Key Facts
- California state level: Penal Code section 242 defines battery as a willful and unlawful use of force or violence upon another person.
- California state level: Simple battery under section 243(a) can be punished by up to six months in county jail, a fine of up to $2,000, or both.
- California state level: California defines assault separately as an unlawful attempt, coupled with a present ability, to commit a violent injury on another person.
- California state level: Battery penalties can change based on injury, the person’s status, the relationship involved, and other facts identified by statute.
- California state level: Battery can also describe a civil wrong, but a civil claim and a criminal prosecution follow different legal rules and seek different outcomes.
In California criminal law, battery means a willful and unlawful use of force or violence on another person. The statutory definition appears in Penal Code section 242.
The word “willful” focuses on an intentional act, not necessarily an intent to injure. The controlling charge and jury instructions determine the mental-state question in a particular prosecution.
Battery and assault are separate California offenses
California Penal Code section 240 defines assault as an unlawful attempt, combined with a present ability, to commit a violent injury on another person. Section 242 defines battery through the completed use of force or violence.
This statutory difference explains why assault and battery should not be treated as interchangeable labels. A separate article covers California assault with a deadly weapon, which has its own elements.
Physical injury is not part of the basic definition
Section 242 defines battery by the unlawful use of force or violence rather than by a stated injury requirement. California law separately increases or changes punishment in several circumstances involving injury or particular protected persons.
Penal Code section 243 defines “injury” for specified subdivisions as a physical injury requiring professional medical treatment. It defines “serious bodily injury” as a serious impairment of physical condition and lists examples including loss of consciousness, concussion, bone fracture, and serious disfigurement.
Simple battery and enhanced forms have different consequences
Under section 243(a), simple battery is punishable by a fine not exceeding $2,000, county jail for no more than six months, or both. Other subdivisions provide different punishment when statutory facts are present.
Section 243 includes provisions concerning certain public-safety and health-care workers, serious bodily injury, and specified close relationships. Those provisions contain additional knowledge, injury, status, or relationship requirements that cannot be assumed from the word “battery” alone.
Penal Code section 243.4 separately defines several forms of sexual battery. Its elements and penalties differ from simple battery under sections 242 and 243(a).
Battery can also be a civil tort
Battery is also used in civil law for a claim involving intentional, harmful, or offensive contact. Cornell’s legal encyclopedia distinguishes civil battery from the crime and notes that civil liability can focus on intentional contact without consent.
A civil lawsuit generally seeks a civil remedy, while a criminal case is prosecuted by the government under a criminal statute. One event can raise both questions, but one proceeding does not automatically determine the other.
What a battery charge does and does not establish
A criminal charge is an allegation that a statute was violated. It is not a finding of guilt.
California Courts describes criminal cases as proceedings in which the government charges a person with a crime. The prosecution bears the burden of proving the charge through the criminal process.
The exact section and subdivision matter because “battery charge” can refer to different statutory forms. The charging document, later court rulings, and final judgment answer different questions and should not be collapsed into a single label.
