1 . Charging Device with stress stored by charging that is initiated by externally applied force and the stored stress being eventually released by heat due to charging saturation, comprising a secondary cell which is characterized by a transient rise in temp. once charged to its saturation, and which can be one of a nickel/cadmium, nickel/hydrogen, nickel/zinc, nickel/iron base battery to be matched in a charging assembly therefor and both executed per specific design, with conductive contacts provided on both parts for the transmission of electric power, force of union prevailing when both are combined together will suffice to compress spring or other prestress element to be released of stress previously stored in the wake of ambient heat, charging is made when contacts on both parts are enabled one on one, forming a coupled pair, and once the charging reaches its saturation, as confirmed by a testing device provided therefor, addressed to the secondary cell set, by the working of a mechanical thermosetting prestress device the stress previously stored will be released forthwith, and that sufficient to unmake the contact-to-contact coupling theretofore established between the secondary cell set and the charging assembly, including alternatively unmaking of contacts on the secondary cell set alone, or those on or within the charging assembly alone, and charging current to the secondary cell is cut off at the same time. 
 The cell charging saturation testing device as mentioned in the foregoing can be any of a variety of temperature sensors with the charging assembly and the secondary cell set being combined vertically upwards and uncoupled downwards, or alternatively combined downwardly and uncoupled upwardly in the vertical orientation; or still combined and uncoupled horizontally; or still combined and uncoupled in otherwise angular setting relative to each other, whereof the prestressed thermosetting means comprises: 
 (1) Thermosetting flip-flop binary metal spring sheets;  
 (2) Thermosetting flip-flop binary metal retainer and spring;  
 (3) Having resilient positioning mortise joint and dovetail coupling provided on both the charging assembly and the secondary battery cell set to localize charging operation, and that complemented with thermo-setting memory alloy or binary metal structure to be deformed by heat expansion once charging that is taking place in the secondary cell set has reached its saturation, when that occurs conductive contacts binding the secondary cell set with the charging assembly are brought apart, including alternatively unmaking of contacts solely in the secondary cell set, or in the charging assembly, or still inside the charging assembly, and power supply is blocked forthwith;  
 (4) Having conductive contacts on the charging assembly and conductive contacts on the secondary cell set retained resiliently in position with respect to each other, forming thereby a pair, and having thermosetting memory alloy or binary metal sheets or annular spring units arranged down the secondary cell set once the cell set is loaded in place, so that a secured attachment is made, so that thermal deformation which occurs when the secondary cell set is charged to saturation will bring the secondary cell set and the charging assembly apart from each other by disengagement of the pair of contacts, including alternatively unmaking of contacts solely in the secondary cell set, or in the charging assembly, or still inside the charging assembly, and power supply is blocked forthwith;  
 (5) Having thermosetting memory alloy or binary metal processed into conductive contacts for the charging assembly, meant, in addition to getting coupled to conductive contacts on the secondary cell set, but also for holding the secondary cell set in position, such conductive contacts for the charging assembly, on being heated by saturation of charging of the secondary cell set, will get deformed to release hold of the secondary cell set which will then fall straight off the conductive contact and power supply is blocked forthwith;  
 (6) Having the contacts for the charging assembly materialized by heat transformation of the memory alloy or binary metal, together with another set of contacts likewise functioning as a prestress spring coupled to the conductive contacts on the secondary cell set, and to hold in place the same secondary cell set at the same time, so that when conductive contacts on the charging assembly, on receiving heat from the effect of saturation of charging of the secondary cell set, becomes deformed to release hold of the secondary cell set, the interactive coupling of contacts between the secondary cell set and the charging assembly are defeated by the prestressed conductive contact functioning like a prestressed spring, or alternatively the defeat be with respect to the secondary cell set only, or to the charging assembly only, or to internal contacts of the charging assembly only, power supply is blocked forthwith, it is to be noted that both sets of conductive contacts of the charging assembly may be those featuring thermosetting or prestressed spring traits;  
   Structured accordingly, when the secondary cell is loaded into the charging assembly, force applied externally will compel the cell to bring contacts on both the charging assembly and the cell into conductive coupling whereupon charging to the cell begins, and that in turn brings the Battery Charging Saturation Testing Device to a testing state, once the cell is charged to saturation, then both the Charging Saturation Testing Device and the interfacing matched thereby will respond to reset both the charging assembly and the cell set to a released, that is, open state, and power supply to the secondary cell set is blocked forthwith.

