    en.wikipedia.org/wiki/Batteries_in_space

    Batteries are used on spacecraft as a means of power storage. Primary batteries contain all their usable energy when assembled and can only be discharged. Secondary batteries can be recharged from some other energy source, such as solar panels or radioisotope-based power (), and can deliver power during periods when the space vehicle is out of direct sunlight.

    Its orbital configuration had a diameter of 60 in (1.5 m) and a length of 248 in (6.3 m), and provided 19,500 Wh of electrical power from batteries. [10] As of 2014, the Agena-D is the most-launched US upper stage. [11] A special production line was set up to turn out 40 Agena-D spacecraft per year.

    The original expected lifetime of the satellite before orbital decay was three years. [14] Mercury batteries powered the high-power transmitter for 31 days and the low-power transmitter for 105 days. Explorer 1 stopped transmission of data on 23 May 1958, [17] when its batteries died, but remained in orbit for more than 12 years. [18]
