How much current should there be with everything turned off?

My battery goes dead after sitting for 4-5 days. Battery is new and good, alternator is good. I measured the current to be 129mA meter.

I pull the BCM fuse and it drops to 29mA. Any ideas?

get yourself a new battery

Please read the post and not just part of it.

Yes, current is 129mA. The engine is not running. The battery is new! It works just fine if it doesn't sit for a few days.

"get yourself a new battery" if you don't have anything to post that is worth while dont' post it. Right back at you.

hey, i think he was just givin you what you deserved. you just brought up old random threads and had nothing to contribute.

besides, you asked for any ideas, and it's a perfectly logical idea. perhaps you got a lemon battery. it may be worth it to swap another one in to see if the problem leaves.

Been there done that with the battery thing. I needed to post a thread and I haven't been around military and all. So, give me a break. I didn't make the rules on 15 threads. I need to get back into the swing of live living in the sand box is not the easiest thing you know or not? I just have a problem with my car and I'm looking for a solution. I don't like to go to the dealerships as do all that are here.

Back to the orginal question, does any one know how much current it should be drawing with nothing turned on?

the man is right ... you probably have a lemon battery

I doubt you have a bad alternator but its possible ...

lol go to autozone or advanced auto parts and get a free charging system check genius

you ask a question for something as simple as this, your gonna get many different answers

Have you alternator tested again. Your alternator is responsible for recharging your battery so that it does die in a few days. Examine you betls, and make sure all pulleys are spinning.

In this case it would have to be your alternator or battery, unless there is something that is sucking the power out of the car.

You probably have a bad battery Autozone or many other parts places can do a load test and tell you for sure. The battery has to be fully charged for this to be accurate so if you go in they may have to charge the battery a while before they can test it.They can also check your alternater at the same time. Autozone or Advanced Auto Parts both will do this at no charge where I live.

While the car is running with an ohm meter you should be running around 14.1 volts or a little more. Shut car off, disconnect the battery, reading should be over 12. Don't drive the car or start it up for a few hours, then check it again with an ohm meter. If it have dropped more than .4 volts then I would say the battery is on it's way out even if it is new that's why batteries come with warranties in cases like that. Only other thing I can think of is the cable that goes from the engine to the battery tray (I've heard of people having corroded ones causing the battry to go dead quicker). Good luck.

Voltage is not a good indication of battery performance as it checks it without a load. Batteries when they are dieing build up huge interal resistances, so under load the voltage drops hardcore on a dead battery. This is why we say have them check it at Autozone or what not, as they test the battery under load, which is a much better test.

Also, how were you measuring the current? If you measure between the two terminals, you won't get a reading that means anything at all. You have to measure current in series, voltage you measure in parallel.

Your car battery is probably rated at least at 60+ Amp Hours, so at 129mA, it would take 60/.129 hours to drain, which is a little over 19 days. Better batteries are rated closer to 100 Amp hours, which at the same .129A load would take over 32 days to drain.

Wow sounds like your battery sucks!

If your battery dies while ur car just sits there than either you have a bad battery or a shorts some where that is draining your battery. go to an auto parts store and have them conduct a free battery and alternator test
