I think I've lost my instructions to the Ctek. If, as you say, this is possibly a battery that died in spite of being on the maintainer, is it typical for the Ctek to indicate fully charged ("green")?
Again, yes the Ctek (or any other maintainer) will show full voltage indication because the battery is at full voltage, but the battery's ability to generate amperage (which is what turns the engine over) is low. A maintainer has no way to measure reserve amperage in the battery, that requires a load test.

There is nothing wrong the the Ctek, but the battery is probably toast, unless your amperage problem is cable related.
