Im looking into a new optic for my next build, and like the eotech, but am leaning towards the aimpoint pro for its much better battery life. I'd prefer to use an optic that uses AA's, but the aimpoints that do are monitarily out of reach for me. Just exactly how long will a 3v DL1/3N battery last in storage? I'd hate to buy a bunch of spares only to have a bunch of spares all go dead in a couple years all at once. I have a battery charger that can plug in the wall as well as charging with solar, but doesnt charge the smaller 3v DL1/3N's. Im wanting the ability to charge them up even with no power.
Supposed to have a 10 yr shelf life before they drop 10% iirc.
I may be wrong on that exact number but they have a decent shelf life.
IIRC most batteries have a 10 year shelf life. So it really doesn't matter. I do prefer AA than anything else and I feel much more produced than any other battery so I ended up with a CompM4s
