I believe the problem is that plastic explosives and a trigger mechanism look very similar to the cells and relegation circuitry in a NiMH or LiIon battery so an X-Ray can't really distinguish them.

What does this do to people with extra batteries? Do they all have to be charged? Would you have to put them in your phone/laptop to prove it?

What about modern laptops that have multiple discrete batteries (i.e. modern Macs) - I would guess that you could remove 2-3 of the 4-5 packs and still have a "functioning" laptop, albeit with a much shorter uptime.

I would assume it's an effort/sophistication thing, just raising the minimum bar to weed out/discourage people and lessen the number of attempts in total.
