Who knows what can I do?

I bought around a year ago a new battery from O'Reilly and when I don't use my MSP6 for three day in a row the battery is dead. O'Reilly checked the battery and they say it's OK. My friend checked all my electrical system and he didn't find nothing wrong. What can I do? Can somebody help me?

Did you happen to accidentally leave a light on? or do you have anything that runs constantly on your car?

I checked all my light and nothing is on and I don't have anything runs constantly

Do you have any aftermarket gauges? If so how many and what are they wired into?

Yes, But I Install them like one year ago and I disconnect and still the same problem

I have to disconnect my battery if I'm leaving the car sitting there for longer than a few days. I have no idea what kills the battery either. Had mechanics check everything and they were also puzzled. blargh!

i wonder if it has anything to do with the anti theft system that is built in the car other then that im came to a brick wall

If you didnt find it yet, use a meter on the battery to check the draw when the cars off. If its high, pull fuses like your radio, lights, etc until you see the draw drop.

Thank everybody for your advice, I swap the battery and work OK. I put a new one

I was going to say I'm running an optima battery and if I leave mine sitting for a few days it cranks no problem. Could be just one of those things. Glad you got it fixed though.
