Battery is generally a harmful or offensive contact with another person, without the person’s consent. Battery may be the basis for a criminal charge or offense. The definition and penalties for battery vary from state to state, and are usually located in a state's penal or criminal code (statutes). In some states the crimes of assault and battery are merged into one criminal offense.

Battery is also recognized in tort law as an intentional tort, and may result in civil liability (money damages) in a lawsuit against a person who commits battery.

In Nevada, battery is defined as any willful and unlawful use of force or violence upon the person of another. It is considered a criminal offense under Nevada Revised Statutes (NRS) 200.481. The severity of the charge can range from a misdemeanor to a felony, depending on factors such as the presence of a weapon, the extent of injury caused, and whether the victim is a protected individual (e.g., a police officer, healthcare provider, or school employee). Penalties can include fines, imprisonment, and mandatory community service. Additionally, Nevada law allows for the crime of assault and battery to be combined into one charge in certain circumstances. Beyond criminal charges, a person who commits battery may also face civil liability and be required to pay monetary damages to the victim. This is governed by tort law, where battery is considered an intentional tort, and the victim can file a lawsuit seeking compensation for their injuries and suffering.
