    This is a list of spacecraft powered by non-rechargeable batteries.While most spacecraft are powered by longer-lasting power sources such as solar cells or radioisotope thermoelectric generators, which can provide power for years to decades, some have been powered by primary (non-rechargeable) electrochemical cells, which provide runtimes of minutes to months.

    Venera 4V-2 (Russian: Венера 4В-2) was a series of two identical spacecraft sent to Venus by the Soviet Union, consisting of Venera 15 and Venera 16. [1] Both uncrewed orbiters were to map the surface of Venus using high resolution imaging systems. The spacecraft were identical and based on modifications to the earlier Venera space probes.

    On 5 March 1979, Soviet spacecraft Venera 11 and Venera 12, then in heliocentric orbit, were hit by a blast of gamma radiation at approximately 10:51 EST.This contact raised the radiation readings on both the probes from a normal 100 counts per second to over 200,000 counts a second in only a fraction of a millisecond.

    en.wikipedia.org/wiki/Venera_11

    The SIGNE 2 detectors were simultaneously flown on Venera 12 and Prognoz 7 to allow triangulation of gamma ray sources. Before and after Venus flyby, Venera 11 and Venera 12 yielded detailed time-profiles for 143 gamma-ray bursts, resulting in the first ever catalog of such events. The last gamma-ray burst reported by Venera 11 occurred on ...
