Patent ID: 7688596

Claim:
An electrical energy storage device, comprising: a) a casing; b) an anode and a cathode with an intermediate separator preventing direct physical contact between them to form an electrode assembly housed inside the casing, wherein a terminal pin is electrically connected to one of the anode and the cathode and is of an opposite polarity than the casing electrically connected to the other of the anode and the cathode; c) a protective housing comprising a sidewall having a height extending from a lower end supported on the casing to an upper end; d) a circuit board electrically connected to the electrode assembly and surrounded by the sidewall of the protective housing; e) at least one lead having a length extending between a proximal end electrically connected to the circuit board and a spaced apart distal end; f) a cut-out extending from the upper end of the protective housing sidewall part way through its height toward the lower end thereof; and g) at least one retaining wall extending upwardly from a lower surface of the cut-out to thereby provide at least one gap between the retaining wall and the cut-out, the gap being of a width that is less than that of the lead so that the lead is movable into the gap to be captured therein with the distal lead end extending outwardly from the protective housing.
