Start your Batteries & Emergency Power recap

This quiz is designed to reinforce Module 31 battery and emergency-power knowledge, improve recall, and identify the areas that need revision before mock orals or a live MCA oral examination.

Explain the SOLAS Chapter II-1 emergency-source route from main failure to emergency generator start, emergency switchboard supply and essential services.
Understand emergency generator location, independence, starting arrangements, endurance, fuel flash point, heel/list and trim requirements.
Compare lead-acid, alkaline and lithium-ion batteries using cell voltage, capacity, maintenance and safety considerations.
Explain lead-acid discharge/charge chemistry, specific gravity, hydrometer checks and why voltage alone does not prove capacity.
Diagnose emergency-start and battery faults using charger condition, terminals, electrolyte, load testing and alternate starting methods.
Explain battery-room hydrogen hazards, ventilation, Ex markings, intrinsically safe equipment and zener-diode barrier operation.
