Best CR123 ever
on April 23, 2012
I live in Japan, one of these who love flashlights(surefire).Surefire lights run with CR123 batteries, and it isn't cheap to keep using them everyday, but these K2 energy batteries just changed my flashlight-life! lol
I'd recommend it to everyone who uses surefire flashlights. (but also be careful using the batteries in non-surefire light) cuz some of other flashlights do not have the DC-DC converter so it could die due to a higher voltage. (Normally a CR123 has 3v, but this one has 3.2v-3.3v.
