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.)

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.

These batteries work great with my blink cameras. No matter how cold it gets.

These batteries are so awesome. They last me for months in my doorbell camera. By far the best batteries for the job. Highly recommend

Good lasting battery and performs well in all kinds of things

The Energizer Batteries work as they should and are long lasting.

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.

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.

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.

Very helpful for outdoor and indoor cameras, not too expensive and get the job done.

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

Great Batteries. Useful in Wifi door lock, keeps working in cold better than alkaline batteries.

These work great for wireless cameras; the last between 1-2 yrs depending on how often the camera is activated.

Started using these on my Blink doorbell/cameras. Use them on everything now. Lasts longer than any other.

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.
