12V battery empty/caputt must be originals or does it go unoriginal?

Hello dear Porsche fans, I am new here and hope for help! I have recently been in possession of a Porsche Taycan 4 Cross Turismo Bj. 2021 with slight front damage and unfortunately the airbags went up. The 12V battery is empty and cannot be charged according to the Porsche center, where I ask myself the question, if this is correct there is described in the operating instructions the possibility of a starting aid. Furthermore, PZ says that the battery can only be replaced with an ORIGINAL battery. , that car or tester can only recognize an original battery and only then further test or the activation of the HV battery can be performed. Since the car should be made ready to drive also the HV battery must be reactivated (due to the triggering of the airbags was deactivated). However, Porsche can not guarantee me if I buy an original new battery, which the Hv battery can be activated without airbags. Please answer if who like Erfa Thank you very much already.
