Energizer L91 AA 1.5V Ultimate Lithium Battery

Long Lasting

The Energizer L91 AA Ultimate Lithium Battery stands atop the AA market when it comes to both efficiency and reliability. These sophisticated cells boast an impressive capacity of 3000 mAh and can produce a staggering 3 Amps of continuous current. The L91s seem almost everlasting, able to last up to 8 times longer than your standard alkaline battery, making them perfect for any number of electronics including flashlights, digital cameras, remote controls, hand-held gaming systems, and much more.

Unique Chemistry

The L91 features a specialized Lithium Iron-Disulfide chemistry (LiFeS2) that gives it not only superior power compared to average primary batteries, but incredible reliability, able to perform extreme high and low temperatures. A higher operating current and flatter discharge curve allows the cell to perform better for longer periods of time than ordinary alkaline batteries and is even notably better to other types of Lithium cells. The battery's Lithium chemistry is also remarkably safe, with superior leak resistance and making unstable chemicals like lead and mercury obsolete.

Love the Lithium
Love these batteries. Use them in electronic devices where i don't have to change out the batteries often. And i no longer have to worry about Alkaline leakage (which recently happened to my mini lantern flashlight). -M.

Ultimate Battery Tech - for now
Once upon a time, in the late 80's early 90's, engineers in one of my departments were responsible to evaluate the early version of Energizer's Lithium Iron DiSulfide AA battery for consumer use in our gear. Very impressed, but, especially back then, too expensive to consider. However the evaluation testing results were beneficial. Leftover batteries made their way into drawers here and there, one was mine. It's now nearing the end of 2017, and just recently I found another box of four. I had found two of these still alive and well, making my just-in-case, emergency-in-the-drawer Mini Maglite's shine just fine. So one of the new (old) one's is powering a new LED flashlight right now, too. Think of it... an early version demonstrating at least 25 years of shelf life, delivering power as if new. (Haven't done a deliberate run-time test, but their "still going".) Further, the Lithium Iron DiSulfide cells provide useful output down to -40F. One of my camping buddies just went out this winter to test his new winter gear. He was surprised that his cell phone battery dropped half its charge in one call at 15F, but that's what Lithium Ion's do, and don't try to charge them cold, either! (Keep that cell phone next to your body to keep it warm for an emergency call.) The Energizer Ultimate L91 AA and their AAA and 9v, represent perhaps the ultimate in battery tech for low temp use and shelf life, as well as delivering both high capacity and output current.
ProsLong experience and expertise in the manufacture of these cells. Demonstrated good low temperature performance Demonstrated extremely long shelf life Demonstrated high capacity and output current
ConsNon-rechargeable technology Premium in cost (but clearly worth it)

Packed with power
Lithium primary AA batteries... if you know enough to be looking for this product, then I don't need to say any more. If you don't know why you'd want these batteries, then let me just say that you get more power with less weight (okay, less mass), MUCH longer shelf life, and no risk of leakage and corrosion.
Pros+ Longer shelf life + Lighter weight + More power + MUCH less risk of leakage and corrosion
Cons- Higher initial price than alkaline batteries

Best price around for a great, long-lasting battery
In the security industry we use batteries. A LOT OF BATTERIES! I have started out ordering a few at a time from Battery junction just to make sure the batteries they were selling were not batteries that had been sitting on someones shelf for years and they bought and were reselling and were going to go dead in a week. Battery Junction is great, their products are great and I will continue to order these and other products from them.
ConsWould like more "promo" codes as incentives to purchase higher quantities.

Battery Power
What can one say about batteries. I put them in the device and it works. so I guess they are doing what they are supposed to do. The real test is how long they last. Since I just installed them, I cannot address that issue. Ask me for a review again in 3 to 6 months to get a more realistic assessment of the quality of these batteries.

Great at High Current and No Leakage
I was pretty naive when I first bought a few of the L91s--I saw the Ultimate Lithium advertising and was pretty skeptical about the idea of this AA being better than your standard Alkaline AA. I did some testing and found out it is very well performing at high current. At low loads, it's pretty comparable to your standard AA battery, except it didn't leak. Ever. Due to its higher voltage, it also has much more energy than alkaline batteries.
ProsProvides more energy than a typical alkaline primary, and lasted ridiculously long in my digital camera. These L91s have never leaked, and they also have a crazy long storage time and perform very well in the cold.
ConsNot really anything significant other than that at low loads it's pretty comparable to alkaline primaries, except for the fact that it does not leak.

These things last forever!
These may cost a bit more than regular alkaline batteries but they are worth every penny!
ProsLonger run time Longer shelf life
ConsCosts more than Alkaline batteries
