crossfire battery problem please help!!!
i own a chrysler crossfire 04 limited coupe and i have to jump start my car every morning because my car dies, i recently replaced the battery 1 month ago and its still dying , im wondering if its the alarm but im not sure. can someone please help? thanks
Re: crossfire battery problem please help!!!
Some have found this to be caused by the OEM radio, but the only way to be sure what is draining is to hook up an amp meter ( cheap multimeter on the high DC amp scale ) between the negative battery terminal and the cable.
Start pulling fuses in the underhood fuse box one at a time while watching the meter.
When it drops back to somewhere around 30 milliamps, you have found the source.

Re: crossfire battery problem please help!!!
All you can do is measure the current. Up to 50 or 55 mA (that is, .05 to .055 amp) is fine.
I'd guess that if a new battery went dead over one night, you will see maybe 2 or 3 AMPS when you measure it.
CAUTION:
1) Always have the trunk and doors closed when trying to measure the current.
2) Once you connect the meter, the various systems in the car must "die out" after the power is on. SO, connect the meter and ignore the reading for 30 seconds, after 30 seconds the various systems will be "down" and the current you then see is the real standby current.
3) Key in OFF Position and removed for these measurements.

I've had Bluetooth OBD dongles in my newer cars (Crossie, Jeep) for five years and have left for over two weeks with no issues. Good one will shut down until awakened by ignition.
Also my computer cars run about 20 ma when shut down. Spec says "under 50ma", 200 ma will kill a battery in 3-4 days, 2000 ma (2A) overnight. Cars I do not drive often stay on a little float charger.
Used to have to change at least one battery a year until I switched to AGM. They last much longer.

I'm somewhat surprised that folks would leave a Bluetooth code reader/scanner plugged into the OBD2 port. I've also got a Bluetooth code reader/scanner (BlueDriver) and it stays in my console in case I need to use it when "out & about". It connects to my Cell phone (which I nearly always have) and/or to my tablet (which I take on trips). Just doesn't make sense to me to leave it plugged into the OBD2 port.
I seem to recall that the BlueDriver powers up immediately after it is plugged into the OBD2 port. By powering up, I mean it begins searching for a Bluetooth device to connect to. Maybe it will pull a drain on the battery if left plugged into the OBD2 port. But I think as long as it can't find a Bluetooth device to link to, it won't stay on. But these days, there is always a Bluetooth device somewhere nearby - the device just isn't able to connect because of a lack of authorization and software. But it may keep looking! Others say it won't consume power unless ignition is in "power on" position. Gotta go back & read the paperwork for the device now - I'm curious.

That's why I prefer the UltraGauge wired, it turns off and does not drain the battery.
