There is a lot of variety when it comes to batteries. The basic sizes start really skinny and small and gradually get bigger, beginning with AAA and going up to the big D size. There are also ones that are completely different like the smaller coin cell and button cell varieties designed for small devices like watches and pens. Then there's the 9V, or PP3, battery with is shaped like a rectangular box with connectors that look differently from other kinds of power cells.
Those funny looking connection terminals are referred to as PP3 and are actually built from six tiny 1.5 voltage AAAA batteries. The rectangular box on the outside simply keeps all those tiny cells in place.
The 9V battery was originally created as a power source for transistor radios. Since that was the device's main function in the beginning, you may find individuals that call them transistor batteries even today. However, now they are used to help generate power for a whole bunch of different electronics, not just transistor radios.
Depending on what your need is, a 9V is available in many different versions. While the standard alkaline variety is always
a popular choice, there is a Duracell Procell 9V that was designed for industrial and commercial use. The Procell 9V is sold in bulk and is perfect for powering tools and equipment that gets used and reused all day long. Or one could go with the new lithium power technology that has been proven to power longer, five times more than alkaline. The Procell 9V also has an extended life span so professionals can stock up and not have to worry about their battery losing juice.
For those who are eco-friendly, there are rechargeable 9V batteries that you can use over and over again. This saves both money and landfill space, as well as keeps the container's chemicals from seeping into the environment. The 9V is ideal for smoke detectors, alarms, radio controlled toys, pocket radios, and remote controls. The 9V may seem like the black sheep of the battery family, but has a ton of uses and plenty of great benefits.
