Battery under Florida Statute § 784.03 means intentionally touching or striking another person against their will, or causing bodily harm. A first conviction is a first-degree misdemeanor (up to one year jail), but a second battery conviction is a third-degree felony. When the alleged victim is a family or household member, a domestic violence designation attaches with enhanced consequences like a mandatory no-contact order and a 10-day jail minimum on conviction. Defenses include self-defense, de minimis contact, mutual combat, and witness credibility attacks.
