My fear is unhooking the battery removes all voltage to the entire system
Then when reconnecting it the surge of power goes to all the sensitive components and with the SKREEM module as vulnerable as it is to fail and without a source currently to replace it I fear disconnecting the battery if I don't need to.
I'm not really sure what the best answer is but I've stored my Crossfire every winter for 12 years with the battery connected and the battery tender also connected
