2012 Focus Titanium "Low Battery see Owner's Manual" after 20 Minutes of Stereo on
 
Hey Everyone,
I wanted to see if this problem is normal for the Focus under the given scenario.

So, I like to listen to music in the car (2012 Focus Titanium) while detailing it. I have the Sony 10 speaker sound system and after listening to the stereo (USB) at volume 9 or ten for about 20 minutes I got a message on the screen that says "Low Battery See Owner's Manual" I can't remember if I had accidentally left the fan on (i know it would make a difference) but on another instance I got the message after 40 minutes of music playing (went into battery saving mode once and I had to turn it back on) with no fan on.

I guess I can accept it if we just have a very weak low capacity battery but I used to listen to the stereo on my Mitsubishi Montero (same wattage stereo) with a 5 year old battery at the same or a little higher volume for a very long time (well over an hour) without it ever draining past being able to start or even a noticeable drain.

Just seems odd to me that a brand new car would be so inefficient or have such a bad battery. I know the stereo probably uses a lot of juice but...

Thanks!

Or the car is being conservative

I have only had this happen once and I had the Fan Blower a little over half way and the stereo on about 6. Additionally at the time I didn't realize that the Sun Screen was making the auto lights come on and I got that message ~20 minutes in.

Since then I try to remember to make sure the lights are off and do not use the blower for as long. I have yet to get that message again.

EDIT:
I usually am running on battery for ~50 minutes a day during the work week.

Hmm, Maybe the power usage between 6 and 10 is a big change because the first time it happened was with no lights on or fan it was 40 minutes in (like I said I had to turn it on again after battery saver mode came up once).

Deftmetal might be right as well though, does anyone know how it gauges the low battery? Because I've not required a jump yet. Usually when the message pops up I freak out and turn the car to drive around for a bit. Never had it have a problem starting after the message though I have never left the radio on after the message.

So, I'm assuming you have MFT and the push-button start (I think all Titaniums have that). Are you just turning on the MFT (pressing the power button on the stereo), or are you turning on the ignition (pressing the start button without pressing the brake, turning on all the cluster lights, etc?)

Reading the forums, you can do the first to get the stereo on without the rest of the vehicle. If you do the second, you're going to be powering up a lot of other stuff (climate control, fuel pump, etc.) that will kill your battery pretty quickly.

Start your car in Test Mode by holding the left 'OK' button for a few seconds and then while still holding the button start the car and continue to hold for another few seconds. Once test mode displays on the screen between the guages, use the up or down arrow to navigate to the battery volts screen. If its below 12 that's an issue with a bad battery or faulty alternator. I think mine is actually always around 13 volts which seems a little high actually.

Good luck. If it happens again take a pic and bring it to the dealer.

Now this is all just speculation as I'm no engineer, but I'd think the Sony system in this car would drain the battery faster than a traditional car stereo of yore. As the Sony system contains MFT, you'd be running the computer that powers that system as well as that large touch screen. As others have said, even if the fans were off, it is possible that the computers for the climate control system were running. If you happened to have the door open for a period of time you'd make things even worse as the fuel pump primes itself when the drivers door is open. Oh and the Sony system has a subwoofer, those things are hungry.

Pressing the button puts the car into accessory mode so you get the blowers, radio or anything to do with the MFT along with any lights. Pressing the brake and then the button will start the car so you are using gas not the battery.

I don't think it's a true accessory mode, if it's running the fan, headlights, etc. It's basically turning the ignition "on" without cranking the engine (equivalent to position II with the key).

I think the OP just wants the stereo (what accessory mode should be), and I think you can turn that on separately without powering up all the other stuff (which will make the battery last considerably longer).

On a normal key ignition ACC and ON is the same thing up until you hold the brake and move the key to RUN to start the car which then it goes back to ON. At least that has been the way every car I have ever driven works. Blowers have always worked for me in ACC mode on a key or push button.
