I took delivery from Sport Optics on the above scope at the end of March. The CR2032 in the scope was DOA. Replaced it with the spare that was included and the scope and the illuminated reticle worked. Yesterday I tried to use the illuminated reticle again. The 2nd battery was dead again. Replaced the 2nd one with a new Duracell Lithium CR2032 Lithium battery I just bought. Has anyone had the same problem with the supplied batteries or am I eventually going have to send it to Vortex if the Lithium battery also dies if this has been a problem in the past?
