>When the AMSAT-OSCAR 7 (AO-7) amateur radio satellite was launched in 1974, its expected lifespan was about five years. The plucky little satellite made it to 1981 when a battery failure caused it to be written off as dead. Then, in 2002 it came back to life. The prevailing theory being that one of the cells in the satellites NiCd battery pack, in an extremely rare event, shorted open thus allowing the satellite to run (intermittently) off its solar panels.

I used to have an old Popular Electronics magazine from the late 60s or early 70s that had an article on the original OSCAR ham satellite. It was cool to see that sort of ham tech going on that early. The NiCd battery pack they picture in the Hackaday article is really nostalgic for me because the PE magazine I had contained ads for a few places that were selling those same NiCd satellite battery cells. IIRC they were 2V cells at about 4 Ah and sold for around $2 a cell. I really wanted some of those, but I only discovered them about 20 years later and they were probably all dead or out of stock everywhere. They were really neat though.
