Abstract:

Tests were conducted using lead-acid batteries as a power supply on the bathyscaph TRIESTE. Methods were developed for encapsulating batteries, relaying power, insulating batteries, and transmitting water pressure to prevent casings from collapsing. Lead-acid storage batteries were found to provide an effective and practical power source under pressures up to 16,000 psi and temperatures down to 35F. They are cheaper than silver-zinc cells and may be mounted externally to save cabin space. Report recommends them on TRIESTE and recommends extending investigations to include other types of wet batteries for similar uses. Charts and illustrations provide information about battery performance, installation, and testing procedure. Author
