Seantsm2001 Mine look the same also only in the driver side. Passenger side is perfect

Anti-Medic I recently had this issue with my batteries. I just swapped them out. To clarify, it was only the driver side battery and I replaced both cause OCD.

villestrip I just had my batteries replaced under warranty a second time. I think I'm going to sell them and buy some Odyssey batteries since I'm at 27,000 miles. Anyone running the Odyssey 65-PC1750??

I bought some protectant to apply and keep it near the car wash stuff to remember.
both of the batteries in my 17 were damp on top, had horrible corrosion on terminals and the battery hold downs. with only 14,000 miles. ford warranty replaced both batteries and both hold downs for free. claimed bad leaking batteries

I guess that makes sense, I know cordless tools with the lithium ion don't like the frigid north either.

Guess I'll stick to the AGM

Where are you at? Up north lithium batteries aren’t worth about anything. They do not like the cold.

BrewScrew I've had to replace both of my batteries in the past year on my '17. Had bad corrosion as well. I went to Wally World and got the AGM Plats. 5yr warranty, Wally worlds are literally everywhere..

scha0786 I removed each terminal and installed one of them felt straps and sprayed them down good with terminal protector. We'll see how long mine last.

Based on the number of comments on the subject, it sure looks like Ford's battery supplier has a manufacturing or design problem with the post seals. And with the comment "it was Ford's fix for this common problem", while a TSB or recall may not be published, it's possible the FSE's are instructed in addressing the issue.

Depending on what the dealers are doing, some replacing the batteries with OE assembly line batteries which often are virgin lead, or the aftermarket Motorcraft batteries which are recycled lead (in the parts literature on batteries some are listed as non-warranty replacements), the issue may or may not continue. The safest thing is a different manufacturer until Ford throws a flag on the supplier.

This amount of acid leakage should not be happening today with an OE battery, IMO.
