Energizer Ultimate Lithium AA batteries are known for their exceptional longevity and high performance, providing long-lasting power for high-drain devices and ensuring reliable operation in extreme temperatures. Their lightweight design and leak-proof construction add to their convenience and durability, making them a top choice for critical devices like digital cameras and remote controls. With an impressive shelf life and consistent energy output, these batteries offer both efficiency and dependability.

These batteries are compatible and work well in various devices, particularly in outdoor cameras and remotes. I appreciate their long lasting compared to alkaline batteries. It lasts around 6 months. Good quality. They’re much lighter than traditional alkaline batteries, which is great for portability, especially in gadgets that you need to carry around. It's expensive though. Overall, they’re reliable and efficient.

[This review was collected as part of a promotion.] The Energizer Ultimate Lithium AA Batteries, 4 Pack are great long lasting batteries. They are the only brand I will use in my children’s toys to ensure they stay working for a long time. I couldn’t ask for better batteries.

[This review was collected as part of a promotion.] Energizer - Energizer Ultimate Lithium AA Batteries (4 Pack), 1.5V Lithium Double A Batteries are great. If you want performance you can't go with cheap batteries and these are the top of the line. They last longer than other brands and can take freezing temperatures, if you ever needed to grab a flashlight in your car on a cold dark winter night you know that can be important. Get some today, they have a 20 year shelf life so you can stock up on them.

These batteries are awesome.&nbsp; I have 4 Nest Protect smoke/carbon monoxide alarms in my house.&nbsp; 3 of these are battery powered and take 6 of these batteries EACH.&nbsp; The 4th one is wired and uses 4 for backup purposes.&nbsp; Ive had these units for several years now and they&nbsp; have maintained the protects wireless network, software updates, automatic tests and manual tests for those several years and they have yet to be replaced.&nbsp; (the protect units will let me know when)<br>

I purchased these on a whim. There wasn’t any research behind the purchase. They’re honestly just ok. They didn’t last any longer than the other Energizer brand batteries. If the price is the same as the other versions, I don’t think there’s any reason to buy these specific ones.

JUNK is a compliment compared to my experiences with Energizer Ultimate Lithium AA batteries. In case it was a fluke, I purchased them from 3 different big box major retail stores over a period of several months. Put them in TV remotes, electric window shade, Microsoft Mouse, front door lock, 2 flashlights and these batteries repeatedly fail FASTER than that fake bunny can wiggle its tail!FYI, I have 40+ years of tech skills and in all those years I've never experienced worse batteries. 

I have the lithium a try...can’t say a very noticeable extension of life or power (emergency Xbox controller batteries) but definitely out perform cheap store brand regular alkaline batteries. Trying to use rechargeables anywhere I can but these are always in the drawer as back up.

[This review was collected as part of a promotion.] I have a motion sensor trash can that constantly needs replacement batteries. But these ones have lasted way longer than the basic batteries you can buy. I like them also because I've always trusted Energizer batteries. They always last slot longer than the other brands. Thanks Energizer!

[This review was collected as part of a promotion.] I received a pack of these to try. We put these in my husband's game controller we are constantly changing the batteries every few days because he uses it so much! We have noticed he has full power on it still and it's been a few days of usage. I believe we found our newngo to batteries these last a lot longer than other batteries .
