USCG Exam PracticeBatteries and storage systems
Under 46 CFR §111.15-3(b), a sealed battery that generates less hydrogen than an equivalent lead-acid battery under normal charging and discharging conditions may be treated in what manner with respect to its installation category?
- A. It must be upgraded to the next higher installation category regardless of hydrogen output
- ✓ Its battery category may be reduced to an equivalent category of lead-acid batteriesCorrect
- C. It is exempt from all battery installation requirements in subpart 111.15
- D. It must be classified as a large installation to account for unknown hydrogen generation
Why B is correct
46 CFR §111.15-3(b) provides that batteries generating less hydrogen than an equivalent lead-acid battery (e.g., sealed batteries) may have their category reduced to the equivalent lead-acid category. This allows less restrictive installation requirements based on reduced hazard, not exemption from all requirements.
