I just went out and checked my AGMs which have been on 13.7 since last evening after getting 70AH back in from being 80AH down. Say 94% SOC at the time. That's when I dropped the voltage to 13.7 from 15ish.
Are you sure that 13.7 is the correct float Voltage. My MS TS 45 PWM is floating my AGMs right now at 13.87V. The battery temperature is 41F.
I just checked weather.com and see Victoria is 35F and rain. Is your AGM warmer than 35F.
