Car battery with casing and at least two electric terminals, i.e. battery cathode and anode, on casing outside, which are in form of two adjacent sockets for matching plug

摘要

Battery casing (1) comprises at least two electric terminal elements on outside, as battery cathode and anode, forming two adjacent sockets (2,3) for matching plug (5), preferably single plug with two adjacent plug pins (7,8).Both sockets may have different cross-sectional shapes, permitting insertion of complementary plug pins in one or both sockets. Typically at least one plug connector box (4) with both sockets is located at one wall of battery casing.
