As far as I remember the Chinese battery makers started doing cheap copies of known brands but because they were constantly looking for new ways to improve profitability and weren't being regulated by more strict european or american labor laws, soon developed better and better production methods while increasing the quality of their products and soon found themselves selling to some of the larger European car manufactorer.
I will see if I can dig up the story it's been a while and was in some radio program.