 (1) Those provided with auxiliary heater which will produce heat when receiving electric power incurred by saturation of charging in the secondary cell set, the auxiliary heater being of a flip-flop binary metal prestressed design or of a thermosetting binary metal design, heat thus produced will unmake straight contact-to-contact coupling between the secondary cell set and the charging assembly, including alternatively unmaking of contacts on the secondary cell set only or of or within the charging assembly only, so that power supply is cut off forthwith; or    (2) Those provided with flip-flop binary metal prestressed spring or memory alloy or binary metal base thermosetting structure which, when receiving heat that is produced as charging in the secondary cell reaches its saturation, will unmake the contact-to-contact coupling between the secondary cell set and the charging assembly, including alternatively, unmaking of contacts on the secondary cell only, or unmaking of contacts on or within the charging assembly, such that power supply is cut off forthwith; or    (3) Those provided with a resilient positioning means comprising a memory alloy or binary metal base thermosetting structure which, together with a compression spring seated way between the charging assembly and the secondary cell set, will, by releasing the spring due to triggering effect when the thermosetting resets itself in the wake of effectual heat, unmake the secondary cell and power supply is cut off forthwith; or    (4) Those provided with a resilient positioning means which is bound by conductive contacts and made from a memory alloy or binary metal base thermosetting structure which, when receiving an effectual heat, will trigger off a prestressed spring that is seated way between the charging assembly and the secondary cell set, so that the secondary charging cell is disengaged and the power supply to which the charging is due is cut off forthwith; or    (5) Those on which the memory alloy or binary metal base thermosetting structure is executed to be a charging assembly with conductive contacts thereon furnished to accommodate coupling with counterpart contacts on the secondary cell set, and meantime to hold the same secondary cell set in place, said contacts on the charging assembly, when affected by the heat released from the secondary cell as it is charged to saturation, will get deformed, thereby releasing the secondary cell set which will then drop off said contacts, and charging operation is cut off forthwith;    (6) Those structured such that by the contacts furnished on the memory alloy or binary metal base thermosetting charging assembly, as well as another set of contacts featuring a prestressed spring function, extended with an insulated stretch arm, when a secondary cell set is laden, coupling will be made with respect to contacts on the secondary cell set, which, together with the secondary cell set being clamped in the meantime, will start charging with respect to the secondary cell set, whereupon the engaging head on the tail end of the insulated stretch arm is matched with counterpart engaging receptacle on the tail end of memory alloy base, thermosetting contact, in a prestressed engagement, when charging in the secondary cell set reaches its saturation to release heat, contact on the charging assembly, on receiving said heat, will get deformed, resulting in dissociation of the insulated stretch arm on the contact that is retained by prestress, apart from the engaging receptacle, such that the secondary cell set is released, then the prestress stored in the insulated stretch arm on the contact enabled by said prestress will bring contact-to-contact coupling thus far established between the secondary cell set and the charging assembly apart, including alternatively disengagement of contacts on the secondary cell set only or contacts on or within the charging assembly only, and power supply for charging purposes cut off forthwith. As an alternative structure the two sets of contacts on the charging assembly may comprise entirely prestressed thermosetting, spring-functioning contacts with extension of an insulated stretch arm; or    (7) Those employing altogether two or more of any testing devices specified in item  1  through item  6  disclosed hereinbefore; or
