Might be worth trying to find what discharged the battery, or just ensuring you completely disconnect it if leaving for a time. It's easy to get 12.9 volts on a batterry while charging, and find that voltage collapses to almost nothing when any load is present. Had that with a 70AH car battery which suddenly failed. Looked fine on charge but just turn the ignition on was enough to drop the volts to near 6.

Thanks. I will check both those tomorrow. I think the drain may be the starter solenoid. I cant remember but i think it measured some continuity between + terminal and earth, thats not right is it?

No, the solenoid should not conduct any current when not operated.
