Hi,
Based on your description, the battery has failed. Although it is charged, it can't handle the load that is placed on it. What I recommend confirming this theory is to charge it and take it to a parts store to have it load tested. Most parts stores will do this free of charge.
You could try this simple load test at home as well.
