I got a 5mW (class 3A), 650nm laser pointer yesterday and it came with 3 AG-3 button cells and over a day, it was on for about 60 seconds, maybe more however I noticed the beam wasn't as bright as it was when I first put it on. Over 30 seconds worth of use, it seemed to dim further until I replaced the batteries with some AG-3s that came with another product and it was noticably brighter. The 3mm white LED wasn't affected.
The website I ordered it from said its battery duration was 3 hours (it's the 2 in 1 at the bottom). It also said it came with 3 2.5v watch batteries (I thought AG-3 cells were 1.5 volts).
Why did the button cells lose their power so quickly?
Why do the AG-3s cause the laser beam to dim instead of allowing it to be at a constant intensity?
Did the website get the facts wrong?
Thanks for any replies
