Assault & Battery

What Is the Difference Between Assault and Battery?

They’re separate crimes, and the distinction surprises most people.

Assault — Penal Code § 240. An unlawful attempt, coupled with the present ability, to commit a violent injury on another person. No contact is required. Swinging and missing is assault. So is raising a fist in a way that makes contact imminent and possible.

Battery — Penal Code § 242. Any willful and unlawful use of force or violence upon another person. No injury is required. An unwanted shove, grab, or push is battery even if nothing is hurt and nothing is bruised.

Put simply: assault is the attempt, battery is the contact. Because a completed battery usually begins as an assault, prosecutors routinely file both from a single incident. That isn’t double jeopardy — it’s standard charging practice, and it means beating one count doesn’t automatically end the case.

Aggravated Assault and Battery Charges

The base offenses are misdemeanors. Several related charges are far more serious.

Assault With a Deadly Weapon — Penal Code § 245(a)(1)

Assault committed with a weapon, or with force likely to produce great bodily injury. This is a wobbler — chargeable as a felony or a misdemeanor — and when charged as a felony it can qualify as a strike under California’s Three Strikes law.

“Deadly weapon” is broader than most people expect. Beyond firearms and knives, courts have found bottles, vehicles, boots, and household objects to qualify depending on how they were used.

Assault by Means Likely to Produce Great Bodily Injury — Penal Code § 245(a)(4)

No weapon required. This charge covers unarmed force serious enough that significant injury was likely — repeated strikes, kicks, or an attack on someone unable to defend themselves.

Battery With Serious Bodily Injury — Penal Code § 243(d)

Sometimes called aggravated battery. A wobbler that applies when the battery caused serious injury. What counts as “serious” is frequently contested and is often the difference between a misdemeanor and a strike.

Battery on a Peace Officer — Penal Code § 243(b) and (c)

Enhanced penalties apply where the alleged victim is a police officer, firefighter, paramedic, or other protected worker performing their duties.

Domestic Battery — Penal Code § 243(e)(1)

Battery against a spouse, cohabitant, dating partner, or co-parent. It carries a different penalty structure and a separate set of consequences. → Domestic Violence

Criminal Threats — Penal Code § 422

Threatening someone with death or great bodily injury, where the threat is specific enough and immediate enough to place them in sustained fear. It’s a wobbler and, charged as a felony, it’s a strike offense. Criminal threats are frequently filed alongside assault charges.

Note: California calls this offense “criminal threats.” Some other states use “terroristic threats” — the California statute is Penal Code § 422.

What the Prosecution Has to Prove

For assault under Penal Code § 240, the prosecution must prove beyond a reasonable doubt that:

1. You did something that by its nature would directly and probably result in the application of force to someone;
2. You acted willfully;
3. You were aware of facts that would lead a reasonable person to realize the act would probably result in force being applied; and
4. You had the present ability to apply force.

For battery under Penal Code § 242:

1. You touched someone;
2. You did so willfully; and
3. The touching was harmful or offensive.

Two things matter here. Present ability is a real limit on assault — a threat made from too far away, or without the means to carry it out, may not qualify. And in both offenses, the prosecution must prove you were not acting in self-defense, which is where most of these cases are genuinely fought.

Penalties for Assault and Battery in California

⚠️ VERIFY BEFORE PUBLISHING — all figures require Polina’s sign-off. See Open Items.

Simple assault (§ 240) and simple battery (§ 242) are misdemeanors carrying county jail exposure, fines, and probation.

Assault with a deadly weapon (§ 245(a)(1)), assault likely to produce GBI (§ 245(a)(4)), and battery with serious bodily injury (§ 243(d)) are wobblers. As felonies they carry state prison exposure that rises with injury severity, weapon use, and prior record.

Great bodily injury enhancements under Penal Code § 12022.7 can add consecutive time on top of the base sentence.

Consequences Beyond Sentencing

• Strike consequences. Felony ADW and felony criminal threats can qualify as strikes, doubling exposure on any future felony.
• Firearm rights. Felony convictions carry a lifetime prohibition; some misdemeanor convictions carry a 10-year ban.
• Immigration. Assault and battery offenses can be treated as crimes involving moral turpitude, with serious consequences for non-citizens.
• Employment and licensing. Violent offense convictions are weighed heavily, particularly in healthcare, education, and security.
• Protective orders, restitution, and mandatory anger management are common conditions.
• Civil liability. The alleged victim can sue separately, and a criminal conviction makes that case substantially easier for them.

Defenses to Assault and Battery Charges

Self-Defense and Defense of Others

This is the defense that decides most of these cases. California permits reasonable force to protect yourself or someone else from imminent harm. Once self-defense is raised, the prosecution bears the burden of disproving it beyond a reasonable doubt.

What matters is what a reasonable person would have believed in that moment — not what turned out to be true afterward. And the person who called 911 first is not necessarily the person who was defending themselves.

Lack of Intent

Both offenses require willful conduct. Accidental contact, contact during a fall or a crowded encounter, and reflexive movements don’t satisfy that element.

No Present Ability

Assault requires the present ability to apply force. Threats made from a distance, through a barrier, or without any means to follow through may fall outside the statute.

The Contact Wasn’t Harmful or Offensive

Battery requires offensive touching. Incidental contact, ordinary jostling, and contact the other person invited or consented to may not qualify.

Mistaken Identity

Fights involving multiple people, poor lighting, or intoxicated witnesses produce unreliable identifications with real frequency.

False or Exaggerated Allegations

Assault allegations surface in custody disputes, neighbor conflicts, landlord-tenant disputes, and workplace grievances, where an accusation carries leverage. Timing and motive are investigable.

Insufficient Evidence

Many of these cases come down to two conflicting accounts with no video, no injuries, and no independent witnesses.

Related Charges

• Domestic Violence — Penal Code § 273.5 and § 243(e)(1)
• Criminal Threats — Penal Code § 422
• Gun Charges — where a firearm was involved or alleged
• Gang Crimes — gang enhancements are frequently attached to violent charges
• Elder Abuse — Penal Code § 368
• Restraining Orders — often issued alongside these charges
• Expungements — clearing a prior assault or battery conviction

Why a Former Prosecutor Matters in an Assault Case

Assault and battery cases get filed fast, usually on a police report written within hours of a chaotic scene, before anyone has interviewed the witnesses properly or examined whether the person arrested was actually the aggressor.

Polina Logrue reviewed and filed those cases at the Orange County District Attorney’s Office. She knows what a report looks like when the officer made a quick call, which self-defense claims prosecutors take seriously, and what it takes to get a felony § 245 charge reduced to a misdemeanor — or dropped.

She also knows how the office weighs an alleged victim who stops cooperating, and what it does and doesn’t change.

Charged With Assault or Battery? Do This First

1. Photograph your own injuries immediately. Self-defense claims are frequently proven or lost on this alone, and injuries fade within days.
2. Write down what happened while it’s fresh — who was there, who made contact first, what was said, and where any cameras were.
3. Identify witnesses now. People at a bar, a party, or a parking lot scatter and become unreachable within a week.
4. Preserve any video. Security footage is routinely overwritten in 30 days or less. An attorney can send a preservation letter.
5. Don’t contact the alleged victim — especially if a protective order has issued.
6. Don’t explain your side to police. Even “he swung first” gets recorded, summarized, and used in ways you didn’t intend.
