Put alkaline batteries in one string of lights and these lithium batteries in another identical string of lights and the alkaline batteries outlasted the energizer lithiums by a good margin. I was not expecting that. The value they may have is in holding their charge longer while not in use and for use in extreme temperature. They make both is these claims. I do have a string of lights in a wreath outside my door and it seems to have done well in the cold temperature but I have not compared it head to head to an alkaline battery. Way too expensive in my opinion for what they are.

Can't vouch for other applications, but for cameras, these AA batteries are the only ones I use. They last so long that eventually I change them out just because it does not seem possible that they can last any longer. Expensive? You bet - but worth it. Avoids the frustration of grabbing your camera for an unplanned photo opportunity only to find the dead batteries won't let you take even one shot. The 12-pack likely will keep your camera going for years!

[This review was collected as part of a promotion.] These batteries are good quality and do good in high demand products. I have some on my x box controller that have need in a few weeks in the past. I had to change batteries every few days. I will be stocking up for sure!

[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!

The Lithium technology is definitely superior to Alkaline, but the Lithium batteries are pricey. For normal use (remote controls, etc.) they're hard to justify, but for high-drain applications such as flashlights and digital cameras they're worth the extra cost. The fact that they are leak-proof and operate down to -40"F are an added plus.

Buy these for trail cameras. Sam's Club always has the best prices. Read a review that a club member had some that failed early on. When checked with a battery tester they registered 0.0 volts. Had the same experience with one package of 18 AA batteries. There were 6 in that package that died very quickly. Never happened before or since. Recently bought a ZTS Pulse Load Battery Tester. The only one of these failures I kept wouldn't even register that a battery was in place. So, there is no connection between the + and - terminals. Hate price has increased but these are the best batteries made.

[This review was collected as part of a promotion.] Energizer is my favorite brand of battery, so it's no surprise that Energizer Ultimate Lithium AA batteries lived up to the brand's reputation for excellence. My family loves video games and like most Americans, we're spending a lot more time at home these days, which means we're going through A LOT of batteries. Having tried just about every brand now, I can honestly say that the Energizer batteries last. the longest. If you're a gamer and you don't want your controller to die at an inopportune time, it's worth it to get the Energizer Ultimate Lithium batteries. They last a long time -- even if your kids forget to turn the controller off. Sure, they cost a little more than the store brand batteries, but they last so much longer, which means you'll spend less time changing batteries and more time enjoying your game. For the eco-conscious, that also means less waste.

[This review was collected as part of a promotion.] We’ve been using the batteries in our remote control for the t.v. in the family room. Someone’s always using the remote so we go through batteries for the remote control rather quickly. These surprisingly are still going strong. I’m definitely sticking to these going forward and will likely buy in other sizes.
