I did a search for "best 16340", but the most recent relevant review of that battery type was from back in 2014. I was in the process of recharging my Jetbeam 16340, after using its 100L medium setting for an extended period, each of the past 2 nights. I was comparing my estimate of how long it ran tonight, with the official Jetbeam specs listed at batteryjunction, and the Xtar VC4's measured amount of mAh charged to that battery.
While at batteryjunction, they were advertising a few Jet II mk compatible batteries on the bottom of the screen, which included the Jetbeam JL160 680mAh 16340 that came with my light in a deal at Amazon. They also list the Efest 3540 black 16340 that's advertised at 850mAh. I already read a 5 year old HKJ review of that battery, which wasn't particularly positive. Its capacity is bunk, as is consistency between batteries.
So I decided to post a fresh thread, where people can read and find info on the best 16340(RCR123) batteries AND the best 18350 batteries in 2018(although I don't personally own any 18350 devices). The criteria would be related to 1). High overall quality and durability, 2). Maximum safe capacity, 3). Consistency between multiple batteries of the same brand & type.
