Storage batteries on "T-Boats" must be located __________.

Correct Answer: Option B — in a tray lined with suitable material that resists damage from the electrolyte

46 CFR 183.340 requires storage batteries to be located in a tray constructed of or lined with acid-resistant material. This prevents electrolyte leakage from damaging the vessel's structure or wiring. Proper containment is essential for preventing corrosion and maintaining the integrity of the vessel's electrical and structural systems.
