Energizer Ultimate Lithium AA Batteries (4 Pack) - World's Longest Lasting Double A Battery - Ideal For High Drain Devices - 100% Recyclable Plastic Free Packaging - 25 Year Shelf Life

I purchased these batteries for my Blink Outdoor camera system, as they were the ones it came with initially, and I have been extremely impressed with their performance. I currently have eight Blink cameras, and I now use these batteries in all of them. I’ve tried other lithium batteries before, but none have matched the consistency, reliability, and long-lasting power of these Energizer ones. Each AA battery weighs just 33 grams, making them noticeably lighter than standard alkalines, which is helpful when using multiple cameras or other portable devices. With a capacity of 3000 mAh, they provide significantly more energy than standard alkaline AA batteries, which typically range from 2000–2500 mAh. This higher capacity means they can deliver longer runtime, particularly in high-drain devices, so I don’t have to replace them frequently. In my Blink cameras, they have lasted up to six months even with heavy use, which is exactly what I need, as I often use the live view feature. The description states that they operate effectively across a wide temperature range, from -40°C to +60°C, so they can handle both cold winters and hot summers without issue. While I haven’t personally tested them at those extremes, they have been in my Blink cameras in direct sunlight on the hottest days of the year and performed flawlessly. They haven’t experienced the cold of winter yet, but if they can handle -40°C, it won’t be a problem here in the UK. I’ve had no issues with leaks or device problems, and the batteries deliver consistent, reliable power throughout their life. Although these are more expensive upfront than regular alkalines at £9.25 for a 4 pack, they are excellent value for anyone needing dependable, long-lasting power. I normally try to wait until they are on offer, as even with their longevity, buying enough for all eight of my Blink cameras can still hurt the wallet. However, having been stung before by cheaper lithium batteries that barely lasted a month, I’d rather invest in quality and peace of mind, which is exactly what you get from Energizer. Highly recommended! Thank you for taking the time to read my review. I hope that you found it helpful and that it assists you in your decision-making. I try to be as honest and fair as possible, as those have always been the reviews that helped me the most.

Great batteries, shame about the price, long shelf life, don't sulphate when forgotten. Powerful enough for the most reliable, and demanding of purposes. Thank you.

These are genuinely lithium batteries and perform well. Used in higher-drain devices with no issues so far. Expensive, but reliable.

The Energizer Ultimate Lithium AA Batteries (4 Pack) represent great value for money. I could have ended the review right there. However, I can tell you that you cannot get these batteries in a bricks-and-mortar retail outlet. Nope! I looked into big supermarket chains to no avail. I looked into electronics shops to no avail. I don't know why these lithium batteries aren't readily available in physical retail outlets, but I am glad to have been able to get them from Amazon! As you might know, these lithium AA batteries are a must for video doorbells and any other device requiring consistent and long-lasting power. The product has a 25-year shelf life; the packaging is good... It's a solid product. I did not see any signs of leakage as you can get with some other brands. Usually leakage occurs over time when stored in less than optimal conditions. Batteries can even lose power over time in storage. But these Energizer Ultimate Lithium AA Batteries (4 Pack) were perfect. Insert and be rest assured that these batteries will last a long time. Recommended.

Best batteries

I recently purchased the Energizer Ultimate Lithium AA Batteries to use with my MetaQuest3's controllers, and I must say, they've exceeded my expectations in several key areas. Usage and Performance: These batteries have lasted significantly longer than the ones that came with the controllers and even outperformed another reputable brand I had previously purchased. For anyone using high-drain devices like VR controllers, these are a solid choice. I found they lasted 2-3 times longer than standard alkaline batteries, which means fewer battery changes and a more seamless experience. Design and Packaging: The batteries come in a recyclable cardboard-backed plastic holder, which I appreciated as it was both secure and environmentally friendly. The packaging was easy to open, yet it kept the batteries well-protected until I needed them. Reliability: So far, these batteries have been incredibly reliable. They haven't leaked, which gives me confidence that they won't damage my controllers or cause any unwanted mess. Being lithium-based, they provide consistent power throughout their use, and I feel secure in knowing that these batteries are a safe choice for my devices. Value for Money: While these batteries are a bit more expensive upfront compared to regular alkalines, the longer lifespan actually makes them more cost-effective in the long run. I believe they offer excellent value for money, especially for devices that require consistent and long-lasting power. Additional Information: One important note; these batteries are *NOT* rechargeable. Although they contain lithium, they are not the lithium-ion type that can be recharged. Instead, they use lithium manganese dioxide (Li-MnO2) or lithium iron disulphide (Li-FeS2), which are optimized for a lower voltage and are not suitable for rechargeable applications. The listing does mention this, but it’s in small print, so I wanted to highlight it here for anyone who might, like me, assume they are rechargeable. Knowing this beforehand is important for making an informed decision. Overall Satisfaction: I’m giving these batteries a 5/5. Despite my initial assumption that they were rechargeable, which they are not (and the listing does state this to be fair), their performance in my MetaQuest3 controllers has been outstanding. They’ve lasted much longer than any alkaline batteries I’ve used before, and I’m overall very satisfied with this purchase.

