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.

They say the My Ford Touch system uses "that much" power... I'm stunned too because I could have my previous car on battery for hours listening music as well. And though it didn't have the big touch screen it still had a premium sound system with a better/bigger sub woofer and I can only assume it was far less efficient than the Focus. 30 minutes of radio is just unacceptable, I use the radio while detailing my car a good detail is not completed in 30 minutes...

When I get my oil changed from the dealer I bought it from in 4k miles I'll tell them about the issue and see if they can replace the battery. Think the place I went to isn't the best dealership, they act like I'm annoying them when I have concerns about my car, as if they weren't getting paid by ford to perform the work...
