Felony Battery Under California Penal Code 243(d): Serious Bodily Injury

In California, battery charges can either be misdemeanors or felonies, depending on the circumstances of the alleged crime. Typically, simple battery cases without aggravating factors are charged as misdemeanors. 

However, battery accusations can cross the line into felony territory under California Penal Code 243(d) if they result in serious bodily injury.

But what constitutes “serious bodily injury” under California law? And how do you know if a battery accusation against you will be considered a misdemeanor or a more serious felony? This article examines Penal Code 243(d) and the factors that influence whether battery charges rise to the level of felony convictions.

When Does Battery Become a Felony in California?

Most people are familiar with the general definition of battery – an intentional, unwanted touching of another person. However, not every battery charge is treated equally under California law. 

A simple battery, such as a shove during an argument, is typically charged as a misdemeanor. However certain factors can elevate this misdemeanor offense to a felony.

In our experience, the most common way battery becomes a felony is if it results in serious bodily injury to the victim. Under California Penal Code 242 PC, the legal definition of battery focuses on use of force or violence against another person. If said force or violence leads to grave impairment, such as broken bones, concussion, wounds requiring stitches, or disfigurement, the defendant may face felony aggravated battery charges.

Other actions that could justify felony battery charges include:

Use of a Deadly Weapon

If the defendant utilized a deadly weapon such as a knife, bat, brass knuckles, or firearm during the altercation, this elevates it to aggravated battery even if no injury occurred.

Prior Convictions

Those convicted of misdemeanor battery in California within 10 years of the current offense may now face felony charges and increased jail time if accused again.

Vulnerable Victim

If the victim is considered especially vulnerable, such as elderly, disabled, or a child, the defendant is more likely to have felony battery charges filed against them.

Penalties for Felony Battery Under California Law

In our experience defending clients facing accusations of aggravated battery, the penalties handed down depend greatly on the unique details of each case. However, California law does dictate certain sentencing guidelines that those found guilty of felony battery may face.

Prison Time

If convicted of felony battery in California resulting in serious bodily injury, penalties under Penal Code 243(d) can include up to 4 years in state prison. Even more prison time can be added if a deadly weapon was used during the battery. Those with prior convictions may serve up to 10 years.

In especially serious cases where traumatic injury or disfigurement occurred, or the victim suffers paralysis or other permanent disability, prison time can reach up to 10 years.


Fines for aggravated battery felonies often start at $10,000 in California. But again, the severity of injury, use of a weapon, or prior record can all impact the amount set by the court. Fines reaching $20,000 would not be unheard of in especially violent felony battery cases.


Many first-time felony offenders may have prison time suspended by the judge if probation is granted instead. While this avoids incarceration, probation comes with strict conditions. These can include mandatory counseling, drug/alcohol testing, community service hours, or restitution to the victim. Violating any terms of probation risks serving the full prison sentence behind bars.


As part of probation or a plea deal, the defendant will likely pay restitution funds to the victim injured during the battery. This compensates them for medical bills, property damage, lost income from missed work, therapy costs, and other hardships. Felony restitution can easily exceed $100,000 or more depending on the severity of injury.

Legal Defenses Against California Felony Battery Charges

When facing potential penalties this severe, building a strong legal defense is crucial. An experienced California criminal defense firm can evaluate the prosecution’s evidence and identify weaknesses that could lead to reduced or dismissed charges.

Here are some of the most effective legal defenses we frequently employ in defending clients against felony battery accusations:


If ample evidence suggests, our client faced a threat of violence or harm from the alleged victim, claiming self-defense can eliminate or reduce charges. The actions must match a reasonable use of force to protect oneself or loved ones.

Defense of Others

Similar to self-defense, if our client reacted violently to defend another person from harm, this may constitute legal justification for battery and dismissal of felony charges.

Mistaken Identity

In some cases, such as a bar fight with multiple participants, we can argue misidentification of the perpetrator if evidence suggests reasonable doubt. Eyewitness testimony has been proven highly unreliable.

No Serious Injury Occurred

If medical records, doctor testimony, or other evidence fails to conclusively prove serious or traumatic injury resulted from the alleged battery, charges may revert back to a misdemeanor.

The complexity of proving any felony battery accusation means a tough legal fight likely awaits if formally charged. Having the defense team at Kolacia Law Firm in your corner from the very start can make all the difference. Our firm has over 15 years of combined experience achieving charge dismissals, plea bargains to lesser charges, and even jury trial acquittals for clients facing battery allegations.
