I don’t really understand the differences in batteries. But let me tell you I feel like these last longer than others. I am able to use them in many items in my home and go months without changing and I use these things daily multiple times. I’d definitely purchase again.

[This review was collected as part of a promotion.] These are an excellent value and these batteries will last FOREVER! I have had them in my remote for almost 3 months now and they are still working great. You may think that the price is a little “high” but they will last you longer than traditional batteries which in turn will save you money in the long run! Would definitely recommend.

Energizer AA batteries are a reliable and long-lasting power source. They provide consistent and stable power and are resistant to leakage. Highly recommend for anyone in need of a reliable power source. Worth the extra cost due to their exceptional performance and longevity.

These are the best batteries there are. They are a lot of expensive brands and these are kind of pricey but they seem to last the longest and my kids toys and let me tell you we go through a lot a batteries! My only wish is that they weren’t so expensive!

[This review was collected as part of a promotion.] I’ve been using Energizer batteries for as long as I remember. They are great quality, and these don’t stay behind. I love that I can use these for my kids toys or remote controls and they last pretty long.

[This review was collected as part of a promotion.] I absolutely love Energizer Ultimate Lithium Batteries. These batteries can handle extreme temperatures. Which is great in Florida. These Ultimate Lithium Batteries can be stored up to 20 years without any leakage. I will definitely be using them from now on.

The Energizer Ultimate Lithium AA batteries were recommended for my home weather station in the outside the house transmitter. It was indicated that regular batteries (non-lithium) can freeze up a bit and not give accurate readings in very cold weather. Since it is sometimes minus 20 degrees F here, I used them. They have worked perfectly this winter with no problems. It has been 20 below here on occasion. Good Product.

[This review was collected as part of a promotion.] Energizer's Ultimate Lithium Batteries last a long time, making them high a quality and durable product. The batteries are easy to install/uninstall. The batteries are easy to store and stay fresh for a long time.

Great batteries, I only take away a star for the price but I guess with how long these last and not having to buy more frequently it’s a decent price overall. These definitely last long is any item I’ve used them with and I like the shelf life guaranteed for 10 years so I can’t buy them and have them in my house for whenever I need them

Energizer comes in a close second to their main competition in my opinion. They're still way ahead of the cheaper brands and perform well for the money. You really can interchange this brand for any of the top competition and you'll have pretty similar results. This might just come down to brand preference or loyalty.
