Thanks for your response. Here's the history.
03/29/02 Bought car new
07/08/03 11,488 miles Car won't start after sitting 4 days. Jump started and took to dealership. Tested charging and starting system and all functioned normally. They told us to not jump start but have towed if happens again so they can test computer to reviel the problem
08/19/03 11,567 miles. Car dead had towed. Dealership said faulty cell in battery. Replaced battery.
05/02/04 17673 miles. Started car and backed into driveway for oil change. Changed oil and car dead. Charged battery cause we had to move it (weekend) and took it to dealership next day. They checked battery, draw, and electrical system, no codes found. Asked them to contact Nissan which they said they did.
05/27/04 21,488 miles. Service engine soon light on so took to dealer. Tested battery and charging system found normal operation. Faulty oxygen sensor was reason for SES
11/02/04 22,558 miles. Drove car to town and around on errands. Took to car wash. When car ready it was dead. Towed to dealership. Tested battery and charging systems. Found battery to be shorted. Replaced battery.
04/20/05 23,298 miles. Drove to grocery store. 5 minutes and back in car and it is dead. Mfg. warranty expired 03/29/05. Towed under battery warranty. Tested battery and found shorted cell. We asked them to contact Nissan again.
04/28/05 -04/29/05 Took back to dealership based on their contact with Nissan. Performed electrical system draw tests on charging system, audio system, and antilock brake actuator. Looking for a draw of 50 milliamps or more. Tests found only a .43 milliamp draw which is ok and will not cause battery discharge.
04/29/05 We contacted Nissan ourselves and filed a claim.
05/05/05 Nissan Area Rep said he would not approve throwing parts on the car because they can't find anything wrong with it.

Has this been happening since new? May have bad diodes in the alternator. Depends how well they checked the alternator if they say it's ok. If not then it sounds like you have excess current drain while the car is parked. Have you ever left the car just sit for a few days without starting it to see if the battery goes dead? If so, you may have a short in wiring or some electrical component is draining the battery.
You need to check the current drain on the battery. To do this you need an amp meter. If you know an electrician, he might have a clamp on meter. If get a meter that will measure up to 20 AMPS not milliamps. Then disconnect the pos. post and put the meter in series with the battery and the cable. The reading you should get should be very low without anything on or doors open. It should be less than 1 AMP. Bear in mind that the radio and clock will draw current so remove these fuses first. Also the computer will draw a small amount of current.You can see the curent draw go up by just opening up the door for the lights to go on. What you do next is starty removing fuses one at a time until the current goes to zero. Hopefully you will find the excessive current draw. Good luck grafflef
