...you have the batt mAh, and the working voltage and the flashlight mA draw?????
Case 1. Li-Ion cells...
I am making a guess...a protected batt will work from 3.6-4.2V. that means a drop of voltage which when multiplied with the current draw will give us watts...compare that with the batt amphours and you have runtime hours.
Case 2 Li primary cells.
Now I am troubled, cos from a voltage value and below that the driver will drop out of regulation. But if you know what voltage is this (both nominal and working batt voltage under load), then you can measure the regulated runtime with the case 1 method...
am I correct????
