A battery assembly comprises a battery housing that defines an opening and includes one of a first engagement member and a second engagement member. A feedthrough member is disposed with the opening and extends from the battery housing. A connector includes at least one electrical terminal electrically communicating with the feedthrough member and includes one of a first engagement member and a second engagement member. The engagement members are disposable in a mating configuration to assemble the battery housing and the connector. Implantable medical devices, systems and methods are disclosed.

In lithium iodine electrochemical cells, control of polyvinylpyridine film thickness and/or polyvinylpyridine film surface area coverage and/or control of the quantity thereof on or with respect to the lithium anode operative surface directly affects cell voltage characteristics during discharge, allowing the tailoring of the voltage characteristics near cell end-of-life (EOL) in a useful way.
