What I do know is a green LED will last twenty hours, as apposed to twelve hours with a white LED, with a pair of CR2016 batteries.

Both the CR2016 and CR2032 are rated as having a battery voltage of 3V. The CR2016 being half the thickness of a CR2032, also stored less energy.

Stacking 2 CR2016 together does not increased the amount of energy, it only double the battery voltage to 6V.

Hence using 2 CR2016, would produce a brighter light with no increase in the runitme. Using 1 CR2032, you will get a dimmer light but longer runtime.

Hope it help.
