A battery connector includes an insulation housing and conductive terminals. The insulation housing has slots, and the conductive terminals are held in the slots. Each conductive terminal includes an elastic connecting portion, a contact portion, and a fastening portion. The elastic connecting portion includes elastic arms parallel and substantially aligned along a transversal direction and connecting portions formed at two ends of each of the elastic arms. The contact portion includes a bendable contact portion extended forwardly from the elastic connecting portion and then folded and extended backwardly and an active contact arm formed at an end portion of the bendable contact portion. The fastening portion includes a bent portion extended backwardly from the elastic connecting portion and then folded and extended forwardly and a passive contact arm formed at an end portion of a bent portion and aligned with the active contact arm.
