Not according to the Pennsylvania Crimes Code.

Offensive physical contact is assault.

Simple assault, 18 Pa.C.S. 2701, includes "attempts to cause or intentionally, knowingly or recklessly causes bodily injury to another." "Aggravated assault" in Pennsylvania, 18 Pa.C.S. 2702, basically involves serious bodily harm or an attempt to do so.

There is no separate crime of battery in Pennsylvania. "Battery" is subsumed in the assault statutes. Other states may have different laws on assault and some do have a distinct crime of "battery."

"Battery" traditionally means an offensive physical contact, and is basically a civil tort concept. If I punch you in the face in Pennsylvania, I will face a criminal assault charge, and you can file a civil lawsuit for money damages, based on battery.
