RGVAL This forum is great ! I found the same issue on the positive terminal on the passenger side. One cell was dead purchased new Interstate (Costco $118.00) Tried to (rebuild Terminal)but still some corrosion starting. Thank you ford_doctor for the part number. Only question who/where can I order that terminal part number?

Still waiting any help on my "Door Ajay" issue

CajunMick Try this - when installing the clamp to the post, let the top of the clamp sit flush with battery post top, which leaves a gap between the bottom of the clamp and top of battery.

I notice the pass side battery clamp has a gap at its bottom, and very clean, yet the driver side battery clamp was resting on top of the battery, and it was full of that green junk. I removed the clamp, cleared off good, reinstalled it, flush to top of battery post.

And I sprayed a lube/corrosion control fluid on it. Seems to be working ok.

ford_doctor Boiling water melts away heavy corrosion deposits almost with magical ease. Neutralizing can be accomplished with baking soda as mentioned... of course, you can neutralize just about anything (relevant) with enough water. Here are some examples of crimpers----> Battery Lug and Terminal Crimping Tools | Automotive & Truck Aftermarket | SARGENT Tools

jsh-f250 I have used the coke option many times for the terminal corrosion. But what about cleaning the actual end of the cable before crimping the new terminal. Is it even necessary. Would think so to ensure good connection.

Stroking it Backing soda is the best way to naturalize acid. back in the day we poured coke or pepsi on the terminals because of the soda content.

jsh-f250 Thank you ford_doctor. I have ordered the BT4Z-14450-AA clamp. May have to buy a crimper for that size if wire and clamp when I pick up the heat shrink. Whats the best way to clean the cable end?

Hopefully this solves the starting issue. I have found that if I shutdown my truck while the AC and radio are on. It will not start back up. I'll remove the key and then try again, and so far it starts. But if I turn off the AC and radio prior to shutting down the truck, it starts right back up? This seems a little crazy to me.

Are you gals/guys seeing the same and if so, what are you doing to limit/prevent it? I had not coated the terminals previously, but I added a light coat of lithium grease this time.

Thoughts welcome.
Your batteries are leaking and no amount of Di-electric grease will stop that. I just replaced my batteries because one was leaking and the other one was 3 years old. The 3 year old one was leaking after one year so that is why I didnt change both at the same time. Cost me $260 for new batteries. kept the 3 year old battery encase I need a spare in one of my cars.

If your battery is leaking acid is running down the side and rotting out the battery box. It may be getting into the heat wrap if you have that on your batteries like the newer trucks.I didn't read the whole thread until now but my information is for the general people here. If you got a leak it needs to be fixed.

I have bought 3 brand new Fords and all those batteries were junk. They all leaked within the first year. If I ever buy a new car again that will be part of the deal swap out the batteries for new ones

ford_doctor SSM 47886 - 2012-2016 F-Super Duty - Battery Cable Clamp Corrosion Repair
Some 2012-2016 F-Super Duty vehicles may exhibit a battery cable clamp corrosion concern at the positive battery terminal. It is not necessary to replace the complete battery cable harness CC3Z-14300-A for this concern. Positive battery cable clamp BT4Z-14450-AA is available and can be used to replace just the corroded terminal. Do not cut or shorten the battery cable, but instead remove the corroded battery cable clamp and clean the cable end as necessary. Bend the new battery cable clamp as needed and crimp it to the existing battery cable. Make sure to use heat shrink tubing over the battery cable to battery cable clamp connection. Obtain the heat shrink tube locally.

jsh-f250 I know it's an old post, but hopefully someone can help me find a part.

I have a 2013 PSD and have been dealing with excessive corrosion for the last few years. I would check the terminals regularly, but on one inspection I found the passenger side terminal completely corroded even though I had the fabric discs and I had sprayed the terminal. The corrosion was so bad that the terminal needed to be replaced. Of course Ford said I had to buy a new cable assembly and it would cost $2600 to replace. I found a work around but now I having issues with the truck not wanting to start and throwing all kind of fault codes and the wrench symbol. Had the batteries checked by NTB and Ford, both said they were good. Ford says its the work around terminal and I needed to replace it and see if it solves the issue. So, I'm looking for just the terminal end or terminal some of you may have used. As you know, you have very little slack to play with. Any comments or suggestions would be greatly appreciated.

Another question, can you crimp an extension onto the cable to have more slack? What gauge is the wire?

JESSE 1 My passenger side battery started corroding. I cleaned everything but it immediately came back. I took it to the dealer and they replaced both batteries under warranty, also had to replace the battery tray on the passenger side.

KReeves Both batteries on mine were corroded. Both posts were leaking and had to replace them

RT Glad you got it fixed. Something weird is going on at the battery plant. I hadn't seen a terminal ruptured like that in 50 years and now I've seen a half dozen in one year.

I had a check engine light come on and while at the dealer, I explained what I was experiencing. In the end, both batteries and all of the hold down hardware had to be replaced; they were both leaking around the posts. I thought this was pretty bad for batteries which were only 16 months old. Happy though the warranty covered everything--the mass air flow sensor had also failed (check engine light issue). All is good now.

hawkerpilot05 You want to stay on the cleaning of the battery acid. My wife's Ford Explorer had this. Even though she does all her oil changes at Quick Lane, Ford never caught it as it is under the plastic cover on the post. It corroded half of cable connector. Even though you can take the connector apart, Ford only sells the whole assembly. A year later, again after an oil change, it corroded up again and the connector was shot. Fortunately she had a Ford Extended Warranty and they cleaned the battery and replaced whole cable assembly. I then bought a new battery and used dielectric grease and no problems. I have been told sometimes a small crack at the post will causes acid to gas out and cause this. Either way, since new battery, no problems. Some people also suggest to get this fabric rings that go over battery post and then terminal goes on. This worked at stopping corrosion on our Ford tractor.
