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.

In other words if the resistance is constant and the voltage is lowered then the amperage is also lowered.
