Came out to dead battery yesterday (Optima yellow). I disconnected and charged battery then reconnected today and alarm started going off. Key fob would not stop it but It stopped on its own after about 30 seconds. Now I noticed my front turn signals (LED) are flickering about once or twice every minute with the vehicle off and key out..maybe that's what drained the battery down? Anyone ever have this issue or know what may be going on?
