What are your Lithium AA & AAA batteries of choice? I have a Sig OPMOD Romeo5X that takes an AAA battery. I know the Energizer litiums are ok, but are there any cheaper choices that have decent run times?

I've always used Energizers just because they're the most commonly available lithiums and never had any issues

Energizers it is.

I guess a $4 battery every year (year to be safe) isn't bad at all for the red dot. I would use them in other devices, if i could get them a little cheaper.

Amazon has them for way less than $4 a battery:

I worry about fakes on Amazon. They are about as bad as eBay.

I like Energizers because you can see them when you drop them on the ground.  Value added.  A Duracell will disappear on you!

Have used a chinese company called BEVINGOR or some such from Amazon, it's like .50$ per from them and they work fine.

This. Won’t put them in NV or expensive electronics but they’re great for flashlights, radios, etc that get stuck in drawers for years.

If you're a Sam's Club member, they sell 18 packs that work out to under $2 each. Get them in store or have them shipped to you.

Looks like Sam's Club lowered the price of the AA lithium batteries by $6. Not sure if it's a sale or just lowered temporarily, but they work out to about $1.61 each right now.

Cheaping out on batteries for weapons is a false economy. Buy rechargeables for other stuff to save money, but spend the extra $2 apiece to buy decent batteries. It's the equivalent of 4-5 rouds of decent 5.56.

I only buy Energizer for AA and AAA lithium.

Energizers only. I bought some generic ones off Amazon a few months ago just to try, and they seem to last 1/2 as long in flashlights, so sticking with Energizers in everything that takes lithium AAA

Energizers.. my sordins are stupidly picky but a pair lasts quite a few years for me shooting on a solid regular basis. 2-4x a month

EBL rechargeable batteries is what you seek, they will not fry your electronics. I use them in my NV devices.
