stereo. the "off" position is really only standby. however, it should take 4-5 days to drain a single 12V battery. drain is not insignificant.

most keystones built after about 2013 have a external battery disconnect switch. check to see if your does.

also, the standard WFCO charger is not likely to fully charge a single battery discharged to less than 50% in 24hours, more like 48 hours. virtually impossible to get them into the boost mode with 55A output, instead it will default to 13.2V and 10A or so tapering down.
