Types of batteries and how they work, part 1 went into a bit of battery history followed by a general overview of how batteries work with a discussion on battery capacity and ways to connect them. Next, the post went into some details of primary battery types and chemistry.

This time around, we’re going to talk about secondary batteries, also known as rechargeable batteries. But first, I wanted to talk a bit more about battery capacity to remove any lingering confusion from the last post.

There are many different types of batteries, and they are an invention that, believe it or not, dates back several thousand years.
