Mercedes-Benz SL55 AMG: I would like to recharge my both batteries,

This answer was rated:

I would like to recharge my both batteries, under the bonnet and in the trunk.
The question, the bonnet is open as my trunk and if I lock my car the alarm will go off, do I have to keep it unlocked.

if you do not want to keep the car unlocked you can disconnect both battery's and then lock the doors and just charge the battery's with the battery cables disconnected off the 2 batteries

as then the alarm will not sound with the hood and trunk open with the car locked
