From the description it sounds like you allow the battery to discharge flat dead while not in use. Now the battery is shot.
You will need to replace the battery and keep it charged.
I will 2nd that opinion.. There is a SLIM chance the battery may recover but batteres fall into 3 groups.
Starting: Stick a plastic fork in it.. it's done
MARINE/deep cycle (most 12 volt packages) slight chance of recovery
DEEP CYCLE (usually Gc-2 6volt paired) Better but still not good chance of recovery.
I appear to have gotten lucky in that I ran some down and let 'em sit that way for about a month (or 2) and when I applied the charger it SUGGESTED they sucked up right close to their rating.. however this is no longer in RV service and if the batteries are good for 10% of their rating I'm happy.
