If I wanted to monitor a marine battery with an analog voltmeter I have laying around, could I assume that once the battery drops equal to, or below 12V... that would mean it is discharged and ready for recharge? All equipment is 12V same as car batteries that are usually above 13V. I just want to avoid buying a special gauge. I was pretty sure that that at 12V or below means battery discharged. Anyone back me up
