Letter Re: Red Dot Sight Battery Longevity
JWR, I have a red dot sight battery, lithium Energizer CR2032, which was stored in it’s original packaging in a refrigerator since May 1996, almost 13 years ago. I recently opened it and have been testing to see if it would still work, at present I have about 11 hours of use on it. I know this is anecdotal, but the point is, if you use red dot aiming devices and it uses one of these type batteries, it is probably worthwhile to store a good supply of batteries for long term use.
