Under Oklahoma law, battery is "any willful and unlawful use of force or violence upon the person of another." The difference between battery and assault is that assault is an attempted battery or a threat of battery, whereas battery is the completed act.
If you have an alibi, you should be fine. I would suggest that when and if charges are filed, you get a lawyer as soon as possible to protect your rights. If you can't afford one, apply for the services of the public defender.
Hope this helps.
