So I'm out in the woods a while back and go to make some noise with the AR. The EOTech blinks off with the first round. I finish the mag with the BUIS that were already up and check the batteries.
Yep, FQ's post some time ago came back into my head - the batteries leaked.
Apparently 2 years is too long of a wait to change them out.
There wasn't any real corrosion but the contacts were starting to change color. I cleaned it up with some vinegar, rinsed with some alcohol and buffed the contacts with some fine sandpaper.
I now have replaced the alkalines with some lithium batteries. Rumor has it that the lithiums will shrug off recoil better. Dunno, but at least they're new...and yes the sight works fine.
If you have batteries in your sight, check them NOW!!

Always heard that a good rule of thumb is change them every year on your birthday.

Unless it's a gun you use (and check) every day then this is a reason why battery powered gizmos aren't always a good idea.

Back in June of 1980 I was down in Florida to watch and film a Space Shuttle Launch. (The fourth one). I was using 35 MM cameras back then, and forgot and left the Duracell Alkaline batteries in the power winder. I forgot about them until just a couple of years ago when I took out my camera equipment. The batteries had swelled, but leaked very little. Just a bit of corrosion around the contacts which came right off with a pen erasure. I loaded it up with fresh batteries and it ran like a champ. It wouldn't have mattered though as 35 MM cameras are like 8-Track tapes and flashcubes. All but totally obsolete.
