So I bought a Deltran battery tender as I got back from a vacation and my car hadent been started in 1.5 weeks and I came home to an almost dead battery as my clock was zeroed out and my date said 12-28-13 (arrived 1-3-14).

My question: I fully charged my battery (green light) and had to disconnect the tender so I could pull my car out of the garage to put up the Christmas tree and pull my car right back in (15 mins) upon pulling it back in I put my car back on the tender and its been back on the charging (red light) for 2 hours now. Is this an indication that my battery may be shot?
