Over time batteries will die and the badge system will become useless unless everyone gets new badges once a semester.
Or, you know, change the battery. Which would take seconds per unit if you’re doing a whole bunch of them.

Which would lead to a gap in protection. It’s also not clear if the battery is easily serviced

For a matter of seconds as someone chucks a new battery in the badge, sure.
There’s not a lot of information about how the system actually works, but schools are typically quite budget conscious organisations, so I can’t imagine just throwing out the badge when the battery dies would go down well.
