Hi Henry,

Another point of toxicity. Because the nuclear "Boomers" contained a
closed loop environmental system, ALL such batteries were banned from
the boat irrespective of their need in ANY equipment. We had to make
do with substitutes and jury rig our own holders or means to provide a
voltage for key equipment that would work fine on surface craft.
