Since 1986 Saturn PJSC has been developing and manufacturing storage batteries of Nickel-Hydrogen electrochemical system for spacecraft. The first Nickel-Hydrogen battery was installed on the communication satellite "Ekran-M" in 1988. Since then, the scope of storage batteries application is expanding rapidly. To date (2017), the total flight time is more than 500 million cell-hours.
According to a specially developed manufacturing technique, product pretesting is carried out in a wide range of tests: from electrical and climatic cycles to shock and vibration tests.
