Yeowch, that's pretty bad. You can clean it up with some water and baking soda, but I'd bet there is a crack in the casing underneath all of that allowing the gases to escape.

buy a new battery and a new cable end and be done with that mess!

I went to an auto parts store and bought a battery terminal clamp with a clamp for a large gauge cable, $5.
The original battery clamp just crumbled under any tools. I had to pry it off with my hands. I used vinegar to clean up the mess.
Always remove the negative first.
Hope this helps.

Replace the battery, its leaking or wicking acid up causing that.

Had this issue on my 2016. Terminal snapped off and the post actually separated from the battery. I read somewhere that the battery’s were notorious for bad post welds. Ford replaced battery and positive terminal under warranty.

My son just had this happen to his 2018 GT. Drove around all day. Later that evening went to start the car and got clicking and flashing lights. When he took the battery cover off the postivie terminal was smoking. I'm guessing the voltage was valid for the ECU to try to start. There was so little cable left that the current capacity was too low to start, but instead heated up and was melting the red cover. I went over to give him a lift for a new battery and after lossening the positive therminal, a slight lift on the positive cable and it came apart. Thankfully a few months left on the warranty.

Had an issue w this on other car. I used Coca Cola and a brush. It looked brand new, rinsed with water after.
But didn’t eat my cable off, just was acid all over the terminal. Google said it worked and it did

Ford has replacement positive and negative cable ends (and an SSM for it) if you want to keep it somewhat original. For the positive you have to get a bit creative as it won't hold both the cable to the stater and the BJB and the red cover will not fit.

were they able to replace the battery terminal end or did you have to have a new harness entirely put in? This has just happened to me.

Constantly look for corrosion and dirt on your battery terminals. It is essential to clean them if you see that they have corroded and gathered dirt. The finest cleaning chemicals for severely corroded battery terminals are white vinegar and baking soda. Avoid using apple cider vinegar for this task, though.

Is this a do it yourself or a dealer fix? My positive is really bad. Thanks
