Their internal resistance is far too high. By the way, the TCH's absorptive-glass-mat type of 12-V battery does not have a high peak current rating, and so should never be used for jump starting another car.

I can't find any data on what the absolute maximum amperage a alkaline cell can produce at a reasonable voltage.
What if I take my 12 volt battery pack (made of of D cells) and attach it to the dead 12 volt battery. Let the battery pack dump itself into the dead battery to it's own self depletion. I "suspect" there is a good chance the 12 volt battery would now have enough capacity and amperage to start the car. Assuming the 12 volt battery is only discharged and not defective.
In effect I use my battery pack to "charge" the 12 volt battery and not directly power the TCH computer and inverter.
