Sharopolis | Cartridge Battery Life? @Sharopolis | Uploaded May 2023 | Updated October 2024, 1 day ago.
Lots of old school game cartridges have save batteries in them, including some of the biggest and best known games of all time. From The Legend of Zelda to the Pokémon series, but how long do they last? How long before they run out and your save disappears? I did some measurements, ran some numbers and did some investigating to find out.
