Hezbollah thought going back to using pagers would help them
Only thing they went and got new pagers - pagers used by Hezbollah members were equipped with lithium batteries, which were likely responsible for the explosions - With batteries, a chain reaction called thermal runaway can cause the battery to generate even more heat and eventually catch fire or explode - the handheld pagers system was detonated using advanced technology that technology we don't know about
They shoulda bought 1-way pagers instead - 1-way pagers sold are powered by AA or AAA batteries - there mistake was purchasing brand new up-to-date pagers
if malware was used, which some say was used, you could potentially gain access to a device's battery management system, which controls charging and discharging, and issue commands to rapidly overcharge the battery or prevent it from regulating heat dissipation properly. This could lead to the battery overheating and potentially catching fire or exploding.
If a Hezbollah pager shipment was intercepted that malware coulda then been put on they pagers - again some say that happened
