46 CFR §111.105-41

§ 111.105-41 -41 Battery rooms. Each electrical installation in a battery room must meet 46 CFR subpart 111.15 and IEEE 45.1 (incorporated by reference; see 46 CFR 110.10-1). [USCG-2003-16630, 73 FR 65201, Oct. 31, 2008; USCG-2020-0075, 88 FR 16367, Mar. 16, 2023]

46 CFR §111.15-1

§ 111.15-1 -1 General. Each battery must meet the requirements of this subpart. [CGD 94-108, 61 FR 28277, June 4, 1996]

46 CFR §111.15-2

§ 111.15-2 -2 Battery construction. (a) A battery cell, when inclined at 40 degrees from the vertical, must not spill electrolyte. (b) Each fully charged lead-acid battery must have a specific gravity that meets Section 11 of IEEE 45.1-2017 (incorporated by reference; see § 110.10-1 of this subchapter). (c) Batteries must not evolve hydrogen at a rate exceeding that of a similar size lead-acid battery under similar charging condition. (d) Batteries must be constructed to take into account the environmental conditions of a marine installation, including temperature, vibration, and shock.

46 CFR §111.15-25

§ 111.15-25 -25 Overload and reverse current protection. (a) An overload protective device must be in each battery conductor, except conductors of engine cranking batteries and batteries with a nominal potential of 6 volts or less. For large storage battery installations, the overcurrent protective devices must be next to, but outside of, the battery room. (b) Except when a converter is used, the charging equipment for all batteries with a nominal voltage more than 20 percent of line voltage must protect automatically against reversal of current. [CGD 74-125A, 47 FR 15236, Apr. 8, 1982, as amended by USCG-2020-0075, 88 FR 16361, Mar. 16, 2023]

46 CFR §111.15-3

§ 111.15-3 -3 Battery categories. (a) A battery installation is classified as one of three types, based upon power output of the battery charger, as follows: (1)A large battery installation is one connected to a battery charger that has an output of more than 2 kW computed from the highest possible charging current and the rated voltage of the battery installation. (2)A moderate battery installation is one connected to a battery charger that has an output of between 0.2 kW and 2 kW computed from the highest possible charging current and the rated voltage of the battery installation. (3)A small battery installation is one connected to a battery charger that has an output of less than 0.2 kW computed from the highest possible charging current and the rated voltage of the battery installa…

46 CFR §111.15-30

§ 111.15-30 -30 Battery chargers. Each battery charger enclosure must meet § 111.01-9. Additionally, each charger must be suitable for the size and type of battery installation that it serves. Chargers incorporating grounded autotransformers must not be used. Except for converters, chargers with a voltage exceeding 20 percent of the line voltage must be provided with automatic protection against reversal of current.
