Battery Voltage
The other day I got to start the car after it's been sitting for 2 weeks and had some of the functions not working due to low battery voltage. Car drove fine no issue after a few minutes and hasn't really given me any problems since. When I'm driving its at 13.-14.1 and the reason why I'm posting this is I decided today just for the heck of it to look at the voltage and when I was turning to key to turn the car ON it dropped to 10.2-10.5.

Either a weak battery or there is a amp draw while it sits. I've read here before of people having issues after the car sits for awhile. Most will keep a battery tender connected while it's not being driven. I do this also.
If it were being driven everyday you may not even notice it.

ya so far it goes to about 10.1-10.5 during crank. I think just not driving it for a couple of weeks and hooking up the camera to turn on when it detects someone there put a strain on it. It's not a new batter being from 2010. Next month ill just change it out for piece of mind. I would do it now if I didn't have a couple of issues with my E550
