You do you, but pretty much the entire 19 year span from the beginning GWOT until now has proven the reliability of modern red dots. And since the RMR, there have been equally long-lasting battery and reliable pistol red dots that have been tested in brutal and extreme situations.Personally, I wouldn't trust my life to batteries. In my experience they will fail just when you need them most. I'd stick with iron sights on my personal carry or duty gun.
I think it’s more a fear purely based on not having enough experience and exposure to red dots. That said, a simple solution is to use suppressor height sights as a backup, and use a Holosun that has solar backup, illuminating the dot outside even without batteries.
