Anyone done it?
Just curious if anyone has resorted to drastic measures yet to address battery issues.

Dual 12v batteries in parallel?

If you dont have room for one big one, two in parallel isn't a bad way to go. But if one goes bad, it will suck the life out of the other one.
So if you were going to install two, you might consider just keeping one on standby and have a way to cut over to it.
Unless you needed long unattended or uninterrupted battery run time with the engine off, or you had a current (amps) deficiency, a parallel arrangement doesn't buy you much except the ability to charge both.
But there are other ways to keep the standby topped off, a small trickle solar charger perhaps or even a smart dc-dc trickle charger powered by the main battery, that will cut off if the main (supply) voltage drops below a set threshold.
Just spitballing. But if you are worried about the bad cells we have heard of in some Ford batteries, then the worst thing to do is strap such a battery in parallel to what may be a defect free battery

If you’re going to have to make room to make it fit anyway, why not just go with one much larger 48H6 AGM battery like many Escape Hybrid owners have done, which by all accounts seems to clear up almost all issues pertaining to low 12V SoC?
2021 Escape manual even lists that battery for replacements although 2022 regressed to the tiny 99RT4.

Definitely good thoughts here. Probably the only good way to do it is two new batteries from the same production batch and toss the stock. Hoping I never need to consider it. I like the cut over approach better too.

This seems like a good idea. I'm curious why the manual specifies an AGM for the EB but not the hybrid though. I noticed that AutoZone says AGMs require specialized chargers - maybe that's why? I'd be a little concerned about installing one if the hybrid doesn't have the necessary equipment on board to keep it healthy.

Interesting. Lots of 2022 Ecoboost units were not AGM. Mine wasn't and neither was the replacement.This seems like a good idea.

availability would be my guess.
in your earlier reply you mentioned using a larger battery in a hybrid. I don't have a hybrid but I've seen the battery box. can you really use a larger battery without cutting plastic or metal?
