  • Arrangement of battery poles of an electric energy accumulator
    Patent number: 8758932
    Abstract: A power accumulator (1) has at least three contacts (5 and 7), the contacts (5 and 7) being partially positive contacts (5) and partially negative contacts (7). The contacts (5 and 7) are arranged symmetrically with respect to the external shape of the power accumulator (1), especially with respect to a longitudinal center plane (3) thereof. In this way, the power accumulator (1) can be inserted in any alignment into a device (consumer or charger) without the danger that the power accumulator (1) will be connected with incorrect polarity.
