Cathodically protected battery having sacrificial anode

DETAILED DESCRIPTION Briefly, according to the invention, there is provided a cathodically protected battery comprising a battery cell having positive and negative electrical terminals.
A sacrificial anode is electrically coupled to the battery cell and situated on an external surface of the battery cell.
The sacrificial anode is strategically located so as to be exposed to the corrosive environment, thereby reducing or partially negating the corrosion of the battery electrical terminals.
In an alternate embodiment of the invention, a cathodically protected multicell battery package is created for use in a corrosive environment.
The multicell battery comprises a battery housing and a plurality of cells within the housing.
The cells are electrically coupled together so as to terminate in a positive and a negative terminal.
Electrical contacts are provided on the exterior of the battery housing and the positive and negative terminals of the cells are connected to these contacts.
A sacrificial anode is electrically connected to the cells so as to expose the sacrificial anode to the environment.
In another embodiment of the invention, a battery-powered electrical device is provided with cathodic protection.
The electrical device is contained within a housing along with a battery power source.
A sacrificial anode is electrically coupled to the battery power source and situated so as to expose the anode to the corrosive environment.
In still another embodiment of the invention, a battery-powered communications device is provided for use in a corrosive environment comprising a communications device and a battery package.
The battery package contains a plurality of cells and electrical contacts, and a sacrificial anode situated so as to expose the anode to the environment.
The communications device and the battery package are configured to detachably interconnect the communication device from the battery package by means of sets of battery contacts and power supply terminals.
