So, what size is the battery that’s required for this to operate?

[petro45acp]

EMP renders all electronics inert....

smart guns (fail-safe = non inoperable?)
cameras
door locks
Gun safes with electronic locks

KYPD

My guess is lithium or they might use a disposable 12v L1028. Those can power a lot of RF but they don’t last. So they would order 1000’s and replace them regularly.
