Red Dot shorting out on slide?

Hey, I'll ask this question of this collection of greater minds. :)

Anyone have the experience of their red dot appearing to short out on their slide? I can't think of any other explanation for what I am experiencing. Installed the optic (Vortex Viper with the battery in the bottom of the optics). It worked for 3 rounds and then lost the dot. The Optic works if I load the battery and hold it in place between thumb and index finger. When I install it on the slide it doesn't work. Take it off, it works, install it and it doesn't. I put a strip of electrical tape on the bottom of the optic between the optics and the adapter plate and it now works on the slide. I have to wonder how permanent this "fix" is going to be. Am I missing something else?
 
When I was researching red dots I came across one type that had a battery compartment issue but I think that was an older Burris, not a Vortex but I might be wrong. The fix was the manufacturer sent you a new battery cap.
 
Sounds like the battery terminals need to be bent out, to contact the battery better.

I had a shield RMS, and it did that one day. I thought it was the battery, but nope.. Just the connections got bent, that it lost connection.
 
May sound obvious but make sure your mounting screws are properly torqued down...pressure from the mounting screws maintains the battery contact and sometimes they work loose if not torqued all the way down and loctited.
 
Thanks for the replies.

Make sure the battery is a cr1632.

Viper takes a 2032. First thinking it was a battery problem I also switched out the one that came with the optic with a new one I had at hand. Same problem with both.

I suspected the same thing and checked the terminals. Both bottom and side terminals are clean and are making good contact.

When it started working with the strip of electrical tape in place I reinstalled the mounting screws very tight and loctited them in place.
 
I had the same problem. Installed the base insulator piece [ same dimensions as optic ] this cured the problem. The tape is doing the same thing.

Is it something you got from Vortex? I've not heard of a base insulator piece. (Maybe it's common and I'll do some research.)
I shot about 120 rounds yesterday testing the tape solution and zeroing the optic and it worked fine. Fingers crossed.
