What is the approximate voltage per cell produced by the nickel-iron (Edison) battery?
Official USCG Answer & Rule Citation
Correct Answer: Option D — 1.37 volts
The nominal open-circuit voltage for a fully charged nickel-iron (Edison) storage battery cell is approximately 1.37 volts. This alkaline chemistry differs significantly from lead-acid cells. 46 CFR Subchapter J and IEEE 45 provide specific operational guidelines and charging safety requirements for diverse shipboard battery technologies.
