Which Side of a Battery is Positive? A cell or battery is drawn with a long line and a shorter line. The long line is the positive side (plus is longer). The short line is the negative side (minus is shorter).

If the membrane moves out-toward you, the wire attached to the plus on the battery is plus-+.
