Your battery is just fine. If you are not going to leave it on a trickle charger you will need a battery disconnect switch.
Internal battery resistance alone will discharge a battery. Add 1.2 amps for the Propane detector, the overhead ("off" voltage draw) of your Concertone radio and 12 volt side "off" power of your fridge, I am surprised it lasted 10 days.
