I typically use alkaline cells in my smaller unit and a set lasts a couple of months even under frequent use. I use two. One is a 20mW that looks like a typical green laser pointer but is much brighter, the other is a 100mW unit (tested at 112mW) that never seems to have cold issues. It uses a CR123 battery however, not AA cells. It is visually two to three times the brightness of the 20mW unit. On Sat, Jan 19, 2013 at 9:57 PM, Josh <mountaindrifter@gmail.com> wrote:
I think performance in cold temperatures is more an issue with the batteries.
