EnergizerAA Batteries, Ultimate Lithium Double A Battery, 24 Count

So far, so good. I tested all of them with a multimeter, and they show in range of 1.809v - 1.813v, for 1.5v batteries, which is great. Using them in the "(UPGRADED) AMIR Refrigerator Thermometer, Wireless Indoor Outdoor Freezer Thermometer, Sensor Temperature Monitor with Audible Alarm Temperature Gauge for Kitchen, Freezer, Home (Battery not Included)" that I bought here on Amazon. I had tried using regular alkaline batteries for that, but it went nuts once temp got below 5 degrees. I put these in, and they (and thermometer) have been fine even under 5 degrees in freezer. Easy to use, just like any AA battery, appear to be good quality, with expiration date of 12-2050. If true, they could outlast me LOL Same capacity or a bit more, than alkaline AA batteries. Definitely recommend for anything that is being used at low temperatures or high temperatures, as it's rated from -40F to 140F.

Even though lithium AAs cost a lot more than alkaline (like duracells), they have 3 advantages. First they last around 3 times longer. Second they weigh less. And third, and most importantly, they NEVER CORRODE and wreck your equipment. They are exactly the same size as an alkaline AA, and work perfectly. If the item you're using them in is important to you (or costs a lot, like a camera or flash unit), the extra couple of bucks to protect your 200-300 (or more) item is more than worth it. I also use them in atomic clocks and their wireless temperature sensors (my sensors use AAA sized batteries). Lastly, being disposable (as opposed to rechargeable) you can bring them onto airplanes without an issue.

We have used these for quite some time. With the sale price, I HAD to get more. They are perfect to use inside wireless cameras. With our camera on every single night, these will last at least a year. Perfect size, long life, not a bad price. Yes, obviously I would buy these again. Have and will again.

I may have bought too many. I'm still using the first four batteries out of the pack and they just tested with over half a charge left. I Hope they've got a good shelf life, because it's going to take me forever to use all of these.

Not much to say, they're batteries. But I've been using these for years and they do the job. I've never had a problem with them and these have been just as reliable.

The Energizer Ultimate Lithium AA Batteries (24-Pack) are a premium choice for powering high-drain or mission-critical devices like flashlights, cameras, smart locks, and sensors. I’ve used these in both everyday electronics and emergency gear, and they deliver exceptional runtime and consistent performance.They’re lighter than alkaline batteries, have a shelf life of up to 20 years, and work in extreme temperatures from -40°F to 140°F—making them ideal for outdoor or emergency use. I rarely need to replace them, even in power-hungry devices.They’re also leak-resistant, which gives peace of mind when used in expensive or sensitive electronics.Just note: These are non-rechargeable, so they’re best for gear where longevity matters more than reusability.Overall, Energizer Ultimate Lithium AA Batteries are a reliable, high-performance power source for anyone who wants maximum battery life with minimal maintenance. Worth the extra cost for serious, long-term use.

Can't say if they deserve the five stars yet. I bought them specifically for the guarantee of not leaking long term. I am using them in a Airtag holder that extends the battery life of an airtag to 10 years. I touch base again in 10 years with a follow up.

I think they are the best energizer batteries on the market for a disposable battery. The price was almost 50% off so I decided to stock up on the double A & triple A size.
