How Much Fuel is in Your Battery


How Much Fuel is in Your Battery

I wrote this article back in 2017 for the Albury Club, deals with state of charge explaining many factors when dealing with primary cells.
Useful read for the beginner in understanding batteries and their properties.

"A battery is a store of energy, it can be considered as a container of water that is either full or
empty, with water container it’s easy to determine how much water you have left in the container.
Similarly on many batteries with the exception of Mercury batteries, the terminal voltage can be
an indication of the state of charge, this is not a very accurate method to determine the stored
charge, and there are many factors that make this method unreliable.
(This article is about secondary cells, primary cells are only mentioned as a point of reference.
Primary Cells cant be charged, where Secondary Cells can't)"
