Spintronic Battery (6 V)

This spintronic battery powers spintronic circuits. It provides a constant spin voltage of 6 V when it is charged by pulling the string back.

This 6 spin volt battery has a maximum capacity of 0.3 mAh. A pull string charges the battery, and a constant torque spring provides a nearly constant spin voltage all the way until its charge is fully depleted. In the event of a short circuit, a built-in circuit breaker stops it immediately. The breaker is reset by charging the battery once more.
