Review: Dependable and Long-Lasting Lithium Batteries - 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.

## Questions & Answers

**Q: Best AAA LONG LASING battery ?**
A: First I bought AA not AAA.  I use these in Trail Cameras which on pic settings I use take three pics in a set and I have set for 5 Megapixels .  Camera circuits power a detection circuit also and pointed into the woods if winds blow will shoot limb movement (repeated every 3 seconds). I have one set in one camera that has taken over 60000 pics and still show full on the battery check window.  Looks like they are going to last longer than regular Alkaline batteries plus they also have a very long shelf life.  In another camera set for 45 second AVIs plus one pic, Ive had 2000 taken then showing dead. However only one battery was actually dead,(or nearly so) replaced it and got another 2000 pics and AVIs. These pics and AVIs were taken in fairly cold weather too.  So they do last longer for my use in those cameras, which is the type of application they are designed for.  They aren't intended for flashlight use etc. but high drain rapid repeat use.  For my trail Cameras I will continue to use them, especially during cold weather. For general flashlight use I use rechargable or Alkaline batteries. Hope this helps.

**Q: Can you use the energizer  AA lithium 9x batteries in a TV remote, I had a Philips long life battery that came with the remote and it lasted 3 yrs.**
A: Yes, but it is a waste of money. In low-drain devices such as TV remotes, ordinary alkaline batteries will last just as long as those lithium AA batteries - at a fraction of the cost.

**Q: Whst is the experation date?**
A: Look carefully on the package or battery? I use them in my automatic waterer..they lasted over a year..2 seasons.. watering  2X daily and still going..so maybe longer.  Ask the Company??

**Q: What type of charger do I need for these?**
A: Sorry, no charger, just garbage when they run down.
