Why does the plasma battery take longer to respawn than the fusion coil, even when the respawn time is set to one second?
When the fusion coil explodes there is nothing left so it respawns almost exactly in 30 seconds ( if you set it to 30 seconds). But when the plasma battery explodes, there is a small piece left so it have to despawn before the respawn timer can start. That's why it take longer to respawn, you have to wait for it to despawn first.
