Can be the battery has a dead cell which will require the battery be replaced. Can also be anything on the vehicle that is on pulling from the battery. Any light that is on or any relay that is stuck will drain the battery. Check under hood light, trunk light, glovebox light, interior lights, etc.

What would cause battery drain in 1998 Ford Taurus?
The number one cause of the battery drain you describe is the battery itself. Remove the battery from the vehicle and clean the battery exterior and the area the battery sits in with baking soda mixed with water. Clean the battery cable conections and re-install the battery. While it's possible something is staying on or activating and draining the battery that's a much less frequent occurrence. You should start by having your starting and charging system checked. If you express to the shop that you're concerned that something may be draining the battery while the vehicle is off, they should also perform what's called a "draw test." While some items (such as the clock) remain on even though the vehicle is off, their power consumption is low. Performing a draw test will tell the technician how much current is flowing while the vehicle is off. It should be less than 50mA. Anything 100mA or above is cause for concern. Look at, of course, dome light & courtesy lights, glove box light, trunk & hood light. Also in very rare instances you may have a power window switch stuck in the up position. Even rarer would be a power door switch stuck. I would suspect you need a new battery, especially if the battery is over 3 years old.
Something is draining your 2003 Buick Le Sabre battery the battery has been checked out numerous times is a good battery the car will sometimes go for two or three days and the battery will be fine?
Install a test light in series with the - battery cable. If light is on there is an active circuit in vehicle. Remove fuses one at a time until light goes out - that will be the active circuit. could be trunk or glove box light or other hidden accessory. At times the voltage regulator circuit will not open on vehicle shut down - which would cause a drain on the battery.

That would be short for "generator" light. If that light is on while the engine is running, the charging system is not working and you are running off of battery power only.

If it is your voltmeter that drops while the vehicle is running. Most likely the alternator isn't putting out enough volts.
