I just tried booting up my 3ds for the first time in 2 years and the battery was dead. I then booted up my original DS which I haven’t turned on in like 10 years and longer than that since it was last charged. It turned on with a green light still! Why does the battery hold its charge when just about all other electronics with built in batteries die without over long periods of time?

I’ve wondered this same thing. My DS never loses its charge when just sitting unused but every other electronic device I own does.
The 3DS is much newer and has some systems that never truly turn off. It has certain wireless capabilities that are meant to continue working even when the device is “off”, which provide an occasional small drain on battery life. The original DS had no systems like that, so off likely actually means off on the originals.
The stranger thing is that most lithium batteries would be dead, even sitting unplugged and completely idle, after 10+ years. If yours is still powering on, that’s pretty surprising if you haven’t charged it in that long.
