| Mar 9, 2023 at 19:20 | comment | added | Theodore | @Lundin I said nothing about burying anything at all. I never indicated a quantity greater than one, much less about "digging down batteries left and right." I had something like this in mind. | |

| Mar 9, 2023 at 16:44 | comment | added | LuC | As commented below, be careful in choosing all the components, esp. capacitors. No electrolyte-based ones, possibly no ceramic ones (moisture sensitive). Provide a thick conformal coating to everything. Maybe you can be luckier with temperature: if the device is buried somewhere it will reasonably stay far from the outside high and low | |
| Mar 9, 2023 at 15:55 | comment | added | Lundin | Please don't dig down batteries or other forms of electronic waste in the wilderness. 100 years from now on we'll likely be regarded as a bunch of clueless idealists who aimlessly damage the environment. Around 100 years back, this guy en.wikipedia.org/wiki/Thomas_Midgley_Jr was regarded as a genius. Among his inventions were leaded gasoline and freon for refrigerators. Today we can conclude that he didn't have a clue of the consequences of his inventions. We can only guess what people 100 years from now on will think of that guy who was digging down batteries left and right. | |

| Mar 8, 2023 at 18:08 | comment | added | Matt S | Does it need to be a chemical battery? Can you pack a hand or foot-powered generator with assembly instructions? Coils, magnets, and mechanical parts, stored properly, are likely to last as long as anything else you can store in there. | |

| Mar 8, 2023 at 17:34 | comment | added | Justme | Does it have to be a battery in traditional sense? How about solar cells, RTG/nuclear, thermal generator, hydrogen cell, watermill, or wind generator? | |

| Mar 8, 2023 at 16:33 | comment | added | Hearth | Wet cell chemistries stored without water and well-sealed can last a long time; the battery doesn't really start being a battery until you add water to it. I don't know about 100 years, though. | |
