>It's a lithium coin cell, I doubt there's huge variance like this. Anecdotally, from my own experience, the differences are real and huge. The no-name CR 2032 cell I bought from the discount store lasted 3-6 months in my room thermometer, while the name brand one closer to 2 years. >seems to be enough of a margin to call it a racket I'm not trying to justify the racket pricing, I'm just saying the differences between those no-name Chinese batteries you can find in 1 euro LED candles and good cells from a reputable brand is real and palpable.
