Battery charge?

[Gjkrisa]

Hi how long have you not driven your Taurus and still had charged battery
My car can go about a week after that most likely will not start from low battery.
Thinking of adding a yellow top to at least not worry about to much wear on the battery although after one year levels are still good and the plates are still clean and use a smart trickle charger in the winter and will continue thru the summer as  well.

It's my DD So 365 days a year IIRC. LOL.Z
I actually read somewhere that there is a threshold of two weeks and anything longer than that the ground on battery should be removed.

Yes having to worry about the battery after a few days when the car was brand new was very annoying all I had in the car was 2 blackvue dash cams now that I've taken the rear out seems I get a couple more days Which in that time usually drive the car some more.

I've read just having the key fob near the car can wake up some of the electronics often so also may be the issue as I've moved and not so close to the car all the time.

After 3 days my ctek battery meter says battery at 71% which just after the first day of sitting gets from 80 to 70 from a full charge.

Hmmmm... dunno about the key fob thing... I literally keep my key fob in the key fob holder in the center console ALL the time.. never comes out... but mine is a 2010...

Maybe being in the holder it won't cycle since it knows where the key is already instead of varying signal strength? Also year could be effect.

First time battery has charged its self without using the trickle although not fully

Maybe time for a new battery, might as well have them check the alternator as well.

I think ambient temp has had alot to do with the battery. At least last oil change Ford looked at it and said everything was working good that the alternator was putting out 650amp but it's worth a second opinion in person . Be odd to have a shitty battery or alternator from the factory as I ordered the car.

Whoa, 650 amp alternator?  Give me one o those!  But yes, ambient temps affect battery charge/rate.  That's why on my NICO charger they have a setting for "normal" and a setting for "cold weather" charging.

X2 only have a 220 Amp on mine. LOL.
I do have a Motorcraft 850 Battery though. Z

Your fob being just at edge of range or going in/out of range are what will wake the car up. 

Other than when you are using the vehicle I would not keep the fob in the car or right next to it (hanging by garage door etc)  If it is close enough to sense then everytime you go by car it could be waking up systems thinking you are going to use the car..?  Just a thought of something to try and see if it helps.

That's at least what the service guy tries to say but I guess it's just what the battery is rated for not the alternator.

Looking at the alternator it probably barley produces 350 amps

So I finally managed to get the modules reset by putting the car in inop mode using forscan the next day still had a very high battery draw but then the second day the draw was gone and had since not come back battery at 100% next morning. Did find out from Ford that the modules are supposed to shut off in 40minutes with everything closed doesn't matter how close the keys are not if the doors are locked or not.
