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

Batteries are great and I use it for a flash light. The batteries last me about 6 months before needing to be replaced. The size is accurate to the battery sizing and perform well. Good buy and the batteries work just as good as other brands.

Great product and fast delivery. Price is right.

Great quality and long lasting!

They work great. Not as long as I would like, but they are just fine.

Battery work as expected

Product as described. Packeaged with another order and I missed it in the box and gave a bad review (In Error) My fault for not unwrapping all the packaging material.

As advertised

If you’re purchasing batteries for smoke or carbon monoxide detectors, I strongly recommend sticking with a trusted brand. My first experience with these batteries was disappointing, they only lasted about two months, when I expected at least six months of reliable performance. Hoping it was a one-time issue, I gave them another try, but the second set didn’t even last 24 hours. In terms of compatibility, they did fit and function initially, but the battery capacity and overall performance were extremely poor. There were no leakage issues that I noticed, but the short lifespan raises serious concerns about reliability, especially for safety devices. On the positive side, the packaging and overall appearance were appealing, and the replacement process was straightforward. However, none of that makes up for the lack of durability and consistency. Overall, this product does not offer good value for the money. I would not recommend using these batteries for essential devices where dependable performance is critical.

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.

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.

All good for our security cameras

Works well in my August door lock.

Great project!
