The CTEK MULTI US 7002 12-Volt Universal Battery Charger # CTEK56353 referenced in your question is a multi stage fully automatic charger. When leaving the charger on your vehicle battery for months at a time (which is perfectly fine to do with this particular unit), you will just want to have the charger in the "NORMAL" mode.

The "NORMAL" mode will automatically cycle through various phases when first connected, which will eventually fully charge the battery. Once the battery has been fully charged, it will automatically switch to maintenance charging. When in this state, the battery will receive a pulse only when the voltage sinks, keeping the battery in good shape when it is not being used. It can remain in this state for months at a time, like what you are planning to do.

This is a fantastic battery charger for exactly this reason and it will work very well for your specific application. I have attached a short video demonstration along with the written user's manual on this product that you can also take a look at.

The CTEK MULTI US 7002 12-Volt Universal Battery Charger # CTEK56353 isn't designed specifically for your desires so I'm honestly not sure what setting will be best. You will want to check your Mac Mini transformer for the amperage to determine the closest option. I can't imagine you wouldn't run it in recondition mode basically giving the 1.5 amp charge, but without knowing all the connections and your specific needs, I can't really give educated counsel.

In order to use the Recond mode you just need to select it by pressing the "MODE" button and stepping forward one press at a time until you get to Recond. The battery should be fully charged first using Normal model before switching over to Recond. Recond is used to recondition a severely discharged battery.
