The website posted below is one that I found to try and determine how long I could run two - three double A batteries in a series to light a white LED with a resister. I've got them hooked up to a voltage source of 3.66V and they are drawing 0.09 - 0.10 amps last I checked with my fluke meter.
So..
The battery life of AA batteries (alkaline) seems to be around 1800-2600 mAh.
Using the mid range of 2200mAh and my constant amp draw of 0.10 amperes the calculator tells me I'll get about 27.8 hours before it's 80% drained. I suppose I'd have to use at least 3 AA batteries in order to get closer to full drainage because two AA at 1.5V =3V, the minimum I'd need.
I also used 1.2 for Peukert's number because that website said that is the average.

Please help me check what I've done and verify if that information I got is within an acceptable range for approximation.
Thanks to anyone taking the time to read this.
