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.

I recently purchased the Energizer AA Batteries, Ultimate Lithium, 4 Pack, and I must say that I am thoroughly impressed with their performance. As someone who relies heavily on AA batteries for a variety of devices around the house, these batteries have exceeded my expectations in every way. Unmatched Longevity One of the standout features of these batteries is their incredible longevity. They truly live up to the "Ultimate Lithium" name. I've used them in high-drain devices such as digital cameras, handheld gaming consoles, and smart home devices, and they last significantly longer than any other AA batteries I've used before. This longevity not only saves me money in the long run but also ensures that my devices are always ready to go when I need them. Lightweight and Reliable Another advantage of these batteries is their lightweight design. Despite their extended life, they are lighter than traditional alkaline batteries, making them perfect for portable devices. This feature is particularly beneficial for camping trips and travel, where every ounce counts, and you don't want to be weighed down by heavy batteries. Exceptional Performance in Extreme Temperatures The Energizer Ultimate Lithium batteries also perform exceptionally well in extreme temperatures. I've used them in both hot and cold environments without any noticeable drop in performance. This makes them an ideal choice for outdoor enthusiasts who need reliable power in challenging conditions. Leak-Proof and Safe Safety is always a concern with batteries, and Energizer has addressed this with their leak-proof design. I have peace of mind knowing that these batteries won't damage my devices or create a mess. This reliability is especially important for expensive electronics that I want to keep in perfect condition. Great Value Pack The 4-pack option offers great value for money, allowing me to stock up and have spare batteries on hand whenever needed. The packaging is also easy to open and store, making it convenient for both home and travel use. Final Thoughts Overall, the Energizer AA Batteries, Ultimate Lithium, 4 Pack is a fantastic choice for anyone who needs reliable, long-lasting power.

Whether you're powering everyday household items or demanding electronic devices, these batteries are a top-tier option that won't disappoint. I highly recommend them to anyone looking for the best AA batteries on the market.

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

Good quality pack of batteries, lasts long and lightweight batteries that are great for my Logitech mouse

So far, these Energizer Lithium AAs have been great. They seem to hold their charge really well, even in devices that tend to drain batteries quickly. I’ve used them in a few gadgets around the house and haven’t had to replace them yet. That said, I did run into an odd issue when I tried using them in a Yale smart door lock. For some reason, they caused Bluetooth connection problems that went away as soon as I switched to regular alkaline batteries. Not sure why that happened — could be something to do with the device rather than the batteries themselves. Outside of that one hiccup, these are solid batteries. They’re lightweight, long-lasting, and definitely worth it for most high-drain devices.

Great quality and fantastic endurance.

Pile de marque donc longévité.

Great long-lasting Lithium AAA's, No leaks, temperature not an issue. Made in Singapore (Not Spain).

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!

El producto es una maravilla, pero jamás me enviaron las pilas pese a que me las cobraron, no le compren nada a Rarewaves-MX es un fraude. Atte. José Contreras.

Las pilas son las recomendadas para la camara pues son de larga duracion, es por lo que no he dudado en la compra.
