POWEROWL Lithium Batteries AA High Capacity Long Lasting, 1.5V Double A Battery for High-Tech Devices - 8 Pack

I simply cannot fathom how these are so much better than every battery ive bought locally. After seeing how these scored on youtube reviews, I bought a pack on a whim and... WOW! I left a LASER level (for those who know, these things chew through batteries so fast its scary) on the other side of the room from me while tiling a floor. After i got to the end I realized i had no way to retrieve the powered on laser, and so I shrugged, saluted the thing, and vowed to come back and grab it the next day when the tile had dried. To my SHOCK, i came back 20 hours later and the laser level still worked and had battery left. Unreal! Ive bare gotten 10 hours total out of other brands, but this product blew my mind. Crazy!

These batteries work great! They last as long, or longer than the Energizer Lithium batteries that I have replaced with these in my Blink cameras. And they cost less.

Worst batteries ever! Some of these were dead on arrival. Others, died after only about 1 week of use (where normal Duracells would last nearly a year). It's too bad my return window is closed since I didn't need the batteries right away. I got 6 more unused batteries left out of a pack of 16 because they kept dying or were dead. I don't know how quickly the leftover ones will last. What a waste of money. UPDATE: The Powerowl crew immediately reached out to me about my unsatisfactory experience. Powerowl's customer service was sincere in wanting to make this right for me. They sent out a new set for me. I tested out every one of the batteries in the new set this time and they all work. None were DOA this time. I'm updating this review from a 1 star now to a 5 star because a bad batch of product can happen to anyone, but I was deeply impressed with Powerowl's service. Not a single time did they ask me to change my review. I'm changing it because I feel they deserved it and won me over.

Life is good in cooler weather. Put them in a Blink camera when temperatures routinely hit mid-90’s and didn’t last a month.

Useless. Severely overcharged on arrival. When these arrived as always I will place them in the charger. It was to my surprise to get a flashing red light. A DMM was able to show me these are at 1.8v which is above the safety range for the charger to attempt to charge them. Apparently rechargeable batteries of these kind are natively at 3.6v but an internal chip is supposed to regulate them at a consistent 1.5v. I am reluctant to return these due to regulations and convenience. I will take the chance and try to run them down to 1.5v in a flashlight and re attempt charging but I am not happy about it. I have bought different brands in the past with mixed results. It is always a toss up on th batch you receive I guess

I buy these lithium batteries all the time for my outdoor Blink cameras. They are such a great value compared to all the name brand ones and work great.

These are AWESOME 1.5V AA batteries! They are *not* rechargeable but they fully and safely replace traditional alkaline batteries -- not only do these lithium batteries have the same 1.5V voltage (which beats the 1.2V found in NiMH rechargeable batteries, whose voltage is too low for many a gadget) but they are leak-free, which is the most important factor in my decision to buy these. As mentioned, these are NOT rechargeable -- you can find affordable rechargeable LiIon AA and AAA batteries which I also bought from this website. But that's okay; I can put these in electronics that I may forget to change the batteries for, such as vintage portable computers (think the Tandy Model 100 or Laser 50) as well as alarm clocks, etc. So far these batteries appear to last a long time, too, so I'm very happy with them and will only buy these instead of alkaline in the future. (Alkaline battery leaks can be toxic.)

I purchased these "expensive" AAA size batteries to replace standard alkaline AAA size batteries I use on low discharge rate devices. Lower cost alkaline batteries work well for devices that you end up replacing the batteries as often as every 2 to 3 years like TV remote controls that are used fairly often. However, for devices that sit unused for extended periods like months or even years at a time, the concern with alkaline batteries is that they have the potential of leaking acid and possibly damaging the battery terminals or the device's printed computerized board (PCB) itself. Lithium batteries in general do NOT leak acid, so Lithium batteries generally do away with the battery acid leakage concern entirely. "Disposable" Lithium batteries in general have a slower self-discharge rate compared to "rechargeable" batteries, so there is still a market for disposable batteries, at least for now. 😀 POWEROWL enjoys a very positive reputation for both performance and longevity. My experience with all my disposable POWEROWL 9V/AA/AAA size batteries has been very positive so far.

Great batteries that last - I use these for my Blink cameras and rarely have to change them.

I know Power Owl from their regular rechargeables, which I've been happy with. These Lithium AA are well priced and seem to last as long as the name brand versions, so I'll keep buying them for my security cameras.

this is a set of 8 lithium batteries, they’re 1.5v, aa size; ordered it for my camera flash use, that required powerful battery for fast recharge time, lithium batteries has advantage over alkaline battery because they maintain full voltage throughout charge life but alkaline battery will drop, it doesn’t make much different for low power device but it’s obvious with high power device like flash batteries came in a paper package, no plastic package to remove, they have a 10 years shelf life, so i’m not worry about getting more for backup tested it got really power output (over 1.8v consistently) i’m really satisfied with this product, would recommend

Battery lasts quite a long time.

Although I’ve replaced the batteries used in most of our household devices and the kid's toys with rechargeable batteries, you can never quite get enough of AA batteries which always come in handy, especially when you urgently need them and don’t have time to recharge another set. The most common devices that drain rapidly are the kid's toys, particularly the kid's RC cars and of course, the multitude of remote controls used for TVs, set-top boxes, speakers and the like, and these batteries by Powerowl seemed a good alternative. In the box, you get 8 long-lasting lithium batteries offering 3000mAh of juice. I’ve so far used these on the Kid’s basketball hoop, which takes 3 double A’s to power the audio and LCD scoreboard and another 2 on the remote for the Soundbar in our living room. So far these are working great and I expect them to last a while considering the power output and the regularity of the usage of these devices. One thing to note, however, is how incredibly light these batteries are, they weigh considerably less than the typical AA batteries, which I’m sure has something to do with them being lithium rather than alkaline. Regardless, as mentioned earlier, it’s always a good idea to have some backup batteries that always come in useful to power devices in case of emergencies, and these batteries from Powerowl seem like a reliable set.
