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 LongevityOne 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 ReliableAnother 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 TemperaturesThe 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 SafeSafety 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 PackThe 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 ThoughtsOverall, the Energizer AA Batteries, Ultimate Lithium, 4 Pack is a fantastic choice for anyone who needs reliable, long-lasting power. Their impressive lifespan, lightweight design, and excellent performance in outdoor and indoor conditions make them a standout product. 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.

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.

These batteries are noticeably longer lasting than competitors' batteries.I use rechargeable batteries, but I always use these for my Blink cameras. Any other batteries used in the Blink cameras last a FRACTION of the time that these do, therefore, these are my go-to if long battery life is required!My only complaint with these is the price, but you get what you pay for!

These Energizer AA batteries are exactly what you'd expect from a trusted brand. I use them in a variety of household devices—TV remotes, wireless mice, wall clocks, and even kids' toys—and they last a long time compared to some cheaper alternatives.The pack of 4 is perfect for keeping a few spares around, and the packaging is easy to open without needing scissors (a small but appreciated detail!). I’ve had no issues with leakage or dud batteries.Definitely worth the price for the performance and peace of mind. Energizer continues to be my go-to brand for batteries.

Initially I thought why on earth is the Energizer lithium to be recommended for my external doorbell/camera. After using I replaced with the best 'non' lithium battery (Duracell) which I have used consistently (excellent for non lithium items). The results were unbelievable. The Duracell lasted a few weeks, while the Energizer lithium lasted almost 3months. I think the cold was a major problem for the Duracell, while the Energizer was longer lasting and immune to the cold. Until Duracell or another manufacturer produce a lithium battery there is no other choice (as of Nov 2024) as the longevity, protection from the cold or pure power means nothing comes remotely close to the performance of this battery.
