NAPA brand. Quick pickup at store and swap out. No need to over think this. Reset the BCM if applicable . The sequence is in the manual or easily searchable here.

Another OEM battery.
Was going to go with Optima Red Top but I liked $180 vs $600.
The OEM's aren't great but I suppose they get the job done.

This has been discussed heavily. You have 2 options, go generic low quality like diehard, napa, Walmart etc (just never buy a interstate battery they barely last 6 months).

Or as many of us do for mustang you can go high quality and get an xs power d4700. It's slightly taller than OEM (fits under the hood just fine and can still use the battery cover. The cable just won't sit inside the cutouts but it is a non issue. Battery will last significantly longer and is stronger so it starts better and can power the radio and accessories more. The OEM battery literally says (not for use with ANY accessories) aka if you have subs or lights or anything the battery isn't designed for it.

Optima truck battery of some sort (I think 96L), relocated to the trunk. The mag ride and BMS sometimes does not play nicely with the LiPo's. Especially if you have the magride tuned. I know a lot of guys who had issues with any LiPo, as I did. I probably know just as many who never had an issue. So it's just sort of hit or miss.

Just an FYI in case you don't want to risk all that money only to have it not work.
