If your battery is a few years old maybe it can't hold as much charge and it drains it quicker.
I just leave the alarm off if I'm not using the car and rely on the keyless entry for security.

The alarm wont drain the battery if it is a volvo factory one. 50 ma is the max current allowed once the car has shut down.
