509T battery life
For a while, I have thought the 509T to be the best available all around carry optic for me. Sealed emitter, the flat back doesn’t accumulate debris like an ash tray, clear lens, largish display, good controls, and carries similar to an RMR size wise. My question has been battery life, ever since the Acro made me question battery endurance.
I turned a 509T on manual, a click or two down from high intensity, and have left it running since early October. Headed on a trip, I decided to pull the battery and test it this afternoon. It was the Panasonic 1632 it came with. It shows 80 percent full, so that is endurance I can easily live with, as it should last a year at the rate it is going. I replaced it with a new Duracell.
