I have to agree with Marty....Bad battery. Probably a dead cell and once that happens your done, get another battery. My experience has been once an automotive battery goes completly dead, nine times out of ten that battery will never preform like its supposed to if at all, regardless of the age. I sold interstate batteries for years and have seen this time and time again with week old or less batteries. If you have a battery on something that isnt used often and will sit idle for a couple months at a time you need to charge it at least once a month to keep the battery active.
