Storing a full corny keg

I have 6 corny kegs in my kegerator fridge pretty much full I’m wanting to brew
Again I brew 10 gal batches so when I’m ready to keg can I store them in my basement
Which temp ranges any where from 67-70 during summer also how long can I store them
And they will b stored with out C-02 as my tank is in the fridge thanks

Keg them, purge with CO2, seal lid and store at room temp for a month or so with no problems at all. Of course that varies by type of beer. The bigger the beer, the better it ages.
