[This review was collected as part of a promotion.] This is by far the best battery I have had the pleasure of using while I work. I used 1 batter in a old mp3 player I've had for 10 years or more and left the player in the walk-in freezer. I figured for sure the bettery would be to frozen to use and I'd have to defrost and hope it still worked afterwards as with many batteries before. When I realized after 2 hours of it sitting in the freezer it was there and pulled it out I was amazed that it played no problems. This isn't the first time I've left my mp3 player in a freezer it's just the first time it actually worked after being forgotten. I am still using this same battery and it has been playing 8 to 9 hours a day now for 8 days straight. I am very impressed with this battery.

[This review was collected as part of a promotion.] Batteries have come a long way over the years. Energizer ultimate lithium Batteries fit very well with their product lines. They boast a 20 year shelf life and "work in extreme temperatures". While I can't rate the 20 year shelf life, I think Enegergizer usually lives up to their promises. I feel quite comfortable putting these in my emergency flashlights as well as my TV remote. In today's world, with all our electronics and gadgets, we need a battery we can trust will work.

[This review was collected as part of a promotion.] I was impressed with these batteries. They last forever even in a high drain electronics. I will definitely buy these batteries again. The packaging was easy to open.batteries in my camera usually only last a week and these are 3 weeks going strong.

I used them in a children's piano, with three octaves, which didn't sound good even with the batteries freshly installed. With these batteries the sound is very clear, we are delighted! I have also used them in my Bresser Biolux microscope, and the LED is brighter with these batteries than with the ones I had as standard. Come on, I can only talk about these batteries. I will buy more in the future.

[This review was collected as part of a promotion.] The Energizer Ultimate Lithium AA Batteries are good for all of your electronics that require a dependable battery. I am using these in my computer's mouse and my TV remote control. Everything is working smoothly and this is a go-to brand of mine. These offer a bit of extra time with the 1.5 V Lithium, which I appreciate.

[This review was collected as part of a promotion.] These are my go to batteries for everything! I especially like using them in my children's toothbrushes. Most other batteries die super fast in them. But Energizer keeps them running for so long. I also have a lot of remotes in my home so making sure they all keep working is super important, with Energizer I don't have to worry about that!

These are usually the brand I go for when looking for batteries. I don't notice a significant difference or anything in longevity, except for those cheap batteries that often come included with things, I think I've just always liked the energizer bunny lol so kudos to their marketing team I guess

[This review was collected as part of a promotion.] I have a household that uses a lot of batteries for everything my teenagers and myself use. These batteries work great. They are easy to open and easy to exchange. The batteries seem to hold life longer than the stores generic brand. Which is perfect for the multiple gaming systems and remotes. More bang for your buck!
