POWEROWL Lithium Batteries AA 16 Pack, High Capacity 1.5V Double A Battery Long Lasting Power for High-Tech Devices

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 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.)

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.

Batteries are a good value for the price.

Defective products! These batteries have electronic voltage regulator integrated. (A new lithium battery typically has around 1.6 - 1.65 volts with no load.) They also quite apparently have a manufacturing defect build in! I found out that quite a few people and reviews by many other buyers report the same issues. Low power consumption devices like a wall clock that would run over a year on an alkaline battery and up to 4 years on a lithium battery stopped after just 1 1/2 months! I have the habit of writing a "new battery" date sticker when I insert new batteries. this began to reveal very quickly that PowerOwl batteries have a defect and rapidly lose their capacity, faster than a conventional Zink/carbon battery! I purchased in bulk a year ago, spring 2025, AA & AAA based on the recommendations. PowerOwl batteries ordered year ago which should have a shelf life of up to 10 years are all dead or have very low voltage/capacity. By comparison older alkaline and even zinc/carbon batteries I have are still good! Worse is I found out (too late) that when you measure the voltage you get your nominal 1.6 - 1.65 volts on the terminals but the measurement is deceptive as it is a open no-load measurement. the 2nd they're under load i.e. in a flashlight, turning it on the voltage collapses! I had a flashlight fail and I inserted from my stock new AA PowerOwls. The flashlight did not power up. The batteries measured were "good" so I thought the flashlight is defective and tossed it out. Then another device suddenly stopped working and I replaced the batteries but it would not restart. My office wall clock stopped but I recalled that I placed a new battery to that wall clock in early March!. the date sticker on it confirmed that! (That clock usually runs over 4 years from a lithium battery.) The battery measured under the "clock drive" 350 mV when taken out and measured it showed 1.55 volts!. I will request a refund! I was sold a defective product!

They work well.

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. I use the. Fir my doorbell camera. My only complaint is they don't last very long. Have to change them out every couple weeks

The best batteries I've purchased for my blink outdoor 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

Long lasting!

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.

Excellent lithium battery