I’ve been really impressed with the Energizer Ultimate Lithium batteries. They last noticeably longer than standard batteries, especially in high-drain devices like cameras, smart doorbells, and gaming controllers. Even after heavy use, they keep going far longer than I expected. They’re also lightweight, reliable, and perform really well in colder temperatures where normal batteries tend to struggle. I like having a pack stored away too because they have an excellent shelf life. A bit more expensive than regular batteries, but definitely worth it for the performance and longevity. Highly recommended for devices you rely on every day!

I tested these batteries in an inflatable Halloween costume at a party and wore it for over 5 hours straight. I wanted to see if they really lived up to the “world’s longest lasting” claim — and they absolutely did. What I noticed: Full inflation all night: The costume stayed fully inflated with constant movement, even while dancing and mingling Consistent power: No drop in performance; the fan never slowed down Reliable & clean: Batteries fit easily, no leaks, no fuss Longevity: Even after the party, there was still energy left for future use Minor drawback: They’re more expensive than regular AA batteries, but considering the performance and peace of mind, the cost is easily justified. Why I’d recommend them: Perfect for high-drain devices like inflatable costumes, remote toys, cameras, and flashlights Gives consistent energy for long events — no mid-party panic Durable, dependable, and worry-free After using them, I can confidently say these are worth the extra investment. If you want batteries that last all evening (or beyond) without any drop in performance, these deliver exactly as promised. I’ll definitely be keeping a few packs on hand for every holiday and high-drain gadget.

Prima di acquistare le mie telecamere Blink Outdoor, non ero a conoscenza di queste pile, ma devo dire che si sono rivelate una scoperta eccezionale. Sono letteralmente fuori dal comune rispetto alle classiche batterie che si trovano in commercio. La loro caratteristica principale è che sono veramente ultra longeve. È vero, all'acquisto costano un po' di più rispetto alle pile standard, ma vi assicuro che ne vale assolutamente la pena perché durano tantissimo e vi evitano la scocciatura di dover smontare i dispositivi per fare il cambio ogni due per tre. Un piccolo consiglio per chi vuole acquistarle: sfruttate l'abbonamento periodico di Amazon (il programma "Iscriviti e Risparmia"). In questo modo avrete sempre a disposizione le batterie quando vi servono e, soprattutto, risparmierete sempre sul prezzo finale. Prodotto eccellente che risolve il problema dell'autonomia. Consigliatissime!

Here’s your review optimized for Amazon: 5 Stars – The Only Batteries You Should Use for Your Ring Cameras 🔋📹 If you’re using Ring security cameras, stop looking and just buy these batteries. Seriously, don’t cheap out or experiment with alternatives—these are 100% the right choice. I’ve been amazed by how long they last. My front door camera powered through from July to January on one set, and that’s with constant motion alerts (thanks, windy days!). My backyard camera is still going strong because it records less often. For something you only need to buy once or twice a year, these batteries are totally worth it. They last longer, save you the hassle of frequent replacements, and keep your cameras running without any hiccups. Highly recommend for anyone with Ring or Blink cameras—you won’t regret it!

Piles au lithium, dédiées pour mon usage aux caméras Blink Outdoor, qui lui assurent une durée d'au moins 2 ans (selon les paramètres de déclenchement). Un peu plus chères que des alcalines simples, mais tellement plus durables

Son unas baterías excelentes, para el uso que les doy, son quizás algo más caras, pero es normal, son de calidad premium.la duración es brutal , justo hace unos días utilizamos el segundo juego de recambio de las dos primeras y cuando toque , volveré a comprar este mismo producto , de nuevo, no me la quiero jugar. Recomendable 100%

It is my third purchase since last 15 years.
