EnergizerUltimate Lithium AAA Batteries (4 Pack), Lithium Triple A Batteries

Long-lasting power: Energizer AAA lithium batteries typically last longer than standard alkaline AAA batteries. They are designed to provide a consistent and reliable power source for your devices.Lightweight and compact: Lithium batteries are lightweight and have a compact design, making them suitable for small and portable devices such as remote controls, digital cameras, flashlights, and more.Wide temperature range: Lithium batteries perform well in extreme temperatures, both hot and cold. They are ideal for outdoor use and devices that may be exposed to varying weather conditions.Extended shelf life: Energizer AAA lithium batteries have a longer shelf life compared to alkaline batteries, so they are a good choice for devices that are infrequently used or stored for extended periods.Leak-resistant: These batteries are less prone to leakage compared to alkaline batteries, which can help protect your devices from damage.High voltage: Lithium batteries provide a stable and relatively high voltage throughout their lifespan, which is important for the proper operation of many devices.Keep in mind that while Energizer AAA lithium batteries offer several advantages, they are typically more expensive than standard alkaline batteries. The choice between lithium and alkaline batteries depends on your specific needs, the devices you use, and your budget.

These batteries have great longevity. I use them both for devices that are used daily and especially for items that may sit stagnant for a while. That way when I come back to them, they are still working as good as the day I installed them.

I used these to replace alkaline batteries in a LED flashlight. Slightly higher voltage, so brighter light.

I used these batteries on a graphing calculator that accepts only 4 AAA batteries. I purchased these since they don't leak, unlike alkaline batteries, and because I don't want to remove them from my calculator since it is a hassle to remove it back and forth and removing it would corrupt save settings on my calculator.I do not regret purchasing these batteries, and I wish I've purchased them earlier for critical devices that I don't want to get ruined by leaking alkaline batteries.

Must have for temp sensors inside of a refrigerator or freezer

Best battery for this type

Works great

Really expensive (and super light weight compared to regular and rechargeable batteries - THESE ARE NOT RECHARGABLE).For some high power tech, camera, digital products - its worth it.Not good for environment, but do the calculous - they take the place of 3-4 or more regular batteries
