Single-use AAA Lithium Batteries

I am burning through AAA batteries on my TV like crazy (apparently 4326 clicks a day is a little much!) so I looked around for something that would last. I heard about POWEROWL from Project Farm on Youtube. This guy tests everything on his own with no sponsors and he gave POWEROWL a good recommendation. So far I am impressed - they have kept their charge WAY longer than other brands and, as a side note, they come in a really cute compact box instead of all that nuisance plastic. They should be more widely known - a good product at a good price!

Update 5/6/26: The seller contacted me and sent me replacement batteries. Hopefully the new set performs better. Original review: I compared these directly to Voniko AAA alkaline batteries using my Wyze scale. The Voniko batteries lasted 4 months and 8 days, while these Powerowl batteries only lasted 2 months and 7 days under the same conditions. Based on that difference in lifespan and the big price gap, I wouldn’t purchase these again.

I have been very happy with PowerOwl lithium batteries. They work perfectly, last a long time with all the other benefits of lithium (work in the cold, hold steady power output till the end, etc) and the price here is much better than store bought lithiums. Love them.

These batteries work great. I don't expect much out of AAA batteries because they typically go into things like remote controls and they all last a really long time. But with these being PowerOwl and having a black label I expected them to be just like my other rechargeable, black labelled, AA PowerOwl batteries and they were not. The product never said it was rechargeable, and it was my oversight that was the problem, but be aware of this.

Much better service from these than regular AAA. More economical and less trouble changing batteries.

1 - star, although I do have a cautionary note, not necessarily because of the product (POWEROWL Lithium Batteries AAA High Capacity Long Lasting, 1.5V Triple A Battery for High-Tech Devices - 8 Pack), but because the Amazon purchase experience led me to buying these NON-RECHARGEABLE disposable batteries, when I wanted to buy RECHARGEABLE batteries. The bad: 1) The cautionary note is that I noticed that the positive battery tip is smaller than what I thought was the standardized tip-size found on every AAA battery that I've seen/used before. This sizing discrepancy might cause contact issues in sloppily designed/built devices that count on a larger tip to make good contact. So, beware. 2) Regarding the purchase experience: a) After sorting by "Avg. customer review, these "Amazon Recommended" NON-RECHARGEABLE disposable batteries showed up at the top of my Amazon search results for "Rechargeable Li ion 1.5V AAA batteries". Note that my first search term was "Rechargeable". b) It's easy to overlook the one place, i.e., one photo, where it's noted that these batteries are actually non-rechargeable. (I found the photo when I was trying to figure out how I bought something I did not want.) It's not noted in the description anywhere I found that these batteries are disposable. To be honest, nor is it stated anywhere that they are rechargeable. So, my bad assuming, because I searched for rechargeable batteries, that the top battery in my search results, which was also "Amazon Recommended", would be rechargeable. c) Amazon conflates user reviews of multiple POWEROWL battery products, e.g. rechargeable and non-rechargeable and AA and AAA sizes, into the user reviews for this single product. d) Amazon review's Ideas suggestions for this product review laughably included the prompt "Why did you pick this product vs others?" and the phrase "Rechargeable battery". Note that I did respond to the prompt and used the suggested phrase, but I'm guessing, probably not in the manner intended. To be fair and balanced, on the plus side: 1) Next day delivery happened as promised. 2) The Amazon delivery person was friendly when we exchanged greetings as I was outside tossing a ball for the dog when he came by. 3) Packaging was in good shape. The batteries are shrink-wrapped in sets of four. The batteries all appear to be in good shape, no bulging, not leaking. 4) Two of these batteries are now in my Fire TV Cube's controller and they're working fine. We'll see how long they last. Conclusion: Even though I feel I overpaid for disposable batteries, it's not worth my time to try to get a $10 refund and order the rechargeable batteries that I originally wanted. Over the next few years, I'll throw eight (8) more disposable AAA batteries into my electronics recycling bin. When this supply is exhausted, I'll try again to act in a more ecologically responsible manner.

I did research and found out that lithium batteries for exceed alkaline batteries for the money. I found this battery to be the best out there!

First, a disclaimer: I haven't had these anywhere near long enough to speak to their endurance. But going by the very favorable reviews, I took the chance. They arrived very quick, and I actually ordered a 16-cell package of AA'S. The AAA cells came in at 1.81 volts, the AA'S registered 1.79 volts. I checked against some Eveready Ultimate Lithium cells that I've had for about a year, but otherwise new & unused. They showed 1.76 volts. So, the Powerowl appears to be right about where you'd want them to be. The only negative, if even that, is the 10-year shelf life versus the 25+ years for the Eveready's.

Excellent lifespan with TV remotes

I watched Project farm video about lithium batteries and one of the criteria for buying these was their alleged low temperature performance. I've put them into the temperature sensor in my freezer, at around -4°, but they lasted only a few weeks under those conditions. The sensor reports 100% charge and then they abruptly discharge over a course of a few days.

Tel que décrit. Elles fonctionnent.

Good set of batteries for my outdoor thermometer. They withstand cold Canadian winter temperatures.

These did last an hour. Tried it on my bath scale, tried it on my food scale. They both said "low battery".
