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.

Need it for the door bell! Quality is good and can be used for a long time!

these are the best batteries in the market. and they don't leak the way regular alkaline ones do.

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

Best Batteries Ever, the Energizer Lithium Battery Series are the strongest batteries available anywhere. For some electronics like portable WiFi cameras some won’t work properly unless you use these types of Lithium batteries. I always keep various sized of these batteries in my spare battery cases plus they have a long shelf life.

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

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

Good lasting battery and performs well in all kinds of things

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

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

Great long lasting batteries that do not leak! Recommend!

I don't know what Energizer does with these batteries, but my Nest spoke detector runs for a year or so on these, but chews up other brands in weeks! While they are expensive compared to other brands, not having to change them out every week is worth it!

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.

These batteries last in a blink camera and my Xbox wireless controller for months these are a must have

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

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.

Good batteries. Last a long time in my Xbox controller.
