Battery is a criminal offense involving unlawful physical contact, distinct from assault which is the fear of such contact.
In the United States, criminal battery, or simply battery, is the use of force against another, resulting in harmful or offensive contact.[1] It is a specific common law misdemeanor, although the term is used more generally to refer to any unlawful offensive physical contact with another person, and may be a misdemeanor or a felony, depending on the circumstances. Battery was defined at common law as “any unlawful touching of the person of another by the aggressor himself, or by a substance put in motion by him.”[2] In most cases, battery is now governed by statute, and its severity is determined by the law of the specific jurisdiction.
