I just put a simple electrical system in my cargo trailer. I have two AGM 12 volt batteries. The positive lead goes through a disconnect before connecting to the inverter. I fully charged the batteries to 100% and left them with the disconnect off. It shouldn’t matter but the inverter was off too. In one week the batteries dropped to 53% just sitting. Everything is mounted to a wood shelving system I built. Is this normal? I can do a test by fully charging and removing the battery cable to the disconnect. I don’t think it will matter as the only thing on the system is the inverter and it was off.
any ideas? Thanks
