Long, long battery life & lighter weight too

These batteries have a high lithium content and I've found them to absolutely deliver on their promise of long lasting power. Considerably longer life in my experience. The only downside is this longevity comes at added expense, no question these are some of the more expensive non-rechargeable AA's. So far as I know they are the only batteries recommended for the Nest Protect, which with 6-AA Ultimate Lithiums helps the device live up to it's promise of 3-4 years on a set of batteries... Also note that these Ultimate Lithium batteries are noticeably lighter in weight than typical alkaline batteries, an added bonus I suppose, if you're looking to shave weight perhaps in a remote control vehicle or pocket flashlight. Purchase these if you need longevity in any AA battery powered device, or in AA powered devices with a high drain, you'll have more juice for longer play/run time.

Must buy for serious video gamers

Very happy with these, going to stick with lithium instead of alkaline from now on. I use these in my gaming controllers, and they provide a number of benefits: Lighter Leak proof Last longer As a serious game collector, The biggest thing for me is that I will never again have to spend time with rubbing alcohol scrubbing battery acid off a controller!

Where have these been all my life?!?

I always get subscribe and save batteries and somehow lithium just showed up and I don’t know where these have been, but they last forever it is amazing and they’re a little bit more expensive (of course they are) but worth every penny! and they don’t have the AAA yet in the subscribe and save but do have a AA and I use a LOT of those for many things around my house like cameras and remotes and you name it and they don’t EVER die so very very happy with these! I will never go back to alkaline again! ⭐️👍⭐️

Excellent batteries

These are the best AA batteries I've ever used. They last very long, the voltage doesn't seem to drop until they are almost dead, and they can provide high current for extended time. They never seem to leak, even after they are left in a device after they are depleted. They weigh quite a bit less than comparable alkaline batteries, thus, they are ideal for applications where low weight is desirable, such as wireless headphones, headlamps or flashlights that take a large number of batteries.

Great batteries

I have a Blink Wi-Fi security camera on my front porch. I was having a heckuva time with batteries. I ended up getting two sets of AA rechargeable batteries and they would wear out after a few days. Then I did some research and these batteries were recommended to me. I thought that they were a little pricey but I decided to check them out anyways. I have to say it’s been two weeks since I’ve inserted the new batteries into my camera c I have a blank Wi-Fi security camera on my front porch. I was having a heckuva time with batteries.

I have to say it’s been two weeks since I’ve inserted the new batteries into my camera & The camera gets plenty of usage especially on my front porch. The battery still has a high-level and is not fall during or flickering or causing the camera to get glitchy. A lot of views with their normal rechargeable batteries cause the camera to be glitchy right before they had to be changed again. Quite impressed with how strong these batteries are, this particular package seems to be stable and powerful, etc. definitely a good investment especially for items that need strong long lasting batteries

Cost more but pays off in longevity for speedlight flashes.

These Ultimate Lithium batteries are all I use for my speedlight flashes. They recycle much faster than alkaline and lasts a whole lot longer, 8x longer. Interestingly, when a battery goes out, my flash pretty much stops firing due to the drop in voltage, so I know immediately to swap out all the batteries. Using a battery meter, only 1 of 4 batteries have severe dropp in voltage, while 2 or 3 of the other batteries still have good enough capacity to be used in other devices for quite a bit longer. However alkaline's simply drop off linearly and when my flashes take too long to recycle I change them out. When metering the alkaline's they are pretty much equally depleted.

Noticeably more power

As a rule I use grocery store brand batteries in everything to save $$$. Over time though, I find it is far more convenient to use these in electronic gadgets that are not easily accessible physically, and/or for those items that need to work reliably i.e. a security system sensor vs. a cat toy (you decide which is which). Comparing these with generic alkalines, both fresh out of the box, these show noticeable more power in motorized items. Would purchase again, hopefully not real soon.

They don't leak - I hope

I'm tired, like the rest of you, of having AA and AAA alakaline batteries leak and ruin equipment. I went to these primarily because I don't think they leak. If I ever get a leaky one I will post another review. The pros for these batteries are longer shelf, operating life and hopefully no leaks. The con is higher cell voltage - approximately 1.75V vs 1.5 for a fresh alkaline. I had a TI calculator that didn't do well with the higher voltage. I put a small silicon diode in series with the pack and it worked fine. Overall I don't think the higher voltage is an issue. By the way - the Kirkland AA and particulalry AAA are almost guaranteed to leak.

Awesome! Last longer than expected

I was a little doubtful with the negatives but as usual it seem people with no clue what they are doing gave bad reviews. Received the battery pack and tested to be fully charged. I tested with the charger and it doesn't charge any more. Installed the battery in the flash light and it keep going on for a long time that I am started to get annoyed as the battery don't discharge soon enough. It had been so far a great buy compare to the NiMh and cost less than the weak boys. I will not go back to NiMh at all since we have not experience any thing like this. I am pretty sure you will not regret with these batteries at all.

excellent

I use these instead of alkaline batteries in my trail cameras because lithium is not as susceptible to cold temperatures and my cameras are outdoors in the midwest 24/7/365. I get a year or more out of each set of batteries and my cameras work to 0-5 degrees F. On alkaline batteries, the camera stop working around 10-15 degrees F. So I get longer battery life and a bit better temperature performance out of these.
