I'm not going to be using my ride for 3 weeks exactly and wanted to know if I should disconnect the battery on my 2007 350Z for those 21 days?... or leave it alone? and use a battery jump starter when I get back because for sure, I imagine it will have a hard time firing back up again or won't even start. I checked the stickies for long term storage but was wondering what notes can apply for just a short 3 week "storage" period, regarding the battery? Any info would be appreciated... thanks!

 

Disconnect if there is a drain or keep a tender on it.
