True, but the thing is, the battery in that 1 euro candle was most likely not a name brand one with a long life, like a Varta, Panasonic, Duracell or Energizer, but a no-name one that won't last very long.

That's what they said at the store when I complained about the pricing, but I doubt it. It's a lithium coin cell, I doubt there's huge variance like this. I searched the internet a bit for capacity measurements of cheap coin cells, and the only thing I found is [1], which shows that the discharge curve of a cheap coin cell was almost exactly the same as the one from the data sheet of a name brand cell. Also, a comment on the page [2] says that name brand cells cost 25c when buying 100s, so a price of 7€ for 2 seems to be enough of a margin to call it a racket.

  >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.

    OK, so that's one anecdote saying there's a difference, and one anecdote saying they are the same. Would be sweet if someone bought a couple of different CR2032 cells and tested them.

I'm not convinced the branded ones last any longer. Typically they don't even quote their capacity.
