Ultimate Lithium AA Batteries, World's Longest Lasting Battery for High-Tech Devices (4 Each), Black (EVEL91BP4)

Great price, last a long time.

I always stock up when low or on sale!

These are definitely great for certain electronics where you need the lithium battery over rechargeable or alkaline. I use these in my wireless thermostat for my AC and it’s great. Before I was going through alkaline batteries like once a month and rechargeable just didn’t work. These last easily 6+ months

As many reviewers say, it is important to use these for the right job. Simply putting these in a TV remote would be a complete waste of money due to thier price. However, when used in an apllication that requires increased performance, these batteries are completely worth the price you pay. Mostly, I use them for flashlights for camping and other tasks around the house. They not only make my flashlights last longer, they increase the brightness and will not fail in freezing temperatures. I own some pretty expensive flashlights also. The lithiums are far less likely explode or leak like alkaline have been known to do. It has happened to me and ruined a flashlight on me. That being said, I recommend these for your high-end electronics like digital cameras or two-way radios and the like. They will perform better and will not be ruined by a battery malfunction. The other great thing for the camping aspect is the lightweight of the batteries themselves. This allows me to pack them into my system and not worry about weight as they feel seemingly hollow, almost cheaply light. I highly recommend the Powerpax battery caddy sold here on amazon for storage in camera bags or your camping system. They keep them from coliding with each other and getting damaged. You can seem my in-depth review on these items as well to gain an idea of how well they function. You can also buy these in bulk as the shelf life is 15-16 years as advertised. I can not vouch for this personally but it is an intriguing idea for sure. Also, I beleive the 12 packs sold in Sams Club are the best deal I've found as each battery came to be $1.67 a piece. However, sometimes the prices on amazon drop and they become a better deal and vice versa. Overall, I highly recommend these batteries for those tasks that demand performance. They are worth the price and will keep your expensive electronics safer.

Good value. Lasts almost as long as Duracell but costs a little less. Some of the off brand batteries don’t last very long, so the appeal of low price goes away quickly.

These batteries are NOT cheap. However, they are needed for my personal flashlight that could allow a 747 to land in the amazon jungle safely. Finding these online is always a trick but as they are needed, I will purchase again.

These are the only batteries that work with the blink doorbell

Energizer ultimate lithium are my go to double AA batteries. Excellent product.

If you have an outdoor weather station or sensor like many smart hone devices do now a days you need to use lithium batteries in it because they’re good down to -20°C. It would be great if they were rechargeable but they do last quite awhile so I’ll give them a pass on that.

In my experience, finding reliable batteries can sometimes feel like a wild goose chase, but I must say, these Energizer AA Lithium Batteries have been game-changers for me. I use them exclusively for our Nest smoke protectors, and honestly, I couldn’t be happier with their performance.For starters, the battery life is phenomenal. It’s not just me saying this as a casual user; I've genuinely noticed how infrequently I need to replace them. That's a relief when it comes to smoke detectors, where ensuring consistent power is non-negotiable for our family's safety. I mean, who wants to be jolted awake at 3 a.m. by that dreaded low-battery chirp? Not me.What’s more, they seem unbothered by Michigan's notoriously fluctuating temperatures. Whether it's a crisp winter night or a sweltering summer day, these batteries just keep delivering, which in my book, makes them super reliable.Another thing I appreciate is their lightweight design. Okay, I'll admit, batteries aren't something you carry around all day, but it's still a neat perk when handling them for installation.All in all, I tend to think these Energizer AA Lithium Batteries are a solid investment if you’re after peace of mind and durability. They might initially seem a tad pricier compared to regular alkaline ones, but their extended lifespan easily offsets that cost. We put trust in them, especially for critical devices like our smoke protectors, and I’d recommend them without hesitation to anyone looking for trustworthy power solutions. Seriously, they provide exactly the kind of reliability we all want in our homes.
