Forget that, what powers them? Something that can be read with a close by scanner makes some since since I figure you could induce a current in one, but the kind you sometimes see in movies that constantly sends out a signal that some satellite can clearly track anywhere in the world, and do so for days, weeks, months or longer, would need one heck of a battery I’d imagine? And in a very small space too

Pacemakers have batteries and modern ones broadcast a lot of telemetry, and last up to a decade. Not sure how much more power would be needed to broadcast to a satellite or cell tower though.
Bring back RTGs! They’ve already proven their use in pacemakers.
