10 pcs Energizer Lithium CR123A 3V Photo Lithium Batteries

got to replace batteries in AED ! works great

Normally I buy Surefire primary CR123a batteries, well aware that most of the big brand name CR123a cells are manufactured by Panasonic., but bought these Energizers this time to kick it's tires.To test these, I took two identical Surefire Invictus flashlights. I put in three Surefire cells in one and three of these Energizers in the other and set both magnetic control rings to one back-click from full power to see which battery lasted the longest.Over the years I've found this side by side test to be a good tell all to determine the best cell in the runtime department. (it is however a bit wasteful to waste six CR123a cells and put a bit of wear and tear on the lights themselves, but its not a performance test I run often, combined with the fact that Surefire uses a proprietary premium thermal interface material & proper heatsinking, it can be abused some. (I have a big tube of it in my shop, it's approved for NASA use as well)Surefire doesn't cut corners, and that's why their products are a bit pricey, but you can count on them when it counts.)In the end the performance run time of the Energizers was nearly identical to freshly bought Surefire primary batteries. I suspected this would be the outcome. I'd surely buy them again now that I know it's tit for tat with Surefire primary cells.

Worked perfectly.

I do prefer Energizer batteries but I have been noticing that they seem to be wearing out much faster then when I first started purchasing them! They DO work in my Arlo cameras but I am relieved that my new Arlos have been updated to use USB charging instead of needing to continually replace these batteries. The USB charge will save me a lot of money on batteries!

I've bought this 10 pack 3 times now for my flashlight I use for work. I've never had an issue with these batteries at all. I'm using 2 of them at a time in a Streamlight Scorpion HL light, and at max power they will last about 2 hours if left on, but I don't know anyone who would leave this light on at max power for that long first off.I only use mine at low power for rounds, and it's on maybe 5-10 minutes at a time, so a 10 pack of these batteries will last me about 6 months. Considering 1 3v battery at the local store is 15 bucks.

Long lasting.

I have a wireless home alarm system. My motion detectors and smoke detectors each use an Energizer Lithium CR123A Lithium Battery. This bulk pack of batteries is half the price of the same battery in my local Big Box store.

As shipped by MYBATTERYSUPPLIER, the items arrived as loose items, not in a sealed Energizer product package.The use-by date on the batteries was 03-2020. A set of Energizer CR123 batteries recently purchased from a grocery store have use-by dates 03-2022.It can be reasonably deduced the MYBATTERYSUPPLIER batteries have been sitting on a shelf for two years.Well, hopefully that is all they have been doing for the past two years.But these batteries are considerably less-expensive.Bottom line, the batteries seem ok, but certainly would not want to rely on them for any critical uses.
