Do you change your optic batteries out annually ?

Honestly it's not about the money; it's about the peace of mind. Yoni posted that he normally swaps his batteries out on December 31st every year, but had one fail 2 days prior. No harm, no foul. But what if it had failed at an inopportune time?

Most of us don't fill our cars up with 3/4 of a tank left, so why change batteries then? Nor should we wait 'til we're out of gas to use the 5 gallon container we've got stored in the trunk. The voltage testing is nothing more than a fuel gauge.

This thing is great just wish I got the one that reads CR2032s. I use it all the time.

So the new dual fuel (rechargable or 123A) lights from SureFire and Streamlight are pretty nice. Buy two batteries and you always have one in reserve, they typically are 1000 or 1500 lumens and really nice. Not small enough for most red dots yet but that is probably coming one day.

I have had the bigger model for over a decade and use it daily.

I once made my kid test a gallon bag of mostly used CR123s as a sort of lesson, it would have been me otherwise!

For my Aimpoints I replace on even numbered years. I know this to be acceptable as I left it on for over 5 years on my normal setting and it still worked, so every 2 years is adequate.

For PVS14, I just keep spares in my kit.

Jan 1 2022, replaced battery in my RMR. It was part of a battery pack that was like 2 years old, but they were rated for a long shelf life. Last night at midnight, the battery died.

This is a perfect example of why I check battery voltage on my batteries. A new CR2032 should be at 3.3 volts and dead at 2.7 volts.

Do you check with an analog meter or a high impedance digital meter? Just wondering if the digital pulls enough load to get an accurate reading? Often wonder if a Fluke SV255 added to a digital meter would give a more accurate reading. I might try this later today and share the results.

"Carry Guns" batteries are changed on Bday. "Range Guns" changed as needed.

I do use a digital meter, though I'm not sure if it loads the battery. I doubt that it does, but I'll take a look at it and report back.
