Ours used to do this and it was a ropey battery. I was told that Optimax's need a tip-top-condition battery. We got a new one. Seems fine now.

Before, even charging up the old battery wouldn't fire it up.

Try swapping in a new battery?

Check your kill cord connection 1st.

thanks for the replies folks, the kill cord sounds good, as the battery is new but stereo was left on, on the last outing, and i charged the battery for about 30 hrs, so it should have had enough charge to fire the engine up, will check it tomorrow.

If it's a non-deep cycle battery, running it down (or letting it self-discharge) may very well kill it (or at least damage it to the point that your engine won't play nice with it anymore.)

Keep a smart trickle charger on the thing if you're leaving it sitting for long periods of time.

As I recall, starting batteries should not be discharged to less than 70% rated voltage; hybrids about 50%; deep cycles should survive discharges to about 25% without harm. None of them should be left in a discharged state for very long to avoid sulfation problems.
