Unfortunately, no. Their experimental processes are not detailed in any 
way in the article (whether online or in print). I too was curious about 
the sample size, with such a variability in results! I agree, there is 
room for question, but I would expect (perhaps it's just a hope) that 
after all this time, CU would have their experimental methods together. 
I've never been impressed at their ability to provide detailed data 
(relative scales they use are a poor representation when measuring, say, 
an FM tuner's selectivity).

That said, perhaps I've provided no answer at all. Maybe the best 
practice is to just look for the best warranty, and be sure to pay 
enough for that battery! Not very scientific, but my empirical data 
shows that typically provides good results.
