[DML] Weak battery

[MDinu89900@xxxx]

Whenever my car sits without being driven for approximately two weeks and I 
go out to start it, it turns over to the point where it just gets enough 
juice to start or it fails to start until I let it sit for a minute or so. 
Once I drive it around, it get charged up enough to start with no problem. 
Absent replacing the battery (which I may do anyway) and the other obvious 
choice (drive it more often!), is there something that can be continuously 
draining my battery? I seem to recall something on the list about 
disconnecting something because of a drain on the battery but can't remember 
what. Thanks
