So is my Kia EV6 12v battery fixed? Also what i think caused it & how to avoid the problem in future

So is my Kia EV6 12v battery fixed? Also what i think caused it & how to avoid the problem in future.

Since all of my 12v problems started after i had the update done at the dealers for battery pre-conditioning and also drivers door control unit replaced i wondered if havings the boot/door/tailgate open for 2 hours could have a triggered the problem?

Also what was the impact of leaving my Motorola MA1 AA adapter plugged in?

Is the VCMS (Vehicle Charging Management System) kicking in to charge the 12v battery when it takes a dip?

All these and other questions answered.

I used a Quicklynx 2 battery monitor to help figure out what was going on.
