Customer Ratings & Reviews

By far the best battery out there I have used many batteries before to power oculus rift controllers and the Energiser ultimate lithium last the longes great buy for the price you get double the power

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

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.)

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

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

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 : )

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.

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 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.

The best and required for Blink cameras. Lithiums are always more expensive, but they last long enough to make it worthwhile.

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.

Only battery of choice for my Blink cameras. Decent price as a plus member.

Long lasting batteries, they do cost a little more, but it's worth it.

I don’t trust any other batteries these last long and our indoor and our outdoor cameras

Awesome batteries that is what I used for my nest smoke alarm last last long time over too years and counting

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.

Great product, I am using it my blink cam. Just one word excellent

These are very reliable and long lasting in my experience.

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.
