dustyrob456, Possibly faulty battery/connection, weak charger or perhaps loose/dirty or damaged charge port. Look in the charge port and blow/pick out(carefully) any dust/debri that may be causing an issue also look in the port for any bent pins and straighten very carefully with a tooth pick. Try a different compatible charger/cord to see if that is the issue. If different compatible charger/cord does not fix and port looks/test good, the battery or connection could be bad, if able to clean battery connection(Qtip dampened with 90%+ Isopropyl Alcohol) and reconnect/install battery, still not charging battery probably faulty. Below is a guide that will get you access to battery, connections and enable you to check for other possible loose/bad connections and components. Good luck.
