Energizer Ultimate Lithium AA Batteries Pack, 1.5V AA Batteries, 24 Count

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.

These batteries last a long time and they are worth the price you pay. Grateful that Amazon sells them. Nice to have them shipped to your home.

Sure, these batteries cost more per battery than dollar store batteries. But they last insanely long. I didn't appreciate how well they last until I tried to use some standard Energizer batteries in a Blink camera while I waited for more lithiums to come in - and the standard batteries died in *2 weeks.* I have a Blink camera mounted somewhere that is STILL running on the same original Energizer Lithium batteries *4 years* after I put it up.

These are expensive batteries compared to normal alkalines but they have much longer shelf life, longer life in use, and I have never had one leak. They are also lighter, which can matter in some applications; I have flashlights that will float if these batteries are in them but sink with alkalines. Mostly we use these in security cameras and security lights where utility power is not available so we don't have to change them frequently; Alkalines might last 60 days, these will go almost 6 months.

Long lasting. Performs much better than the other brands. I use these exclusively in my deer motion cameras, which take hundreds of pictures in a few days. Beware of knockoffs.

Always pricey, but best price around!

I use these for my Blink Cameras. These seem to work best with them. A tad expensive in my opinion but works better then other brands.

Sometimes you absolutely must use Lithium AA's. They cost significantly more but they don't leak acid in you expensive handheld electronics! They do actually last longer due to the technology of Lithium batteries. I started using them when I had a Vortex red dot scope quit when the battery leaked. I cleaned everything spotless but it had ruined the electronics in the scope. My saving grace is Vortex's unconditional warranty, they rrplaced it for free!! Believe me when I tell you, you want these batteries in anything you love that needs batteries you are not ready to let go of. Scopes, GPS units, Laser range finder units, HF handheld radios, etc.
