We are all familiar with the range of alkaline batteries in all of their sizes, voltages, and capacities. The most common of these portable storage devices are the D, C, AA, and AAA. But, there are less well known types used as well. Type N is fairly common but not as popular. Another one that is widely used but less frequently available is the AAAA (LR61) or usually called the quadruple A. These smaller than AAA cells, are used in computer styli, laser pointers, LED flashlights, and headphone amplifiers. I use them when I need a smaller physical battery than the AAA but with reasonable milliamp/hour capacity. But, I have never bought one! They are not generally available in local stores, so some time ago I found that the Duracell 9 Volt batteries had six quadruple A batteries inside. So, the resulting video shows how to extricate these little gems easily and save some money as well. I have not tried other alkaline 9 volt batteries but some may be identical. If you have found other sources of batteries with these cells please comment.
