Here is a quick how to video on changing the 1632 Battery in your Sig Sauer ROMEO ZERO Optic. I take the optic off of my Sig P365XL and quickly swap the battery to a new fresh battery. The process is pretty straight forward and just requires a 2mm Allen Wrench (or you can get by with a 5/64″ wrench).
