i had a bmw alarm fitted , and then i had the battery start to do flat after a few days. Unless you useit everyday , you need to put a optimate battery charger on it bud ,

If the alarm is disconnected, then it's not that. With that still disconnected use an ammeter to find what level of drain is on the battery or get someone to help out if you're unsure.
How old is the battery? 9 weeks? What type of Battery? Possiby a duff battery but should be easy to diagnose.

Battery

Just disconnect it completely for a few days and see what happens then if it goes flat then it's the battery.
