[This review was collected as part of a promotion.] These seem to be longer lasting than regular batteries. Put them in some devices that usually eat up batteries and so far so good. Hoping to finally have found some batteries that don't need to be replaced so often!

[This review was collected as part of a promotion.] Great batteries that work and last so long! This is the only brand I buy and I’m happy each time with how they perform and how long they last! Always outlasts other brands I’ve purchased by a long run!

[This review was collected as part of a promotion.] Energizer has always been my favorite brand, they keep going and going but this time IT REALLY DID! Batteries do NOT work in my gaming controller for more than an hour of wireless play, but here I am at hour 6 of playing and still going strong!!!

[This review was collected as part of a promotion.] These Energizer batteries are perfect for long lasting . They come in a four pack . They are 1.5 lithium . I use these for my kids came system remotes and they use the remotes a lot. They have long lasting while using them. They have actually kept the remotes on overnight and still it hasn’t killed the battery .

The Energizer Lithium batteries last a long time. We all go out and pick up the occasional battery package, perhaps a store brand here or there. But, Energizer brand lasts the longest, especially for items that get used on a daily basis. Reliable, affordable, and easy to find at most stores. I don’t want to have to guess if the flashlight will work when the power goes out, and that’s where Energizer Lithium batteries, take the guesswork out of the question.

You can tell the difference in quality of the brands of batteries easily. Some just don’t last long. These are the only batteries I’ll use. They actually last a really long time. We had these cheap batteries that came with some Christmas decorations this past year, and they just kept going out. Put these in and I didn’t have to change it at all after that.

So these are some of the most reliable batteries in the market I would definitely recommend for any use whether it be military civilian or law enforcement these are very long lasting very durable batteries try to keep them away from water and extreme heat.

The Energizer Ultimate Lithium batteries are rated for extreme temperatures. we have extreme lows and extreme highs as well. The batteries are also rated as being leakproof which is a big plus. A battery that leaks can ruin our outside weather equipment.

So, these are great for those devices that you don't want to replace often - smoke detectors (yes, looking at you Nest using 6 of these), wireless cameras (Blink Outdoors), etc... They last more than a year in each of these cases, and sometimes longer. Where wouldn't I use these? In any kids toys - they don't have significantly more juice than the regular alkaline, and so in devices that will plow through batteries regardless, these simply are way too expensive, and it's back to the cheapest alkaline or a rechargeable for those. But when it has to work, and you don't want to replace often, choose the Energizer Ultimate Lithiums and you can't go wrong!

[This review was collected as part of a promotion.] Energizer batteries never let me down! My kids have a night light that take batteries and it's the end of their world when the batteries die. I noticed the lights getting dimmed and tried these batteries and the light was so bright. I let it stay on all night a few times and it's still as strong as ever. Great batteries for sure!
