I checked the battery connections and they look tight. I can tighten some more. I also tried to jump-start using a DieHard jumpstarter battery but the same outcome. Although I am not sure maybe the DieHard needs to be charged. I don't think I've re-charged it since I bought it 2 years ago and have used it 2-3 times on my Land Rover and John Deere riding lawnmower.
