These batteries arrived well packaged and are exactly as described.

The batteries arrived in a timely manner and while they ARE what was described... one key element is left OFF the description - which certainly would have been helpful to know, prior to ordering. The posts of this battery, are not as long, as standard AA batteries. I was not planning on using them for standard replacement for AA applications , but rather, making battery charged items. The posts are not long enough, to touch the leads in a standard battery 2 or battery 3 box.

I'm really in love with these 14505's from Titanium Innovations! Recently I picked up a Peak El Capitan LED light with a High CRI emitter. The output with a standard 1.5v AA is pretty anemic but the light can handle up to 4v or so. So I picked up some of these cells- wow! They really transform that light! Subjectively the output is doubled. These really do seem to be pretty much CR123A cells in an AA body.

I was debating stepping up to 14500 cells however having small children that seem to always get a hold of my lights so the fact that a 14500 cell could be over drawn and become a risk kept me from the 14500 cells. These 3V AA sized cells work great and give me a real output boost without the added risks of recharging a 14500 cell with small children using and abusing my lights and cells.

With a terminal voltage of 3.0V, it gives most of the intensity of the light an LED flashlight is capable. It does this without the necessity of the cumbersome chargers and wallwarts that fill our drawers and closets. If ultimate intensity is needed, the rechargeables are there at BatteryJunction.com. These are a good deal.

These charge relatively fast and last almost as long as primary cells. Shelf life could be better though.

Have used these in the four sevens mini MA one cell AA but is rated to 3V. The results on high are impressive when compared to an eneloop AA. Have not tested runtimes, but having the option of a high level that equates to the performance of a 2AA/cr123 in a very small light seems a worthy tradeoff.

I was amused to just today get a "how do you like your recent purchase" letter when I haven't even received my purchase. Hopefully I will get it soon and can make a real review.

There are only certain lights in which this battery will work... they need to be capable of handling the voltage. But in the right light, you get the same output as 2xAA in the 1xAA form factor. I use it in my Olight S15-L2 and my Fenix LD10, and my Xeno E03. The Olight S15-L2 is designed to work as a 2xAA (with extender), and its circuit is actually optimized for the higher voltage -- so this is the perfect application for using this battery in the 1xAA configuration. (Don't use 2xCR14505, or you will fry the light!) The Fenix LD10 (1xAA) uses the same head, circuit, etc. as the LD20 (2xAA) version, so again it's a good application. The only caveat is that the LD10's sensitive (but efficient) boost circuit will go into direct drive when the battery voltage is even slightly higher than alkaline AA outputs, -- and so briefly when running a fresh CR14505 the low & medium & high modes are all the same brightness. After about 5 minutes of runtime (on my sample anyway) with a fresh cell, the battery voltage dropped enough that the low & med modes returned to normal. So in my experience the ~3V output of this battery is right on the cusp of of exceeding the circuit's intended input, but it resolves quickly. This behavior has been well documented when running Energizer Ultimate Lithium (L91) cells in the LD20, so I'm confident that no damage is occurring to the light. The Xeno E03 reacts slightly differently, and all the modes just get brighter :) The low mode (which wasn't especially low to begin with on this light) gets up to about medium level, and the other modes follow suit. I've read of folks running even higher voltage 14500 Li-ion chemistry cells in the Xeno without incident, so again I'm confident no damage is occurring. To my knowledge Battery Junction is the only USA distributor of these 14505/CRAA cells... and the price is very good given the specialty/limited market.

I bought these for a friend as a gift along with a Foursevens AA. I love this solution for a single AA light. TONS of power, good runtimes, and I like the flexibility and size of AA. Great product.

Pointed to these batteries from CPF...Please don\'t discontinue these Titanium Inovations! These are awesome in my Quark AA and Quark MiNi. These have enough juice to power my AA2 XML head. I think its brighter than the two Lithium primaries I have in my AA2s.

I prefer the AA battery format over the CR123 format because it is a universal cell - you can always scrounge up a AA battery. Until this product cam along, that\'s always meant sacrificing power (unless the light could handle Li-Ion cells). This product is basically a AA-shaped CR123 cell - same voltage, same performance, and very similar run-time. Like the above reviewer, I find these cells to excel in the Quark Mini AA. They also do well in the Fenix L1T/ L1D, since their circuits are also set up to handle up to 3.0V.

I picked four of these up to run in my 4Sevens Mini AA and I\'m very impressed. I don\'t have the equipment to measure lumens, but just eyeballing the Mini AA on high I\'d say that it\'s putting out at least 150 OTF lumens with these cells. Couple that with the great reputation and affordability of the Titanium Innovations lithium cells and I think they\'ve created a winner. I\'ll definitely be buying more of these.
