I don't drive my 2013 GT much in the winter so its in the garage most of the time.and I think I may have a battery problem if I dont start it for a couple weeks its almost dead have to jump start it.I can go months on my other cars.anybody else have this problem.

 

Buy yourself a battery tender. It will keep your battery fresh. You can get one on Amazon for about 25 bucks.
I would think that there are things on the car like the radio that probably constantly drain the battery, even when not in use, though I could be wrong.

 

Mines been sitting since Nov and battery is fine. Just opened her up today. It doesn't get colder than 45* in the shop though.

I have a Battery Tender Jr I plan on hooking up in the next few days though. Is your car all stock? No phone chargers, or anything plugged in?

 

I keep all of my vehicles that I don't drive on a regular basis on a battery tender. I use one on my ATV as well.

Battery tenders are great and will prolong the life of your battery.
Having said that, mine sat from Jan 1 to mid April and fired up like the day I put it away.


This year I plan to run it to operating temps every couple of weeks. (recommended by Ford)

 

I let my car sit for 3 weeks and I just had to have Ford replace my battery. I have no clue why a battery wouldn't last for a month in the cold. You are not alone. My ATV starts right up every time and it sits right next to my car.

 

It's from the parasitic draw from all the electronics, keep alive memory, etc. Same situation with most vehicles.

You can put it on a batter tender like these guys have said or simply disconnect the negative battery cable. Disconnecting the negative will instantly stop any parasitic draw or discharge.

I've had vehicles in storage for over a year with nothing more than the negative cable disconnected and they fire right up once reconnected. My 2014 has been in storage since November and all I did was make sure the battery was fully charged, and disconnected the negative terminal.

Dealers do the same thing with their vehicles because they know the batteries will discharge if left connected. Same deal with new batteries you can buy in the store. They are charged and then just sit there until someone buys one. The battery in your car should be no different with the negative terminal disconnected since you have broken the circuit.

 

Hi mackman107,

These guys have great information about this. You should also check out our vehicle storage information in your owner’s manual, 3rd printing on page 258.

If you don't want to buy a battery tender for your car then just disconnect one of the terminals from your battery and reconnect that same terminal when you want start up your car.

Once you start driving the car in the nice months of the year the battery will recharge itself to the maximum level.

I had a 2001 Mustang GT and eventually sold the car in 2008 and the battery was still fresh after this same process and the purchaser was very impressed that I still had the original battery in the car.

Pretty much fool proof and should solve your problem.
