Well it does have an accessory position but I advanced it to on because accessory didn't offer the option of any kind of fan.



So another question I am researching is the OEM battery's reserve capacity. I'm seeing Subaru owners saying the OEM batteries are garbage in that sense and also in terms of cold cranking amps (odd for cars marketed as snow beasts) that have a CCA rating under 400. I'm having a hard time finding the specs on mine, Subaru parts websites don't say and I can't see what it is when I pop the hood.



I'm thinking I need an upgrade, especially with the multiple complaints I'm finding about lackluster power ratings of Subaru OEM batteries.


I have noticed the installed OEM battery looked small and is about 1/5th smaller than the size of the battery tray.
