A battery arrangement that minimize battery-to-battery and
battery-to-device contact resistance by rupturing or removing an
insulating contaminant layer on portions of battery terminals that
contact each other or that contact contacts in a battery compartment.
Generally, standard dry cell and miniature 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
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 can be imparted between adjacent
batteries and/or a battery and device contact to facilitate the removal
of the insulating contaminant layer.
