Have purchased 3 packs over the last few months and had several from each pack drop to 0 volts within a few days of use, while others last up to 9 months.

Excellent performance, new technology that should become a standard. Hopefully the price will come down as there is more adopotion. Still have calculate the expense versus the frequency of replacement relative to nicads

Will be returning. Installed 12 brand new batteries in my trail cam and showed 70% battery life from the start. Within a week 60%. Could be one bad battery could be more. I’ll return to alkaline and save money and time.

These are hands down the best AA batteries there are. I use these in all kinds of devices. These batteries even work in temperatures below zero without affecting performance or life. They are great and extremely reliable.

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.

Lithium batteries have risen in price quite a bit in the last 2 years. This 18 pack at Sams Club is the best deal I have been able to find on Energizer Lithium Batteries. I tried a couple of generic no name offerings that were a little less expensive, but they did not perform as well as the Energizers. These batteries perform well in extreme weather conditions, but they also last longer than standard akaline batteries in normal operating environments. I have a couple of devices that go through standard Energizer Max and Duracell akalbine batteries in about 6 to 10 hours of use. I decided to try lithium batteries in the same devices and got about 3 to 4 times longer life of the batteries. Even though they cost more, they were actually cheaper to use because I didn't have to replace them as often as the standard alkaline batteries.

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.

Could not find these batteries with the other batteries. Found the AAA versions but not the AA version. Asked a number of Sam's Associates but they were no help. I told one associate the store inventory showed them in the store but was told inventories were delayed by as much as three days. So I ordered these batteries for curbside pickup the next day. Second day I made a trip to curbside pickup and got the batteries.

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.

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.
