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

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 use these in my Blink cameras and they work as well as the big name brand lithium batteries. They are not rechargeable but last a long time. I would buy again.

I have an extensive fleet of Blink external cameras I have to keep fed, they take 2 x AA batteries, and lithium ones are recommended. The Energizer ones that come with the cameras last on average almost 2 years depending on how often the cameras get triggered (and two years is 100F summers, 0F Winters in Connecticut) so I keep spare batteries to hand. I've had another brand of lithium AA's previously, and frankly I wish I hadn't! The high triggered cameras only lasted 6 months before Blink took them offline, not a great result! So far with these (and this is my second pack of them) they have lasted 18 months, and Blink hasn't complained about battery levels yet. I've found my brand it seems! More expensive than other cheaper options, but quality does always cost a bit more, I'm happy to recommend these!

Update: The Powerowl team was quick to reach out after hearing I had an issue and make it right Pretty disappointed in the quality of these lithium batteries, I was previously using traditional batteries for my smart door lock which ran out after about a month. Not wanting to replace them as often I figured these would be a good alternative, unfortunately they only lasted 2 weeks before dying. For several times the cost of lead acid I expected better :(

Great Lithium option instead of the price for name brand options. They last long, I use them for my security cameras as they require this specific type of battery. I've never had any issues and I've been purchasing them for years.

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!

I use em in my blink outside camera. They last longer than regular batteries.

Research supports the claim that these batteries are long-lasting. That is why I bought them. They are NOT rechargeable, though I thought all lithium batteries were rechargeable. I expect these batteries will serve me well for a long time.

These last for months on my cellular trail cameras that send me at least one picture every 2 hours. They also worked all winter in the minus 30 degrees celsius.

The POWEROWL AA Batteries, 24 pack are very effective and seem high capacity as described. Used in small alarm clock daily and in facial hair trimmer occasionally, and toothbrush frequently, all over 60 days and power still present. Definitely better then dollar store batteries and seem just as effective as big brand names, and at a super lower price for larger 24 pack, more then personally needed which all may never be used, and if need, just swap out another, and at the time about 7 dollars less then coppertop brand on promo price for large 18 pack. Powerowl seems a hoot win battery.

Long-lasting and dependable in my tech gadgets I’ve been using these in my tech gadgets and have been really pleased with how long they last. They’ve proved dependable, and the quality has been good. Battery life is what stands out most for me. Very happy with these and would buy them again.

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

Forget alkaline and keep ordering these ones. Almost 2x run time for same price.
