A pack of ordinary, commercially-available batteries is provided with a common electrolyte-filled reservoir coupled to each battery by a small tube. The reservoir includes a compliant diaphragm which, when exposed to deep-sea pressure, applies the pressure to the reservoir electrolyte to force it into the battery. Forceful filling of the cells equalizes their internal and external pressures. Electrical discharge currents are reduced to a minimum by making the tubes as small as and as long as possible. Author
