Other Lead-Acid Batteries. Other lead acid batteries used by the Coast Guard are EI Series (EI-5,
7, 9, 11, 13, 15, and 17) and FHGS Series (FHGS-17, 21, 25) manufactured by Exide; Absolyte-II,
Series 75 and 85 manufactured by GNB; and DH-5-1 manufactured by Willard. These batteries are
large in size and are used in limited numbers in lighthouses.
C.
BATTERY CLASSIFICATION
Primary batteries are designated S or B, for their use at Shore (fixed) aids (S) or on Buoys (B). The
next two digits of the classification represent the capacity of the battery in 100 ampere-hours. The
last letter in the battery classification is A for liquid, or D for dry electrolyte. The number of cells
in a battery is indicated by a digit in front of the first letter. A buoy power unit is a set of two
and/or three battery cells connected in series, and/or parallel to obtain 12 or more volts, and
capacities of 1000, 2000, 3000, 6000, etc. ampere-hours. Photographs and illustrations of various
types of batteries are provided in Appendix A.
