I have no info either, but will note that I have 2 extra plastic headlamps and a LED flashlight that takes double A’s wrapped up in Alum foil stuffed into my Faraday cage. They do say that EMP will not harm batterys, but if I have a device that is in the Faraday Cage (cough* metal garbage can cough) that needs a battery (ie Tescun 880 needs a single 18650), then that battery(ies) is/are stored in the cage as well so that it is easy to assemble to ensure operability when needed. Items that need charging are wrapped with foil (or a plastic battery case then wrapped in foil) and placed in a bag on top. The bag has a tag on it with the dates things were last charged so that they can be pulled out and topped off periodically.
I was pretty layed back on this and basically ignored it until I read that they had moved back into Cheyenne Mountain. Ho Lee Fuk man, that’s a huge indicator of whats what out there and it ain’t pretty. Ramped it up pretty quick when I saw that.
Faraday Cage - CHECK
Extra cash precious metals on hand - CHECK
6mo-1 year of extra food - CHECK
Weapons and ammo - CHECK
Rain barrels, filters and extra water - CHECK, CHECK and CHECK
Separate location that can be driven to in 1-1/2 hours or walked to in @4 days that would be much more survivable with no power than the city - CHECK
If it turns out we never have an EMP hit but we do have a massive earthquake, I’m sitting pretty good.
BTW, from the link above (nice link thank you) “Although many LED flashlights are likely to survive an EMP simply because of their small size, the sensitivity of LEDs makes the survival of unprotected flashlights less than certain. Also, many LED flashlights contain additional sensitive circuitry. The small flashlights with an all-metal case are the most likely to survive. Because of the importance of having at least one good flashlight when the power grid is down for a long period of time, it would be a good idea to store at least one LED flashlight in a nested faraday shield. ”
