.59 to as much as $1.42 or more.
Think this would be helpful in an emergency? Is this a viable and renewable source of energy? Would this be a good way to teach kids about science?
