Battery arrangement for reducing battery terminal contact resistance

A battery arrangement that minimize battery-to-battery and battery-to-device contact resistance by rupturing or removing insulating contaminant layers on the portions of the battery terminals (106,108,206,208) that contact each other or that contact the device contacts. Generally, standard dry cell (100) and miniature (200) batteries are arranged such that the surface area of the terminals that contact other terminals or device contacts is reduced. A given compression force applied to the serially-aligned batteries in the battery compartment results in a maximum contact pressure sufficient to rupture the insulating contaminant layer at the terminal region that contacts the adjacent terminal or device contact. A relative lateral motion (310,312,410412) can be imparted between adjacent batteries and/or a battery and device contact to facilitate the removal of the insulating contaminant layer.
