Are my rechargeable Energizer batteries dead?

I hadn't used these AA Lithium batteries in my camera for a while (for about 5 months), and today I wanted to put them in the camera, but it didn't turn on. So I figured I should charge them, but then the charger turned off after a short while. I remembered my dad's bought a digital battery tester, so I used it to read off the voltage - two batteries were 1,63V, one was 1,69, and the last one was 1,74. I think I used them with non-rechargeable batteries, that's why the voltages differred. I wanted to check if any would work with 3 rechargeable Eneloop batteries. Those of 1,63 and the one of 1,74V wouldn't work, and the one of 1,69V would. Does that mean that this one is ok, and the other three are dead? Are they overcharged? How is it then that the one that is charged more (1,69V) works, and those that are charged less don't?
