I get the impression that a lot of what people describe as memory
problems are really just out and out battery damage due to
overheating and probably other stuff. I use a charger that shuts off
if the batteries get above a certain temperature and I've noticed
that there may be somewhat less of a tendency for this to happen if
the batteries are fully discharged before a charge. The charging
behavior of older NiMH batteries does seem to be rather variable, and
I don't keep close enough track of my sets of batteries to be real
sure of what's going on with them. I have had several sets, roughly
the same age, stop holding a charge all at about the same time. So
far I've dealt with this by just tossing everything that seemed
questionable and getting new ones. You don't have to get very many
cycles out of them before they are cheaper than disposables.
Has anyone used lithiums much with the istD or Ds? I know there's
been some speculation that the higher voltage of lithiums makes them
last longer than higher capacity but lower voltage nickel batteries.
Getting 150 shots out of alkalines really has me wondering if they
same might be the case with my Pentax.

I charge my nimh batteries if I suspect they're low, and I'm going
to shoot. They dont' have a memory problem like nicads. I don't
think it's necessary to discharge them fully.
