My battery only lasted 6 months, brand new car.

Duuude, that looks like friggin Bleu cheese! Lol.There seems to be a thing with the batteries and cables. One morning about a year and a half ago, the Mustang wouldn't turn over. Batteries usually only last 3-4 years here because of the heat, but I had the battery checked twice a year with the routine service. It had passed only a month before. I had looked in the battery case occasionally, but as it turns out, the service dept checks battery through the diagnostic, and didn't visually.
AAA came by, cleaned the cable and jump started it, but strongly suggested Ford look at it rather than them replacing it. Took it in, showed them the corrosion and AAA service recommendation. They cleaned the battery compartment, replaced the clamp, cleaned and sprayed an anti-corrosive on the cable, replaced the battery and installed it with the anti-corrosive felt pads.
I picked up an aerosol can of that red anti-corrosive and used it as well.. I also check the battery visually now every fill-up- and I wipe it down. Despite that, 6 months ago during routine service, I was told the "new" battery needed replacing as well-fortunately under warranty. So yeah, that's a thing. (photo is of original battery issue, it never looks like that now ;) )

mine tooMy 2019 GT is three years old and my negative terminal is still as clean as it was when I got the car
Usually this happens because someone overtightens the terminal bolt and it creates micro cracks in the plastic casing around the terminal. Not always mind you, sometimes shit just happens. But usually there's a cause when you have that much blue cheese.My 2019 GT is three years old and my negative terminal is still as clean as it was when I got the car
GT isn't affected, I have an Odyssey AGM in mine with no issues. It's an uncommon size though, so there's only a few options that are a direct drop in.I thought I saw somewhere on the forum that the AGM batteries don’t fit properly with the factory battery cover? Might’ve been over in the GT350 or GT500 section? Just curious if anyone has had fitment issues
I changed to AGM after the first year. The OEM Battery was pretty dinky considering the amount of power this car can drawUsually this happens because someone overtightens the terminal bolt and it creates micro cracks in the plastic casing around the terminal.

AGM's pretty much avoid this issue entirely due to the internal chemistry differences.
