An RDS without a battery is just a piece of glass to look through.
Yep. I'm not worried about the sight failing. The battery being drained is another question.
The flip side of that with the T1/T2, H1/H2, and I think
the Primary Arms Micro RDS, is that the battery is good for 50,000 hours, or 5.7 years. If you keep a stock of CR2032 batteries on hand, you’ll have a usable RDS for many years, so long as you can replace the battery. I always have 5 or 6 of those on hand in my safe anyway, because I’ve got 7 different optics that use that battery. But, if everything ever goes to heck, those batteries may no longer be available. If you have an etched reticle, you still have a functioning optic. In fact, it’s one of the things I really like about my 4x32 BAC ACOG - it has an etched reticle AND dual source illumination. If everything goes to heck, and I can no longer have Trijicon replace the tritium, I still have an fiber-optic illuminated reticle as long as there is a trace of ambient light, and I still have an etched reticle even if there is no illumination at all.
RDS’s work great, but only if you have access to replacement batteries when yours eventually runs down ... as they all do.
