Yes. With it sitting there not used, just the frig and monitors running it will be normal to use about 2 amps of power. So 2 x 24 hours a day = 48 amp HOURS. 48 AH X 12 days = 576 AH. Your two 12 volt batteries are about 90 to 100 AH with the ability to supply about HALF those ah for you to use. So you had 100 ah of batteries to provide this demand. Dead as a door nail and will fail soon if you keep doing that. The batteries need to be kept above 12 volts as a rule of thumb. Get a cheap digital volt meter and mount it where it's easy to see and stay above 12 volts. That may mean plugging in, running the tow vehicle,running a gen or solar. If you then keep doing partial charges the batteries will still fail in less time. If they are wet batteries keep an eye on the water level.
