Method for controlling corrosion on a battery with fractionally sized terminals

A method for controlling corrosion on the contacts of a multicell battery package used in a corrosive environment, comprising:

• providing a housing having positive and negative electrical contacts situated on an external surface, the positive electrical contact having an exposed surface area greater than the exposed surface area of the negative electrical contact;
• providing a plurality of battery cells that are situated in the housing and electrically coupled to the positive and negative electrical contacts;
• and
• placing the multicell battery package in the corrosive environment, such that the positive and negative electrical contacts are exposed to the corrosive environment.

A method for controlling corrosion on the battery terminals of a battery-powered electrical device that is used in corrosive environments, comprising:

• providing a first housing having the electrical device therein;
• providing a battery power source having a least a positive and a negative terminal, the positive terminal having an exposed surface area between 1.1 and about 10 times greater than the exposed surface area of the negative terminal;
• placing the battery power source in the first housing and electrically coupling it to the electrical device;
• and
• placing the battery power source in the corrosive environment, such that the positive and negative terminals are exposed to the corrosive environment.
