So, if the method was to substitute the batteries for ones containing explosives, then how were they triggered simultaneously?

Wouldn't this also require some additional HW/SW in the pagers to trigger the devices? Otherwise, if it was just battery terminals connecting to the battery, how would a remote signal trigger them?

Or maybe it's as simple as the adulterated batteries containing timers and thus not needing external triggering?
