Why batteries come in so many shapes and sizes

Turns out a nine-volt battery is basically just a bunch of smaller batteries in a trench coat.

Also, you may have noticed that we said AAA when we meant AAAA batteries. Gold star for all who caught it ⭐. What we should have said is that a 9-volt is six AAAAs in a trench coat!

Basically small batteries store less energy, but weigh less and take up less space. It's a tradeoff depending on the product's size constraint, peak need and with consideration for a reasonable operational duration. The voltage variation in batteries is tied to voltage standardization of electrical components in the device and with some historical constraints as well.

thanks for the quick lesson; it's "we" and not "us" - just sayin'

Next week, why do *animals* come in different shapes & sizes? 🤦‍♂️

Varying human appetites?
