Short of Normal Draining?
I've noticed that my charge controller is blinking every morning, indicating that the battery is charging, or in need of some charge, even though the controller light indicates a full charge the night before. Is it natural for an AGM battery to drain a bit at night, or is this an indication that I have a short, or does my controller consume enough from the battery each night that its consumption is what is causing the light to blink? The AC power is switched off and there are no DC circuits within the trailer (clock, timing, etc.) that that is not switched to OFF.
