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

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.

Good value, energizer quality, long life.

they work great and not went bad yet Fit good easy to use

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.

These are great. I use them in my security cameras. They last a few months with the cameras running 24/7. I now have them on subscription delivery so I never run out.

expansive but you got what u pay for

These are the best AAs available

Bought these on a lightning deal. I usually buy the off brand due to the price of these, but got a good deal. Great for replacing my security camera batteries. They usually last well over a year in my cameras. Quality brand and zero issues.

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.

Las mejores baterías de litio sin duda

been using these batteries for over 10 years and they have not deceived me

Lithium batteries the best

La calidad esperada a un precio excelente, es una lastima que no se comercialicen en Amazon Mexico directamente.
