Outstanding reliability and longevity.
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.

Incredible all-night performance in a high-drain costume
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.

Cost efficient considering how many 'cheap' batteries you get through
Expensive but cost efficient considering how many 'cheap' batteries you get through, especially at Christmas. They last for ages and are perfect for high drain devices like video doorbells etc

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!
