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.

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

We use a lot of these for cameras. There is always, always at least one bad battery in every package and when your equipment dies, you have to find the bad battery. Poor quality control.

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!

We only use Energizer Ultimate Lithium batteries in our security products and other critical devices that need long lasting batteries. These have also been very helpful in my chatty smart remote that wakes itself up constantly—it used to exhaust standard batteries nearly every other week but now these batteries can keep it going for months. These are durable and reliable, with no leakage or safety issues so far. The packaging is standard so that one needs to be on the lookout for the Ultimate branding to find this exact Energizer variation. When these die infrequently, they are not rechargeable, so I add them to my pile to recycle and dispose of safely at the local hardware store.

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 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.

I always keep batteries on hand but at Christmas I like having the big package and good batteries for the grandkids who get toys and need batteries. Toys are great but not so much without the batteries and on Christmas day, it is too late. These batteries work well and are long lasting; overall they are a good price with the instant savings. I cannot find them anywhere else for this price.

I use these for three trail cams. They last about 9 months of continuous use, even through our blazing hot Texas summer this year. High temps frequently exceeded 100° this year. The added cost over Energizer MAX is well worth it, especially when you live 3 1/2 hours away from your trail cams.

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.
