Asked by Ed Nov 10, 2011 at 08:26 PM about the 2004 Saturn ION 1

Question type: Maintenance & Repair

About once a week I have a dead battery. I charge and load test the battery with a Blue Point digital load tester and the battery is putting out 105% of it's rated capacity. I have replaced the battery twice in 6 months. I disconnected the negative battery cable from the battery and put a multi meter in series. It is drawing about 5.5 miliamps of current after it goes to sleep. What is killing my battery? I also pulled the fuse out of the stereo circuit to see if the stereo memory is draining my battery. I still have the same problem with the fuse out.

good start for diagnosis. there could be a possible faulty module/connection that is waking up the vehicle after it goes to sleep. another thing to look at is the output of the alternator.typical system voltage while the vehicle is running and with accessories running is somewhere near 14V with a lot of loads and it running i'd tend to say 13.5v should be minimum

Thanks for your help. I have done the alternater test. Battery is putting out 12.9 volts with motor off. I then start motor turn on all accessories and it puts out 14.1 volts. I do not think it is the alternator. All the symptoms point to a bad battery. I know for a fact that it is not the battery because I even pulled the battery out of the car and sat it on my work bench for 2 weeks and the load tested the battery again and it passes with flying colors. I do however believe that the computer maybe waking up. It always tends to happen when its cold out. I have read some forums pointing to a relay in the steering colume and also the ignition switch. The car doesn't have alot of value so I don't want to play the guessing game by replaceing parts. Times are hard and I have a son in college so I need to figure out the problem before I start being a certified parts replacer. I am a certified boat mechanic (Mercruiser) so I have some basic knowledge how things work but this one is tough. Do you have any more help?
