A 12V battery loses 1% of its charge per day. So, 30 days=30% loss, 60 days=60% loss. Those "Brand New Batteries" sit on the shelf for months at a time. Charge it.

SPARK PLUG thats what i draw my conclusion to if not you need to get it looked at maybe you blew your starter

A "New" battery right off the shelf MAY not hold a full charge, and MAY not have the amps needed to turn a starter. Get a battery charger and let the battery charge for 6-12 hours before you try it again.

More information about what happens when you try to start.....Lights working does not equate to a battery that is capbable of turning a starter. It takes many time more amps to run the starter than the lights.
