The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of making a device to indicate an amount of available charge in at least one battery cell comprising the steps of:
providing a battery with at least one battery cell, a ground signal, and a clock signal,
coupling a state-of-charge indicator to said at least one battery cell within said battery, and
configuring said state-of-charge indicator to operate in a hibernation mode by coupling a detachable physical key to said ground signal and said clock signal.
2. The method of claim 1, wherein configuring said state-of-charge indicator to operate in a hibernation mode comprises the step of:
configuring said state-of-charge indicator to draw a minimum amount of charge from said at least one battery cell by coupling a detachable physical key to said ground signal and said clock signal.
3. The method of claim 1, further comprising the step of:
