Drove the car home night before last and shut it off. Went out to start it yesterday and there is no power. As if battery is dead. Put battery on charger, says fully charged. No lights, no starter, nothing.
A bad cell could have too much internal resistance when the battery has to draw many amps to turn starter over. Put headlights on then hit the starter, if the headlights go off, the battery is bad or a connection at the battery cable or ground cable is dirty.
If you have a voltmeter, attach to battery and notice voltage of ~12v or greater, then hit starter, if battery is bad, the voltage will go from ~12v to under 9v and result is starter won't turn over the engine.
