Yes, batteries are pretty uneven these days, I seem to have bad luck with them in general but once in awhile I get a good one that keeps going and going.....
I find that things made in Taiwan are pretty good in general, products from the Peoples Republic not so much. I'm sure they can produce good stuff, they have a fairly good space program. When companies ask them to make stuff, if they are looking at maximum profit, quality suffers every time.
