missing and meter at 8 volts and failed load tester. Charging circuits are fine on aes and facp. Facp batteries load tested fine . AES radio key lock is busted possible tampering happen? Replaced aes battery and confirmed the 801 restoral that alarm center keeps calling about. They said the low battery came in December 7th and now reports daily of non restoral. But all should be good now as they got the restoral after battery change. See pictures for battery looks like someone tampering with it.
