So far I haven't found one I can actually recommend, as all of the ones I've used that are made for charging individual-type cells (AA, AAA) have either damaged cells (possibly by parallel charging them; never opened them up to check, but I am going to now), or the chargers failed and stopped recognizing batteries at all.
This includes one by Sony, two by Olympus (for their old AA-based cameras), two generics, one Ray-O-Vac, one Realistic, and a few others I don't remember the names of (that I dont' have anymore).
I have tried using a Tenergy NiXX charger that's for 7.2V-12V packs to do charging of some of my AA and AAA flashlight batteries, and it appears to do ok most of the time, but I usually have to discharge some fo the cells manually beforehand so they match voltages (although probably not SoC), so that they all charge more or less correctly together. I have to put the cells next to the temperature sensor as that charger terminates charge partly by Delta-T, I think. I'll have to dig out that charger to get it's model.
I have also tried charging some on the Accucel6, witout a thermal sensor, and it appears to correctly terminate charge via delta-V, but I have not extensively tested it.
I tried testing using the Venom, but it wouldnt' start charge without the thermal sensor, and I didn't have one at the time and never went back to try again.
