Hello Fellow Stang'ers

I have a 2013 GT Convertible Prem. Recently I had parked my Stang (underground garage) for about 3 months (Winter period). Over the weekend I got theinsurance and decided to take my baby for a ride.

Battery, of course was dead (lesson learned have a battery tender during parking months). Once I juiced up the battery it started like a charm. I got it out for a spin (about 15-20 mins) and then parked it. I tried to start the car again and battery died again.

Basically, i have to juice it up everytime i have to drive the car.

Please help what should i do? get a battery tender and charge it up to 100% OR replace the battery? I hope its the alternator

To me this is really odd for a new model vehicle where battery dies so fast as I never had any trouble before with my Stang's battery.

Note: this is the first time i had parked her for Winter period.

cheers
Hans

Unhook the battery when you leave it for long periods of time.
You probably didn't drive it enough for the alternator to charge it (I doubt).
It is likely you may need a new alternator. Take your battery to an auto store to get it tested.

Thanks for your help. I have an appointment with my local Ford Dealer for oil change so they will check the battery condition.

I always thought this was the problem on old cars not for newer models. I will make sure not to leave it like this next time. Will use Battery Tender or unhook the battery.

Another thing I forgot to mention it gives weird electrical noise once i removed the key from the ignition after my 15 mins drive. Totally freaked me out thinking my car had been haunted.

your battery is junk, it went dead over the storage period, once a battery goes dead the acid will freeze, the liquid expands as it is a water solution and this damages the plates inside.

If a battery is left completely discharged for months it will never hold a charge. Even a good battery that has been discharged to zero even for a shorrt perion will never charge up to 100%.

Battery more than likely. The batteries these days aren't good for much more than 3 years.

Battery...

There is a small draw on the battery even when turned off. As stated, if you left it long enough for the battery to go dead and stay dead for a period, it's likely gone.

Battery is toast. When it is left discharged that long the cells go bad.

The last battery in my Focus was still kicking at 5 years.
