Many years ago I purchased a Four Sevens Quark 123. At the time, CR123 batteries were a specialty item, found only in a few stores or online. Not wanting to buy CR123 in bulk, I shied away from using this flashlight. Fast forward to today and with this 16340 battery, which fits the light perfectly, this little light is now part of my EDC. Price was good and delivery was fast. I'm a satisfied customer.

Great batteries, fast shipping, thank you!

This battery really packs a punch for such a small size. It holds its charge for a long while so it will be ready to deliver the power you will need when you need really it. I highly recommend the purchase of this battery when you need a CR123 size battery, but want something more powerful.

Bought 2 of these to use in my Fenix flashlight. One in the flashlight and the other as a backup. Ready for the dark nights ahead.
