Which part of this do you disagree with? It's from Findlaw.
Battery is a general intent offense. This means that the actor need not intend the specific harm that will result from the unwanted contact, but only to commit an act of unwanted contact. This also means that gross negligence or even recklessness may provide the required intent or (in criminal matters) mens rea to find a battery...
...if ... there is only the slightest intentional touching of another, which is harmful or offensive and also non-consensual (such as reaching out and touching a woman's thigh), a battery has occurred...
Non-consensual contact may be made with either a person or that person's extended personality. This means that if one person leans forward and yanks the jewelry necklace off another, a battery has occurred, even though the first person never actually touched the neck of the second person. If this act was preceded with an intent to cause the other to apprehend an impending violent yank of the necklace, both an assault and a battery have occurred...
A plaintiff or complainant in a case for battery does not have to prove an actual physical injury. Rather, the plaintiff must prove an unlawful and unpermitted contact with his or her person or property in a harmful or offensive manner. This, in and of itself, is deemed injurious. As in the case of the Texas hotel manager above, the harm may be offensive rather than physical, but equally worthy of compensation under the law.
