Reddit mentions of SureFire SF12-BB Boxed Batteries, (12 Pack)

Shelf life on lithium primaries is about 10 years...

Don't usually recommend their flashlights, but I do like their batteries, and this is a pretty damn good price on these Surefires.

It wasn't horrible battery life, but it wasn't great like my T2, which has battery life measured in years.

It's kinda confusing at first, the XPS2 & EXPS2 are the non night vision models with the CR123 batteries. The "E" models have a riser plate for clearing something like laser device. The XPS3 & EXPS3 are the night vision compatible models. The number after the model number, like if it says XPS2-0, is the designator for the reticle.

I picked the XPS2 originally because i had other gear (my headlamp & M300) that used the CR123 battery as well. I rather have one battery type if possible in my bag, as opposed to having to remember to bring multiple types of batteries.

If you get one that uses CR123 batteries, get a 12 pack on Amazon like this one, it'll be much cheaper than buying them in store at Walmart or Walgreens. If you go that route, get a battery caddy to keep things organized in your range bag.

Hope that helps a bit!

You and me, both!

Welcome!

Two important things I learned here:

• The incredible value and functionality/performance that Li-ion batteries bring.
  
  
• How generally overpriced and underpowered retail lights are, compared to the value and performance of companies like Convoy, Wowtac and Thorfire. (Those are just the ones I have first hand knowledge of)
  
  Looking at my Amazon history, these were the batteries I ran in my pre /r/flashlight flashlights. Never again!

Thanks! I like your 17 as well, and I'm sure you like the 650 lumens you're pushing out of that 1HL.

I found these at a decent price. Good suggestion.
