The Exide submarine battery cell is
located in the waiting area for the USS Cobia
tours. Between visits, the museum relocated the cell from against an interior
wall to against an exterior glass wall.
It's hard to keep in mind that this is not a "battery", but merely one of 126
cells which makes up one of the sub's two batteries!
Additional information about the batteries and their cells can be found in Chapter 5 of
Electrical Installations manual at The Fleet Type Submarine
