The A23 battery is rated at 55mAh. Your draw is 430mA. That's much more than this small battery can handle - it will die in about 7 minutes.
I wasn't able to quickly locate internal resistance data for A23. That said, this battery is composed of a stack of small 1.5V coin cells internally; supplying 430mA is going to make the cell heat up, further reducing its life.
MORE: You clarified your run-time requirement, which we now understand to be up to 3 days, so (at least) 31Ah. That's a much larger class of power than even the largest common primary batteries. It will not be economical, let alone feasible, to use them. You should consider a rechargeable (secondary) battery instead, be it a sealed lead-acid, AGM, LiFePO4 pack, or similar.
There exists a possible off-the-shelf solution: use a 'power bank' type of product. Some even have 12V output capability, like this one: https://www.xtpower.de/Power-Bank-MP-50000
Speaking of which, if you have a bit of flexibility in your design at this stage, you can choose to leverage USB type C power delivery, which supports 5,9,15 or 20V. This would allow you to leverage the ever-increasing ecosystem of USB-C power solutions, including power banks and other secondary battery solutions (some of which even include solar charging.)
