hi bill, i'd imagine the battery is completely knackered & even though you charged it up it's probably not holding the charge. batteries need recharging especially small moped type batteries even if they're not being used & after several months of non use the battery will have sulphated & died. stick a new battery into the ped & it should be ok. before you try & start it put in a new spark plug, i would also advise that you drain the old fuel from the tank & the carb & put fresh juice in. petrol goes off so you might find it hard to start the bike.
