Energizer L92BP-4 Ultimate Lithium AAA Batteries, World’s Longest-Lasting AAA Battery in High-Tech Devices (4 Pack)

I have been buying these for quite a few years now. I mainly use them for my flashlight. They work very well and last quite awhile.Amazon has the best prices and a good selection.I am now seeing other rechargeable batteries coming out, will have to compare them. Probably better for the environment to recharge instead of throwing away. 5🌟’s for now.

These are outstanding batteries, if becoming hard to find in retail stores, because they last so long in continuous use, so unit sales are slow!Far more economical than alkaline or "advanced" formula replaceable batteriesI use these "Ultimates" in a medical device (pump) because of their outstanding longevity, reliability, extreme power density, and superior power curve characteristics as compared to all other types of conventional disposable (AAA to D) batteries.No more limping along with low battery alarms and limited (power-conserving) functionality for days, as with worn-out alkalines whose voltage slowly fades away along with the current. (Think of a dying flashlight with which you had to put up continuously for a couple of days!)Full power (voltage) persists until just hours before collapse when used in low-but-constant-drain electronic applications. If these batteries have charge left, they act just like a new battery. When they are out of juice, they just stop, with just enough warning to grab a new battery. (Think of an engine running out of fuel.)These are what conventional (non-specialty) batteries always should have been!

Fat shipping, decent price on these type batteries.

Great batteries I think cGreat batteries

I bought these batteries thinking they where rechargable, but they aren't!These batteries lasted a very long time, I would say about 4-6x longer than my rechargeable batteries, in my ebook reader.Pro's:Long enduranceHigh power outputExcellent for both high power devices (like digital camera's or flash) as low power devices (clock or ebook reader).Cons:Non-rechargableDon't last as long as they mention on the package (4-6x not 8x longer than rechargeables, and about 2x longer than Duracell batteries)Conclusion:I would never buy these batteries for the sole reason that they are non rechargable.Otherwise they are excellent for small electronic devices like clocks and small portable radio's and ebook readers.For high power devices, though these batteries are excellent, I would especially recommend to get rechargeables!

These are economical because they last a long time

Long lasting and easy convenient recharge via the 4-way USB-C that they give you. I needed 1.5v for my quest controllers, and they do the job just fine.

They have a long shelf life and last longer than regular batteries when in use.Good price too.
