If we go for the diagramatic representation then battery positive is represented by the long terminal and battery negative is represented by the short terminal then the direction of the current is given by an arrow from positive terminal to negative terminal (Therotically electrons flow from negative to positive but we represent current flow from positive to negative. This is the sign convention )
