DURNERGY CR123A Lithium Batteries 12 Pack 3 Volt 10 Year Shelf Life High Power 123A Battery Compatible with CR17345, CR17335

Pretty long shelf-life,(10 years) so if you got flashlights, these are worth the money.

They are batteries. Worked just fine

Works great, batteries are so exspensive

There are more brands of batteries out there now than ever before, and it's sometimes hard to decide whose to buy. I'm happy with these Durnergy 3v Lithium CR123A ones. They appear clean and well-made (with one exception noted below), and they check out from a voltage standpoint. They advertise a 10-yesr shelf life like most lithium batteries, but I'm a little disappointed they don't show an expiration date like most batteries these days. If I have these batteries for a long time, it would be reassuring to check and find they still have 5 more years of life, for instance. And the exp date also is an insight into how old they are when received. So for now I'll just date them with a marker and hope they weren't years into their shelf life when delivered to me. I was also disappointed to find one of the batteries damaged (see photo). It somehow got a dent during some phase of manufacturing or packaging. It checks out fine on my multimeter, though, so I'll still use it. I'm deducting a star for the lack of expiration labeling and the dented battery, but otherwise they should be good.

Lasted longer than I expected. Great value.

I don't know what to say except they work. I have used it intermittently for a while now in my surefire flashlight and they seem to last as long as the big name brands. I haven't replaced the first set yet so I am pretty happy with that. They fit good and work just like they should. No complaints.

Last a long time!

These batteries are horrible. The first 4 lasted 2 weeks. I replaced them and the CO2 detector immediately said low battery. Do not order them. Spend the money and get a brand name battery….it could save your life.

6 months of low usage in 5 Arlo cameras (camera on, alarm off) compared to 2 month with rechargeable batteries. This is a good value point, especially when they go on sale (once a year or so).

These CR123A batteries are exactly what I needed for my security sensors. They fit perfectly and there are no awkward gaps or loose contacts. Great value, durable build, and reliable performance. I’m so satisfied that I’ll definitely buy this pack again. What I like: The fit is spot-on for my sensors—no wiggle, no misfires. Battery life has been good so far; they’ve lasted longer than a few cheaper alternatives I’ve tried. No complaints about the build or quality—they feel solid and consistent. Pack value is good: getting 12 batteries means I have spares ready, so I’m less worried about sensors going dead unexpectedly. What to keep in mind: These are non-rechargeable lithium batteries, so be sure to recycle them properly. In very cold weather, performance can dip a bit (like many lithium batteries), but still acceptable in my setup. Bottom line: If you’re running devices that use CR123A batteries—security sensors, flashlights, etc.—this pack is a dependable choice. Good value, dependable fit, nice long life.

Bonne piles

Very good, positively surprised! I use these battery size for a automatic door locker for my front door so I know exactly what to expect in terms of durability. Historically, I have been needing to replace the batteries monthly (using “brand” batteries with a high price tag) and it was getting too expensive so I thought I’d give these a try. For my complete astonishment it’s been almost 2 months and they are going strong, way longer than the other ones.

We use these batteries in all our wireless door locks around the home. Long lasting and a great price. I would highly recommend.
