Pro Battery Life
The battery life on all of our optics are rated at a certain setting (on the PRO it’s setting 7 of 10; off being setting 1); at room temperature and with a quality battery.
There could be many different reasons why the battery only lasted 6 months:
-It could have been left on max brightness for an extended period of time (ie. weeks),
-The battery received from the manufacturer may not have been at a full charge, or
-The temperature at which the optic was stored was too extreme.
