Thanks for the comparison. I think there is a slight slip in your math.

It seems that this should be 500 cycles per rechargeable (40?).

That would be 500 alkys for each rechargeable bought. That massively tips the scale in favor of the rechargeable.

Inspired by your calculation I did some research and calculation of my own. I found that I could get 1900mAh Eneloops around 2€ a piece (shipping and taxes included) rated for 2100 cycles and Alkalines with compareable capacity for 0.25€ a piece when bought in bulk. The cost for electricity to put in the Eneloop would be around 3€ over the life time allowing for low charger effectivity.
That makes 525€ in alkalines or between 5€(2100 cycles) and 11€(500 cycles) in rechargeables for those 2100 cycles.
With Eneloops it almost makes sense using them in extremely low drain devices like electronic clocks.
