A secondary cell featuring transient rise in temp. once charged to saturation, to be coupled and thereby forming a composite structure with a charging assembly by mutual engagement of conductive contacts provided on either part, the force of union generated by the coupling will compress a thermosetting prestressed means which is a spring or otherwise prestressed element while the coupling brings the contacts into conduction by which the charging is initiated, the momentum prestressed thereby will be released once charging in the secondary cell reaches its saturation, and that followed by cutoff of the charging current to the secondary cell.
