One thing missing is that todays vehicle need more than 12 volts,if you check you altenator output i's more than 12 volts. I have used both in my years of experience a 9 volt and a 12 volt jump pack a per manufacturers instructions and guess what never an issue. With todays vehicles you can run into many issues when you remove all power from memory. Forget radio presets not really an issue,how about driveability relearns,readiness for inspection just to name a couple. IMHO,we're over complicating a simple task.
