Abstract: Multiple unique keyed fluid connectors that are not cross-connectable with each other are described. Each keyed fluid connector comprises a first body including a first mating surface and having a first fluid fitting disposed in a first port in the first mating surface; a second body including a second mating surface opposable to the first mating surface and having a second fluid fitting disposed in a second port in the second mating surface, the second fluid fitting connectable to the first fluid fitting; and a keying feature comprising at least a first pin extending from one of the first and second bodies and disposable in a first hole in the other of the first and second bodies. The connectors are particularly useful in providing a robust system for selecting a particular electrolyte from among several containers of different electrolytes, and dispensing it into an implantable power device.
