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...

I've had my 2014 Focus for 7 months and 6000 miles and often gives me the same message. I have the basic 6 spkr system and Sync. Sometimes I can detail my car w/o it powering down, but other time it can be anywhere from just a couple to 10-15 minutes. The dealer checked the charging system, says all is ok. I appreciate the "fail safe" system but it is annoying having to start my car every 5-10 minutes while detailing.
Nothing else is on but the radio when this happens. Even with the radio off and I'm sitting in my car in a parking lot reading while waiting to go into work, it will still shut off. I would have the key off but like to leave the phone hooked up to SYNC in case I get a call.

joshuafail I have my radio on all the time when I detail, and I have the Sony system as well. I've never gotten that message before and have left it on for far longer...

Fun trick though, if you leave the car completely off and just use the power button on the head unit to turn the radio on it'll turn on the system for about 15 minutes. If you want longer you can use ACC mode (first click of the key in ignition/button press w/o foot on brake) but the open door chime won't shut up.

Irish614 Not to hijack a thread but I see its been 2 years roughly since anyone has replied. I have a 2012 focus sel hatchback that keeps saying battery low check handbook when I open my door to get into the car. It goes away once I start and drive. I checked the battery and it is giving out 11.9-12 volts, when I start the car it obviously goes up. Anyone have this issue? I don't have the mft so that's not causing the issue. I do have a 12" subwoofer with 500 watt amp however this happened after I took the subwoofer out.

If I remember correctly, the mk3 Focus uses a 96R. It's a pretty small battery, relatively. It really doesn't surprise me that it is drained fast.

sekazi I also run on battery when I arrive to work but usually for no more than 10 minutes. Today was about 5 minutes with the radio on a iPod via USB and volume set to 8.
Before = 11.8v
Ran from 12:10 pm to 12:28 pm in ACC mode with blowers at 4 and radio at 6. If it makes any difference it was FM HD.
Ran from 12:28 pm to 12:56 pm with everything off except the radio and it was set at 4. FM HD still
After = 11.4v

So I was on battery for 46 minutes and dropped 0.4v.

sekazi What I can do is tomorrow I will get the battery volts of mine. I use my car usually about 50 minutes a day in battery but tomorrow will be about 30 minutes since it is Friday. I will get the battery volts before and after. Then Monday I will do the same except with the car in ACC mode.

PratoN My car did this a few days ago as well. 15 minutes in the car (no HVAC or lights - just MFT and bluetooth on) and I got the low battery message.
