It would be very informative to know Voltage readings BEFORE charging as that would help with confirming a 25 SOC%.
Many of us run our own tests with adequate metering to prove that our multiple chargers are cooperating. E.g., what were the charging Amps when the charger light indicated full charge? Also, after! I have observed my automatic charger charging after the light comes on. One useful measure of full charge is when Amps stop decreasing for an hour. That rate could be a good indication of a constant load.
This is most likely one of those mysteries that is most easily solved by taking the batteries out for professional testing.
I don't see any way to use this proxying to get anywhere soon.
My definition of marine is a battery that has been hardened for rough use. It does not mean deep cycle.
