It is very frustrating to have batteries losing power in your camera. No problem with Ultimate.

the Energizer batteries are great batteries- long lasting, durable and very cost efficient for any of your home electronics, outdoor gear and more

Always use energizer or Duracell. Leakproof, long lasting and powerful

Just bought these batteries yesterday for a lint remover Best Buy came and clutch. These might last a long time.

BEST BATTERY!! LONG LASTING WORKS GREAT WITH MY MEDTRONIC INSULIN PUMP : )

Bought these batteries for my blink cameras. I have 2 doorbell cameras and 4 outdoor cameras. The batteries last quite a long time IF I remember to turn the cameras off while doing yard work. If not, I have 200 videos of me walking back and forth, draining the batteries unnecessarily

These batteries are the gold standard for power-hungry gadgets. My smart smoke detector quickly drained the previous standard alkaline batteries I used, which was a constant hassle. I upgraded to this Energizer Ultimate Lithium batteries, and they have been performing flawlessly ever since and in good health. Such reliability is crucial for safety devices like this. The battery performance is definitely 5 stars and is well worth the price for the long life and peace of mind. (Note: The packaging was not in a perfect shape upon arrival, but the product inside was completely undamaged and functional.)

Definitely buy lithium batteries over alkaline. They last 3 times longer. I have tried different knock off brands from amazon but duracell last the longest by far.

Very good and durable. I used a different types for my Blink cameras and didn’t last 1/4 of the time these ones last.

These batteries are very l9ng lasting, lightweight and never leak. They are perfect fir high drain devices. Best of all they are not affected by hit or cold temperatures.

Didn't realize the type of battery and possibly the brand made a true difference in the working of a product. At first I had bought cheap, then read instructions which stated the required battery to function. It did matter.

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.

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

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 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

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.

The batteries are good and last pretty long. Also, they are the only ones recommended (or accepted) for my Blink cameras. I don't understand why they would make devices with such specific battery requirements, just use a rechargeable. But whatever, these work.

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 are pretty good, gotta get out a good Best Buy membership price, they last pretty well do what I have to do

when you are putting your homestead and occupant's life on the line every night, having a working smoke detector is worth the price. One of the sadest finding at a fire scene, is the smoke alarm dangling by its wires, having had the batteries taken out because the alarm kept beeping a "low battery" alert
