Annoying battery drain

[MBR87GN]

I have noticed after the car sits for a few days the battery seems to be weak on restart.I thought it was the battery so I replaced but no luck-same thing.Checked the alternator-All good,so I'm thinking maybe a battery drain.I would appreciate any useful info on tracking this down.thanx

im going through the same thing-when you put your key to on ,does the volt light light up on your dash? if not check the bulb in the circuit behind your dash-this is what is draining your battery-matt
