December 12th of 2014 I did a battery test using two Maglite AA mini-mag with incandescent bulbs. I'd forgotten all about that test and the original thread on BLF that I posted them in until this morning. I got an email notification saying a new post had been made. So I'm re-posting the results here.

Sunbeam Heavy Duty (Dollar Store non-alkaline)
Continuous run time: 2:10 (dim at 1:30) 15 cents per battery normal price ($3 for 20)

CVS Brand Alkaline
Continuous run time: 4:58 (dim at 4:20) 49 cents per battery normal price ($11.79 for 24). BOGO brings it down to 25 cents per battery.

Harbor Freight & Tools Thunderbolt Alkaline
Continuous run time: 5:00 (dim at 4:50) 25 cents per battery normal price ($5.99 for 24). Sale price for this test ($4.29) brings it to 18 cents per battery.

Duracell Alkaline
Continuous run time: 5:20 (dim at 4:50). 42 cents per battery based on Walmart price of $9.97 per 24.

The prices may not be the same 7 years later. :D

Little surprised as it ran over 5 1/2 hours and was still dim but on when I had to leave.
