12V Battery replacement with H4

[mr.Magoo]

Over time, going down to 50% or 40% before topping off will take its toll.
Going below 90% for 4 days is not a good thing for the battery.

Where do you find this information?

OK, so it's not a backup for the truck itself, it's a backup for my data logger / dash cam.
It's placed where the OEM jack used to be and I have a separate DC/DC charger to maintain it.

So someone DOES have their battery in the rear seat!

Did I miss a question at some point ?

I'm not using any of the Ford Aux / 2nd battery stuff, this is just something I cobbled together on my own.

No, my reference to the OP saying "rear seat" and my confusion thinking that they had their LVB in the rear seat of the vehicle. They were referring to the seat of the battery tray that that grabs the back of the battery before the hold-down is installed.
