DEFINITION

Classification: 205/730

Internal battery action (e.g., using sacrificial anode, etc.):

(under subclass 724) Subject matter in which the object protection is performed without an external source of electrolytic current; usually the electrolytic current is derived from an internal chemical reaction (e.g., galvanic action, using a sacrificial anode, etc.).
