USCG Exam PracticeBatteries and storage systems
Under 46 CFR §111.15-3(b), under what condition may a battery installation be reclassified to a lower category than its charger output would otherwise require?
- A. When the battery is a lead-acid type with a nominal voltage below 12 volts
- ✓ When the battery generates less hydrogen under normal charging and discharging conditions than an equivalent category of lead-acid batteriesCorrect
- C. When the battery charger is equipped with automatic reverse current protection
- D. When the battery installation is located in a dedicated battery room with Class I, Division 1 electrical equipment
Why B is correct
46 CFR §111.15-3(b) allows a battery installation to be reclassified to a lower category if it generates less hydrogen than an equivalent lead-acid battery under normal charging and discharging conditions, such as sealed batteries. The other options describe real regulatory requirements but are not the basis for category reduction.
