 Silver Zinc Technology

Since the beginning of the Space Age, EaglePicher Silver Zinc batteries have been trusted to power historical NASA launches including: Mercury, Gemini, Apollo, and Skylab. Today, with more than 50 years of Silver Zinc battery production heritage, and more than 200 battery designs, we continue to produce reliable, complex systems for the missile, aerospace, and maritime industries.

Development of the automatic and remote activated silver-zinc batteries at EaglePicher was initiated in the early 1950’s. The early systems developed were simple single section batteries with one voltage output. By maintaining flexible engineering to ensure custom design, development, qualification, production and delivery, we are able to meet the requirements of each unique program.
