Take it to Autozone or some other parts store and get them to check the charging system for free. They will probably find that your new battery is actually already bad, or something else that will help solve the problem.
The security system on an EX is part of the Multiplex Integrated Control Unit (MICU). You can't really disable the system without affecting other circuits.
I noticed from your photo that the hood is opened. Is there an issue with the hood not always latching? If so, the security system not acting "right" may be due to the hood switch. The way the security hood switch works is when the hood is open, a ground signal is allowed through the switch to the security/multiplex control unit. Normally, when the hood is closed, there should be no ground signal coming from the hood switch. If the hood was closed and the security system sensed a ground signal from the hood switch, it sounds the alarm because it thinks the hood is open.
You can just disconnect the 2P connector to the hood switch if that was the cause of the false alarms.
