Preppers  9 volt Battery Hacking

The most common form of nine-volt battery is commonly called the transistor battery, introduced for the early transistor radios. This is a rectangular prism shape with rounded edges and a polarized snap connector at the top. This type is commonly used in pocket radios, smoke detectors, and carbon monoxide detectors to name a few.

Most nine-volt alkaline batteries are constructed of six individual 1.5V cells enclosed in a wrapper.  These cells are slightly smaller than AAAA cells but can be used in their place for some devices, even though they are 3.5 mm shorter.

In an emergency survival situation you could hack a 9 volt battery to power 2 way communication devices and possibly small flashlights.

To open a 9V battery, Find the seam in the metal case and pry up the edge with a screwdriver. Then take a pair of needle nose pliers and peel away the metal. You should just be able to roll up the metal like a sardine can. Then pull off the connector cap to reveal your 6 AAAA batteries. They should just come right out.

AAAA’s are mostly useful for making miniature battery packs or substituting for AAA’s in an emergency. You can do this kind of substitution with any size battery. You just need to find a way to fill in the gaps. You can use coins, nuts, washers or just scrap metal to bridge the electrical connection. To ensure that they fit in the battery slot, the easiest thing to do is wrap them in a few layers of tape. Just keep in mind that they won’t last nearly as long as the larger battery.

    Is it possible to use different sized batteries in portable radios without it causing any problems?

      Yes it is, but keep the volts around the same and if it is a little more it’s fine. Like: 4.5 volt radio can take 4.7 or 5 volts but do not over load it to much.

    That’s really interesting. I may actually get my husband to try that when he gets home.

    Make sure you have the right kind of battery! Once I took apart a regular AA battery just to see what was in it and got squirted right in the eye with battery acid as soon as I breached the case.
