Customer Ratings & Reviews

I wouldn't buy these for everything due to the price premium, but I do use them to power an outdoor temperature sensor and a small flashlight I keep in the car. Both are exposed to frigid temps in New England winters, where I find the lithium batteries do much better than traditional alkalines. "Regular" (alkaline) batteries tended to leak or just run out of power quickly in sub-freezing temps, but lithium hasn't been affected much at all. For what it's worth, they're also a good deal lighter than alkalines (and less than half the weight of NiMH rechargeables), which I could see being a consideration for say, serious backpackers or situations where an ounce would make a difference.

Batteries, as expected! They last much longer than alkaline batteries in the cold.

Started using these batteries for cameras and they are lasting much longer. With it being very cold the previous batteries were just not holding up for very long. These batteries have already lasted longer and not showing signs of being close to running low. Will definitely purchase in the future.

We have found these Ultimate Lithium AA batts last about 2x longer than the standard Energizer AA battery. We have the Yale Smart Lock 2 with wifi and fingerprint. This requires 4 of the AA batteries. The product docs say about 3 months for battery life, which is about what we got with Energizer regular alkaline AAs. Compare to the Ultimate Lithium AA that gave us about 6.5 months. Worth the price difference in this case!

I needed non-rechargable batteries for my doorbell camera. I didn't understand why they couldn't be rechargeable until I did some deep digging. Rechargeable batteries, evidently, don’t hold a charge well when cold weather sets in. These batteries have worked fine for my needs.

Great product at a great price range for your service

Energizer Ultimate Lithium AA Batteries are a great for high draw uses.

Needed to replace smoke detector batteries. Long lasting!

The only Li AA batteries worth buying. Long lasting. light weight.

Have to use lithium batteries for my BLINK camera. They last an appropriate length of time. Price is reasonable.Energizer appear to be the only brand that off Lithium capabilities

These lithium batteries are quite expensive, but they are guaranteed not to leak. I have lost a lot of battery-powered stuff from alkaline batteries that I forgot to take out when it was not going to be utilized for a while. Also, they provide full power until exhausted.

Able to power our home surveillance camera. Response time for movement notification is expected. it's been a month since installation of the batteries. Previous installation identical batteries lasted more than ninety days of continuous monitoring.

Use for doorbell camera. Seem to last a decent time. Recommend.

I purchased these batteries to put in a new device I found that allows you to put your air tag into it. These batteries will allow your air tag to last for 10 years. Great store great price

I usually look for cheap batteries, but needed something to last much longer

These batteries are long-lasting, reliable, very light and inexpensive. I have been very satisfied with the performance of these batteries. I'll be honest, I was leery of these when I purchased them. I didn't want to be caught battery-less so I purchased two packages. (One pack to carry for back-ups.) As a Mom, I use my Nikon L830 on a daily basis and after several months, I am still on the first set of batteries. The second package remains unopened. I will continue to carry them around with me though! These are well worth the money and highly recommended. Once you go lithium, you won't go back.

So far so good. Installed in outdoor wreath light sets.

This is a good product, nice battery life, I fully recommend

i use this for my doorbell camera and this is the only one that seems to last longer than other reputable brands

Excellent batteries for use in electronics, especially for security cameras. They last a long time in security cameras which is good as cameras are not easily accessed when you need to replace batteries.
