Those who would like a decent summary of various kinds of batteries may take a look at Battery Chemistry. The page may be slow loading, as it's fairly large; but it's one of the best summaries I've found.
It may come in handy in the next thread about alternative power systems that don't generate a lot of chipmunk turds.
WYSIWYG knows that her batteries are good, although we don't know how she knows; and we're not told what devices don't work; so it's obvious (?) that what's wanted is sympathy, and not explanations. So "tisch, tisch" extended, I guess.
