Hello all. Bought a new 2017 F150 2.6 EB in November. Drove it a little and on a long trip in mid-January where it got super dirty. Cleaned it up well and just parked it in the garage. After 2 weeks got a message that it had gone in deep sleep mode. Well I figured ok it is turned off so I wasn’t too worried about starting it. That was 1 1/2 months plus ago and I read that all I have to do is start with key to exit that mode. Well when I turn the key - nothing. I check with my gauge and it is showing .10 charge. I hooked up my charger but battery will not take charge. Dealership said bad battery - try to jump start and bring it in. Any thoughts? Thanks. Raleigh.

 

Not sure where you are located, but given you got it dirty, cleaned it up and stored it, your climate is probably similar to mine.

I had a similar issue with my 2017 Expedition. After sitting for about a month I tried to start it one day when the roads were dry.
NOTHING! Put my meter on the battery and I got 0.3 volts!
Put a slow (3A) charger on it. Wouldn't take a charge.

Brought the battery inside for two days to let it warm up.
Put the 3A charger on it for two days and it came back to life.

Seems to work fine now.
But now I keep a float charger on it when it is in storage.

BTW, when you put the battery charger on it, be sure and put the charger's negative cable to a good ground, BUT not on the battery's negative post.
If you put the charger's negative clamp on the negative battery post, the BMS (Battery Management System) won't be able to keep track of the amps in and amps out of the battery.

 

I`d say jump or try to jump start it or just remove the battery and go to your local auto parts store that checks batteries for free. If they say you need a new battery and since your vehicle is still under warranty, go to your dealer and get a new battery.
Of course your dealer will check the battery as well but he or she does not have to know that you`ve already had an outside source check it. By doing it this way and keeping that first check info to yourself, you`ll know if your dealer is honest or at the very least trust worthy.

Have a great day.

 

Battery
• Check and recharge as necessary. Keep
connections clean.
• If storing your vehicle for more than 30
days without recharging the battery,
we recommend that you disconnect
the battery cables to maintain battery
charge for quick starting.

So this was copied and pasted from the Op's owner's manual. Scamming the dealer out of a battery because the OP failed to properly prepare the truck for storage is hardly the best advice. I also find it ironic that you are giving tips on how to see if the dealer is trustworthy when in fact he would be dishonest himself.

I've seen you on this site. I have respect for you and what you bring to this forum. I just think that your quoted post above is in bad judgement.

Perhaps you did not realize that there is a recommended storage procedure for the battery. If so please accept my apologies for any accusations inferred or otherwise.

 

Wow dude, you really went out on the deep end with your comment and to say that i`m promoting scamming the dealer out of a battery is just absurd.

No, I don`t accept your apology because it came after your insulting comment so just save it for someone else.

It`s not uncommon for these batteries or any battery to go bad before the expiration date and some F150 owners have reported such and they drive their truck everyday.

I`ve had my 2016 F150 sitting for over a month several times and at least 2-3 weeks every month or two without driving it and i`ve never had a problem with it starting and I sure didn`t follow the procedure you so kindly posted from the owners manual so that theory goes straight out the window.

 

My 2017 SCrew 5.0 entered Deep Sleep in late Feb and remained asleep for 3 weeks. I received the notification on my FordPass and had no flippin' idea what this was all about. Being a good Scout, I researched this state on several forums and was a little concerned as to whether it woud start -or even respond- when I got home. After these 3 weeks, which included several major snowstorms and intense cold, I returned home. The next morning, in a -5C sun, I was able to clear away enough snow that I could open the pax side door. The driver's side door was snowed in to a depth of 5 feet, so that had to wait until later.
The truck started on the first turn of the key, and has not given me a moment's problem since. Am I lucky? Probably, but I thought I'd post this experience just to let our readers know that sometimes, this Deep Sleep issue can end well. I share GABAR's thought in the last line of his post: mine sat for 3 weeks and started right up. I hope my experience helps others. Cheers all.

 

It probably has a lot to do with the battery SOC when you put it away. If you'd had a few very short trips, it might not have been fully charged. At any rate, when the battery voltage gets low enough, some chargers just will not charge. You can work around this by connecting another battery in parallel long enough to get the charger going. Once there is "some" voltage on the battery, the charger should work until the battery is as charged as it's going to get.

However, once a wet cell lead-acid battery is discharged more than 50%, they have received some level of damage, and they will never be like new again. Do it a few times, and they become toast. Worse than toast actually, as butter will do nothing to help them out.

 

I gave you an out. Yet you still stood by that statement. Then you took it a step further with words like "absurd" and "theory". Okay.

So lets break this down.
If I am correct a 2017 2.7 came equipped with a lead acid battery. AFAIK only the start\stop equipped trucks were upgraded to the AGM which were a little more tolerant to discharging mishaps. The OP mentioned a message, which to me implied the truck was also equipped with Sync Connect. That in itself leads me to believe that the truck was loaded normally for the first two weeks of that storage time. Storing the battery for two months while connected to ANY type of load is almost definitly going to lead to over discharge.
And you're saying that because it is not "uncommon" for batteries to up and die inside of their expiration date that the OP is reasonable to assume that the battery is to blame? The mistake of leaving a lead acid battery designed for vehicle starting connected to a load for two months without any type of charging has nothing to do with the failure?
Either you are truly ignorant about batteries or you felt compelled to defend your statement that I questioned with "what ifs". Your personal experiences with your battery are not the same circumstances as the OP. Moreover, if what you are saying about your 2016 is true, and you have Sync Connect, you should consider yourself lucky.

Either way, your response proved my original point further. As did the subsequent responses that also affirm that damage was likely done to the battery by the way it was stored.

The failure of that battery is not the fault of Ford Motor Company. It was clearly maintained improperly. There was a manual provided to the OP that outlined proper storage that would have prevented his problems. None of these statements are absurd or theories.

However, going to the dealer to claim warranty under the theory that the battery is/was defective is absurd.

 

The last time I checked, you`re not my father or mother nor do you pay my bills so I don`t need you to as you put it "Give me an out" .

I said what I had to say in your first reply to me and yes, i`m sticking by it. Just like a hit dog, you yelped when I replied back to your first comment and now you`re trying to save face with your silly attempt to make yourself feel good by bringing up AGM batteries and how they can be charged and discharged but the fact remains, your first comment was absurd.

Get a life little boy.

 

And out comes the name calling.
Despite all of this , I have respect for you and what you bring to this forum. My attack was never meant to be personal to you. Only your content on this post.
You win. I will reply no more on this subject.
Happy Trails.
