Read years ago it was good to cycle the battery rather than just let it sit.

I'd check with your battery manufacturer on that. Batteries,
especially starting batteries, are only good for limited amounts of
cycling. More common is to leave them at their so called "float"
voltage (usually about 13.2 volts). A battery in good condition
however needs very little attention if stored fully charged.
