maybe when they got the call from a certain number - maybe owned by the c-130 loitering nearby - i think they changed the software and added a relay that shunted power from the battery to a blasting cap when the right phone call number came in - i don't think it was battery heat ( notice the battery doesn't look burned it looks impacted and mangled

from amir tsarfati :
EXPLOSIVE DETAILS: According to Sky News Arabic, Mossad placed 20 grams of PETN explosives into each device. PETN is sensitive to heat and friction, and Israel detonated it by raising the temperature of the battery to explode it.
