Abstract
A battery comprises a battery cell (110) having positive (160) and negative (140) electrical terminals. The terminals are electrically coupled to the battery cell and situated on an external surface (120) of the battery cell. The exposed surface area of the positive terminal is greater than the exposed surface area of the negative terminal, thereby reducing the corrosion of the battery electrical terminals. A plurality of cells is also configured to form a cathodically protected multicell battery package for use in a corrosive environment. The multicell battery (200) comprises a battery housing (210) and a plurality of cells (250-300) within the housing. The cells are electrically coupled together so as to terminate in positive and negative electrical contacts (221 and 222) on the exterior (220) of the battery housing. The positive and negative terminals of the cells are connected to these contacts, and formed so that the ratio of the areas of the positive/negative contacts is greater than unity.
