Abstract:
1. A method for soldering a junction defined by a portion of a battery strap in physical contact with a terminal of a dry cell for electrically and physically connecting said battery strap to said terminal for fabricating a dry cell storage battery including the steps of: a) determining the resistivity to current flow of the materials defining said junction to be soldered; b) determining a value of a first voltage which when applied across said junction, having said determined resistivity, will generate a heat within said junction, sufficient to melt a solid solder placed within said junction into a liquid state solder; c) generating a second voltage having said value of said first voltage; d) applying said second voltage across said junction for generating heat within said junction for soldering said portion of said battery strap to said terminal; and e) limiting a duration of application of said second voltage using an ON/OFF timer element in a circuit associated with application of said second voltage.
