Abstract
An anode protection device and method are provided. The method includes placing a sacrificial anode in proximity to the positive and negative contacts to shield or distort the field therebetween which provides preferential corrosion of the sacrificial anode, instead of the anode. The protection device is a sacrificial anode having various forms and placed in different configurations. In one form the sacrificial anode is a plate. In another form the sacrificial anode is a ring placed around either the positive contact or negative contact to provide a shield between the negative and positive contacts. In a further device embodiment, the sacrificial anodic plate can be welded to the aluminum case of a rechargeable battery of a behind-the-ear (BTE) hearing device.
