Energizer Ultimate Lithium AA Batteries, 24 Pack, 1.5V Long-Lasting for High-Drain Devices, Cameras & Flashlights

Energizer Ultimate Lithium AA batteries have been around for years, which makes them a safe and reliable choice, you know exactly what you’re getting. They have a strong reputation, and that’s one of the main reasons I chose them. I just received and installed these in my smart front door lock, where dependable power is essential. The last thing you want is your lock failing due to weak batteries, so choosing a trusted brand really matters here. They are definitely more expensive than standard batteries, but for something as important as home security, it’s absolutely worth it. Reliability matters more than saving a few dollars. So far, everything is working perfectly, and based on the brand’s reputation, I feel confident they will last. If you want peace of mind for important devices, this is a great choice.

I think these are without a doubt, the best AA batteries you can buy, even though they are pricey. They have a crazy long shelf life, are much lighter than normal alkaline batteries and most importantly, have higher output/life than alkalines. The thing I like best about them is that they cannot leak acid out and ruin/damage the battery contacts of whatever device you have them in! That is a great advantage in my opinion and makes these more or less mandatory for any "important" device you have. I don't know how many times I've had regular alkalines in something and come back after some length of time and find one or more of them oozing white crusty acidic material and have corroded the battery tray contacts. These lithiums won't do that! Since they're lighter than alkalines, that's always helpful for whatever device you use them in since weight usually matters, if it is something portable. These batteries also last a lot longer than alkalines and so are great for things that are in hard-to-reach places (smoke detectors, temperature sensors, thermostats, etc.) that you don't want to be changing batteries frequently. They are pricey compared to bulk alkalines and if you are burning through batteries, these might not be justified, but if you have anything important you want to power, I'd highly recommend these. You won't be disappointed.

Great batteries. Lasts a long time. Great fit, perfect size. Good value and great connection.

These Energizer Ultimate Lithium AA batteries are incredibly dependable, especially for devices that need consistent, long‑term power. They last noticeably longer than standard alkaline batteries, and they hold up beautifully in cold weather — perfect for flashlights, outdoor gear, cameras, and anything you don’t want dying at the wrong moment. They’re lightweight, leak‑resistant, and maintain strong performance even after long storage. If you rely on battery‑powered devices or just want something you don’t have to replace constantly, these are absolutely worth it. If you want power you can trust, these are some of the best AA batteries you can buy.

expansive but you got what u pay for

I use a electric shaver that runs on two AA batteries. The shaver is more powerful and runs far longer, perhaps twice as long. Well worth the additional cost.

My smoke detector is quite picky with battery types and only works with this kind of disposable battery. I tried using rechargeable lithium batteries before, but it kept beeping constantly and wouldn’t work properly, so I had to switch back. After installing these, the detector works normally again with no more beeping issues. Setup was straightforward—just replace and it’s ready to go. So far everything is working fine. I just hope the batteries last a long time so I don’t have to replace them too often. Overall, it’s a necessity item, and reliability matters the most.

Best lithium batteries on the market, end of story. Only downside is they're price but when you consider the performance, it's easy to justify when the need is there I've used these in everything from my carbon monoxide and smoke detectors to trimmers to trail cameras in the brutal cold Minnesota winters and they've always had great performance results

Excellent batteries.I use it for my house cameras.

duraderos, y de facil uso

I bought these for game controllers, and half of them never charge, while the other half charges really slowly, this is unacceptable.

Weder sind das Akkus, noch halten diese Batterien besonders lange. Meine RAZER VIPER V3 - Maus hat bereits nach zwei Wochen signalisiert, dass die Batterie leer ist. Warum wird nach zahlreichen Beschwerden nicht reagiert und zumindest die Beschreibung angepasst? Das ist Betrug am Kunden.

Please read other reviews regarding batteries from this company before buying. Loose batteries (not as photo advertised), in paper envelope that is unpadded, unmarked, without a transport warning sticker (required by the ACL). This is due to the fact that water, high-low temp, force being applied on the batteries can cause it to expand leading to corrosive, combustable implications. I tried kindly letting the seller know as we ordered it to our school for a class of kids to use on their science experiment. Their response was "if you don't like it , just return it to us for refund". Unfortunately this wasn't about 'like' this was more a matter about safety to buyers, and their business - as people could be injured from the sale and improper handling of the loose batteries.
