Less of the standard batteries we are familiar with and more of an energy capsule, these batteries contain the kinetically-charged energy of ourselves or our loved ones. They can be preserved and handed down from generation to generation, or, as in absentia prefers, used, causing their energy to be assimilated back into the natural order of things.

They are designed to have a tactile quality, making them soothing to the touch. While many people will prefer to keep them in a special place and perhaps never use them, they are meant to be used, whether they are simply carried around and held every now and then or used for a very specific purpose.
