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

Bought a box last year for use in Ultraloq smart door locks. Front and back door lock batteries were changed Feb 7 2025 and today, Feb 12 2026 the front door finally hit low battery. Best part is I've still got eight batteries left from that first order which means I won't need to buy again till 2027. Batteries are too damn good for a subscription but I'm definitely saving these

Great batteries! I'm always needing batteries for a remote, a mouse, a clock, or something else around the house. Seems like I was buying and throwing away batteries constantly so I decided to try these versus my usual Energizers. They seem to last just as long, maybe longer for a fraction of the price.

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

After watching Project Farm's YouTube review, I decided to give these batteries a try. Unfortunately, my experience has been disappointing. Out of the 16 batteries I've used, six were completely non-functional. This failure rate is far higher than expected, which makes me wonder if I received a defective batch. While the positive reviews and third-party testing gave me high hopes, my personal experience has been underwhelming. Updates: This Seller is fantastic and super friendly. They reached out to me and offered to either provide a refund or receive a new set of batteries. Still disappointed with the batteries that were dead on arrival, but those things happen from time to time. I recommend this seller and will try these batteries again.

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!

Lithium non-rechargeable batteries are the ultimate power source for my digital cameras and motor driven film cameras. Equal to others such as Duracell or Energizer.

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.

I bought this 16-pack of POWEROWL Lithium AA batteries for a mix of home devices—mainly remotes, wireless gadgets, and a couple of high-drain flashlights—and I’m really impressed so far. The quality is excellent. They feel solid and reliable, and every battery has worked perfectly out of the pack. The size is standard and fits all of my devices with no issues, and the battery size is clearly labeled, which is helpful when sorting through drawers full of random batteries. One thing I didn’t expect was how well these perform in devices that depend on brightness, like my LED flashlight. The light stays strong and consistent even after extended use, which tells me the voltage is staying steady. Longevity is where these really shine—I haven’t had to swap any of them out yet, even after weeks of daily use. While these aren’t rechargeable, the fact that they last so long makes up for it in convenience. As for charge speed, it’s kind of a bonus: since these are lithium and come fully charged, you get instant, full power right away. No waiting around like with rechargeables.

Excellent lithium battery

Have re ordered a few times , good battery life as I use them for my door bell ring , good quality

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

Works as advertised, kept an Ecowit powered over cold winter with snow and ice.

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.
