(DE19611776-A1)      A four-pole battery has one battery with a plus pole for the starter motor and a second one with a plus pole for the accessories. The starter battery has high current plates and the auxiliary one has low-discharge plates. The two battery sections have different construction but are side by side in a common housing, each with its own minus pole.    The volumes of the two sections are different; the volume of the starter battery preferably being 1.86 or 1.22 times that of the auxiliary one. The housing is a one-piece casting. Neither battery has a common minus pole. The two sections can be series connected to give a higher voltage.    ADVANTAGE -   One section for starting and one section for other electrical loads.    (FR2731845-A1)      A four-pole battery for vehicles includes a cranking battery (CRA) (23) with a positive pole for connection to a starter motor, and an auxiliary (AUX) (22) battery with a positive pole for connection to the auxiliary loads.    The CRA battery has high current plates, the AUX battery having deep cycle plates, both batteries being of different construction and housed in a case which is a monobloc moulding, with side-by-side compartments.The CRA battery has a positive and a negative pole and the AUX battery has a positive and negative pole,    but neither battery has a common negative.    USE/ADVANTAGE -   For automotive and marine applications, such as starting motor vehicles and boats. Easy to mfr. and easy to connect into vehicle for controlling electronic circuitry.
