If you have dormant cars, keep the batteries charged, otherwise they will go dead cell, necessitating replacement.
And with the propensity of modernz for parasitic drain, even disconnecting the battery is better than doing nothing. I have a (very useful) Chrysler Grand Voyager that loves to kill its battery over a few weeks of no use. And when the battery starts to get low, the infinite wisdom* of GM design guarantees both to completely kill the battery AND invite all sorts of security issues. How?
By randomly opening and closing the power tailgate, until the battery is dead. Ask me how I know...
