The chemistry of the battery dictates how it should be cared for.
sulfating?? Using a lead unit in an EV seems foolish to me, but at least then it should be super easy and cheap to replace.
Only a precise capacity test reveals State of Health, ESIR requires comparing the current state to known-good "new" condition.
The 12V unit should be routinely getting charged enough to handle parasitic loads, even if the EV is in storage. For lead, it takes 5+ hours to get back to a Full state required for battery health - regardless of size. None of those issues with a LI battery.
As to the Ah capacity required, that will vary from one EV to the next depending on many factors.
I would think when an EV is in storage unattended, all the batteries should be isolated from any parasitic draws.
This would mean running a "recommissioning startup" checklisted protocol to bring it back online.
