A “battery” is defined as any device that can store energy for later use. Lead plates covered with an electrolyte provide the “storage” for the chemical energy produced by an outside source such as the converter or battery charger. This energy is routed through the distribution center through automotive fuses with a positive wire going to the appliance or component, and a negative wire going to a ground source.
