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

I am switching over all my battery powered flashlights to ones that use these CR123A batteries. The shelf life on these is ten years, and more importantly, I have never seen one of these leak. The standard alkaline batteries seem to leak all the time nowadays. It didn't used to be that way. These batteries are high quality. They fit and function just like the brand name versions. Quality and capacity are good. They are a good value.

Came in on time, had full charge, and fit the smoke detectors. As we just installed them we have no way of knowing how long they will last vs. the originals that came with the detectors. But these were fully charged, and the detectors stopped chirping after putting these in, so 5 Stars for our peace of mind.Also, the price was good compared to purchasing these locally, plus we didn't have to drive around looking for them.

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.

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

Long lasting batteries with good shelf life. Something you could have in your house all year long for use when needed.

Works really well for my arlo camera last about 2-3 months that’s because I have camera on high setting which drain battery faster

Good price. Fits flashlight as well as some parts of security systems.

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.

Works well in my August door lock.

They seem ok so far see how long they last

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