This is the first time I have used Energizer batteries for years. I decided to try them after I researched which was the better battery, Duracell or Energizer. So far, they last longer than the Duracell AA batteries.. The price wasn't too bad because of the instant savings. I checked COSTCO's and SAM'S CLUB was cheaper.

Great Batteries! These last a long time. I use these in my insulin pump and also flashlights. My pump runs 24/7 and with the Energizer alkaline batteries I usually get 3-4 weeks from them. These lithium give me at least double that time! I've been using them in my pump ever since they came out. Highly recommend!

I have several game cameras on my property and they all need lithium AA batteries. I have bought battteries from many on line and brick and mortar stores over the years. These are pricey batteries and Sam’s Club has, by far, the best price of anyone else. And they sell batteries with the longest ‘good for” dates. This is my go to place now for fresh batteries, Take my word for it, I’ve spent hundreds of dollars on batteries before realizing Sam’s had them when I was wasting my money elsewhere,

I used to go through lots of alkaline battteries until I purchased Energizer Lithium AA batteries. They last months longer. I have a digital recorder that would eat alkaline batteries in a week or two. Now with the Lithium Batteries it will last six months before I have to replace it. I have lots of items that use AA batteries and form now on Lithium is the only battery for me.

I have only used a couple of them so far with no issues. I purchased the Energizers, having been a long-time customer of another major brand, which I needn't name here, but they have a copper top, because I have had several leakages, both in use and even still in the package. They assert a 10 year shelf-life. That hasn't happened recently. So, I am switching brands. I hope Energizer's 25 year shelf-life means they will last at least long enough to put them into service.

I purchased these believing they would last longer than my Duracell brand. I wanted it to work but unfortunately they did not last even as long as my Duracell nor even energizers. I put them in our star on our Christmas tree and it went through three batteries in only four nights. At least I got six days out of the Duracell. Perhaps these would be better outside in a remote for temperature. All I can say is that will be my last time I buy these. I even watched videos claiming they were better and would last longer. These are average at best and for the price below that.

These batteries will recommended by the company that makes my wireless security system. Perhaps they overstated when they said these batteries will generally last 2 years with average use. I got nothing more than 3 weeks out of any of them before the power was too low to run the camera.

Purchased these Lithium batteries to use in trail cams since Alkaline batteries cannot be used during the freezing weather. These batteries work reliably for one year in the cameras, and are online every day without fail. Sam's Club offers them at a very good price, too.

Great batteries, long life, no corrode. Easily out performs alkaline. Used in outdoor equipment under all kinds of conditions. Do protect any batteries from water exposure. These batteries will not promote the destruction of your devices like Duracell alkaline batteries do.

In the hopes of having my battery operated Christmas lights last throughout the season, I purchased an 18 pak of the AA Energizer ultimate lithium batteries. I bought these from my local Sam's Club. My light strands were either fairy or micro led lights and required 3 AA batteries each. The number of led bulbs ranged from 18 (micro) to 30 (fairy lights). I used all 18 lithium batteries in 6 strands. These were all on timers (5-6 hours) and I wouldn't consider them as high drain. Much to my surprise, they only lasted a little over a week. The regular AA alkaline Energizer batteries at least lasted two or more weeks. How do you explain this? The packaging claims "%231 longest lasting batteries". I paid $34.99 for this pack of 18 batteries !!! That was $10.00 more than a 48 pack of regular AA Energizer alkaline batteries. This was a total waste of money and I definitely don't recommend! Not sure if this is typical or I just purchased a bad batch of batteries. I sent an email to Energizer customer support for their input.
