Agree with Tennis. Sounds like a loose cable or a bad ground. As well as checking at the battery check where the ground cable attaches to the car to be sure it isn't loose or corroded. If nothing there have the battery load tested. Might be time for a new one.
Agree with the other answers but, typically, just hooking a charger to the battery does not supply the current needed to start the car. Did it fully charge the battery before you tried to start the car? I think your battery may need replacement.
