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).
This can be pretty confusing at times, happened to me as well. Its because the anodes and cathodes change signs under different conditions. In a discharging battery (Galvanic cell), the anode is the negative terminal, and cathode is positive. In a recharging battery (Electrolytic cell), the opposite happens, anode is positive and cathode is negative.
