Great Value, Great Cell
I approached using 14500 cells with a degree of concern. A third the capacity of a good NiMH AA, even less the capacity of a Lithium Iron AA... but of course the cell voltage is over twice that of these AA's, so, from a VA standpoint, the energy is actually more comparable (but still less). Of course the big advantage is that higher voltage potential that provides more drive voltage headroom to the electronics, allowing the dramatic increase in output of lights whose electronics can handle that higher voltage. So I have bought a few lights that can use the 14500 in addition to the ubiquitous AA cells, and have enjoyed that increased power (and benefit of being rechargeable). Now my concern is that I might accidentally mix the cells and use a 14500 where it should not go - so caution on how you store these! Most 14500's with button tops are all about the same capacity. The name branded cells are more expensive, but chalk that up to being certain the name brand cells will work/fit in that maker's flashlights without issue. The Xtar cells I've bought work and fit in Jetbeam and Olight lights I've bought, but I bought an Efest that did not work in a Jetbeam Jet I Mk, but did in a Jetbeam H10A... go figure. So my experience with the Xtar has been good so far, but I can only report that Turbo Modes are active, not the output level achieved. Brightness at Turbo "seems the same" as with name branded 14500 cells, but this is clearly subjective and a poor test process when swapping cells in a light and gauging by eye. And only time will tell about the Xtar's ongoing service and cycle life as I recharge and use them over the next few years. My opinion is that only a handful of manufacturer's have the knowledge, equipment, processes, controls, and staff to make these and other Lithium based batteries, and that being true, the Xtar is likely every bit as good in capacity, service, and cycle life as the branded cells. If you're worried about this, then you can adopt a more conservative approach. You can, of course, use Lithium Iron primaries for those lights you intend to set aside in storage for "just when I need them"... you can also decide to use name branded cells for lights you intend for occasional and brief use... and you can try the Xtar brand in lights that have heavy use to gain experience and confidence with their ongoing service capacity/life and cycle life. That's what I'm doing.
ProsHave had no problem with fitting/working in several brands of 14500 capable lights. The Xtar 14500 does produce Turbo mode output in my 14500 capable lights (can't measure that output produced) Same capacity as manufacturer name branded cells; likely the same ongoing service and cycle life Good value compared to manufacturer name branded cells
ConsCaution when storing and taking these and any 14500 cells to not accidentally mix with standard AA cells, or damage to gear will result due to their higher cell voltage. Without proper testing for output current flow and a light's output, it is difficult to know if these cells provide output truly comparable to a named brand cell.

Economical Power for Capable AA Lights
For roughly the cost of 3 Lithium Iron primary cells or 9 Alkaline cells you can have this rechargeable cell which, for capable lights, can often deliver more than twice the High level of illumination due to its higher cell voltage. Of course, the capacity is roughly a third of those cells, making the break-even for general use (use at Low or Medium illumination levels) more like 9 Lithium Iron or 27 Alkaline... but given a cycle life that approaches the cited 500, savings is assured. Of course the lower capacity of this Lithium-Ion cell, 800mAH vs 3000mAH for Lithium Iron AA or 2500mAH for NiMH means less service-life, or run-time, at any illumination level. So, then, these Lithium-Ion cells are great for those who use their lights either rarely at low drain or very frequently at high drain. In the first case, about 1500 30 second uses on a typical low level of illumination will see many people through a year of EDC, and, in the second case, perhaps a dozen 2 minute uses on a typical high level of illumination will see these users get through a day with this cell to recharge overnight. Unfortunately not all AA Lights are capable of running the 14500 cell, and use of the cell can damage such devices; the cell size is so similar to the standard AA, that care must be taken to use the right cell with the right Light. Also, not all Lithium-Ion chargers are capable of charging this cell, so check your charger specifications. As technology improves, we may see higher capacity secondary cells in this size, but for now the Xtar's 800mAH is near the highest touted. As to durability (cycle life and retained capacity), that will need time in-service to prove.
ProsDirect size replacement for a standard AA cell Good, economical choice for either users who rarely use their lights at low drain, low illumination level for EDC, recharging rarely, or those who use their lights often at high drain, high illumination level, recharging daily. For capable Lights, provides a Turbo illumination level more than twice the High using an Alkaline, NiMH, or Lithium Iron AA cell. Able to be recharged by most recent Lithium-Ion Chargers
ConsDirect size replacement for a standard AA cell - in this case can be confused/mixed in use in a device that only takes a standard AA cell voltage level, damaging the device - caution and control is needed. Not recommended for devices stored for Time-of-Need use (use a Lithium Iron Primary cell) or devices that are in heavy use at high drain, high illumination levels (use an NiMH rechargeable cell).

Product is good, Price is comparable to Amazon, but slow to ship and they use DSL to USPS mail which adds several days to shipping, so you are looking at a week or more to receive product.

Affordable quality 14500
These are great cells for the price. I prefer Olights, but these are a close second. The Xtar increased the ouput and longevity of my Olight S15 Baton. Them seem to last forever and hold there charge a long time. Great investment!!
ProsAffordable, quality, true mAh output.

These XTAR 14500s are amazing lipos for small hi power tac lights. When I used them in a JetBeam 1-Mk, the max Lumen output really jumped up! Did the same with a Coast HP-1. And now that little AA light projects a beam brighter than my Cree123A dual powered StreamLight ProTac-2L! Highly recommended. Got the tip right here from other users on Battery Junction. The service is also top notch!

THESE 3.7 VOLT BATTERIES MAKE THE LITTLE GHOST VAPOR FLASHLIGHTS AWESOMELY BRIGHT!!!!!
June 30, 2015
Accurate rating, fits everything
I'm happy with the capacity, I think the rating is accurate. Fits all my lights too. The low voltage protection is rather conservative at 3.2 volts which is great (means nice long life for the cells). I like these cells -ive had my first set for about a year, in daily use in my EDC, and still going strong. This is the 2nd batch I've bought from Battery junction.
ProsGood capacity for the size Fits all my lights Xtar is good quality
ConsNone so far.

XTAR 14500 too early to say much but
Because of shrink wrap interference the negative terminal can't make contact with battery holder terminal. Emailed XTAR to see if I could remove excess shrink wrap. No Reply. Wound up using a small copper washer as a "shim" to make contact. Other than that the battery seems to work OK.
ProsAA size is correct but for the negative listed elsewhere. Works for my purpose after figuring out a fix for the negative terminal. If the shrink wrap didn't interfere I'd give it a 5 star rating based upon short term I've had it.
ConsThe battery's shrink wrap not only surrounds battery but also insulates the edges of the negative end preventing contact with some designs of battery holders. XTAR did not respond to emails concerning possible removal of wrap.

boost your AA flashlights power.
This battery gave my quark pro QPA new life. 4.2 volts vs. 1.5. Its almost twice the brightness now. Make sure you check the voltage on your light is 4.2v before using!

So far no issue.
I received the batteries and charged them up and so far no issue. I wish I should found out these batteries prior to spending a lot of money on non-rechargeable ion batteries at BatteriesPlus for my wireless thermocouples.
