I also like those powerful batteries that can get the temperature in the spacecraft down from 250 degrees to a comfortable 72 . Meanwhile , here on planet earth we don’t have batteries for an RV that can get an air conditioner down from 95 to 72

They used alpha emitting nuclear batteries with plutonium238 and a bunch of thermocouples. Curiosity on Mars also uses nuclear batteries.

The SNAP-27 power supply weighed about 20 kilograms, was 46 cm long and 40.6 cm in diameter. It consisted of a central fuel capsule surrounded by concentric rings of thermocouples. Outside of the thermocouples was a set of fins to provide for heat rejection from the cold side of the thermocouple.
Each of the SNAP devices produced approximately 75 W of electrical power at 30 VDC. The energy source for each device was a rod of plutonium-238 weighing approximately 2.5 kilograms and providing a thermal power of approximately 1250 W.
