Abstract

The present invention is an efficient and economical battery sealing and supporting device and method. Among a variety of possible applications, the present invention may be utilized as an improved device and method that facilitates the use of cochlear stimulators designed to allow deaf and near deaf patients to experience the sensation of sound waves through electromechanical stimulation. The present invention eliminates the introduction of sweat, body fluid and other contaminants to the battery terminal connection area, which results in corrosion and eventually disables the connected device. Given its broad scope, the technology associated with the present invention is useful in medical and other areas, such as in military applications, hand-held computer and Internet systems and personal entertainment devices.
