Well said Gerald. The amperage, Jeff, will crawl quickly up at first and then slowly decrease as the inverter’s charger goes from Bulk Charge, to Absorb, to Float. But it can vary with what’s on in the coach, as Gerald noted, and on our rig that’s similar to yours, the voltage settles in around 13.4 in Float mode. So you’re just fine. One indicator of one or more aged/bad coach batteries is Float mode voltage lower than that.
