My problem is the following: the battery (2007 Cayman 2.7) is flat and therefore I cannot open the front booth in order to charge the battery. This catch-22 can be solved by connecting the fuse with start cables to another battery and then opening the front booth.

Since I have no other battery my question is:

Can I connect the fuse in question to my battery charger and get sufficient current to open the booth or will I be doing damage to the electric system?

PLEASE HELP as soon as possible... Thank you!!!
