You should take the laptop, battery and charger to your local computer repair shop and allow them to check the equipment out. They can determine real easily if it's the battery that's bad, or the charger isn't charging the battery, or if both of those are okay, but the connection plug inside the computer is bad and needs to be replaced or just re-soldered.
