BONAICR123A Batteries 3v Lithium Battery High Capacity CR123 CR17345 12PC for Flashlight and Security Device Non-Rechargeable

Got these to test in my red dot sights and three different high-intensity tactical lights.Initial tests are favorable; they install and work great in everything I've used them in so far; can't yet speak to them being any more or less log-lasting in average use conditions than others I've been using, but no issues and they seem very well-made.These batteries installed perfectly in some tactical lights where other CR123's seemed to not fit well; so points for that.The best test I could think of was to load them into my SightMark IR Mini scope and run them for a few hours straight.In about three solid hours of use in and outside, these batteries performed very well; never went into low battery mode, so I will say they are a good value... I would like to test them this Winter (have to wait a bit for that update) and see how they perform compared to the EverReady Extreme Duty batteries I use outdoors in low temps, but I'll be sure to try them and post an update.

So, I'm not really sure how to review batteries. I got these for the motion sensor in my home security system. They fit, they work, but only time will tell if how long they last. The ones I replaced were here when I moved in 2 years ago, so we will see how long these last. If they only last a short time, I will come back and edit the review. But they're batteries, and they work, so I guess that's all that can be said for now.

I have several high powered flashlights, range finders and night vision devices which will take either CR123A's or rechargeable 18650's. The CR123's have the advantage of long shelf life; in this case 10 years, which means they can stay in your gear bag or dresser drawer for a very long time and be available for immediate use. These CR123A's are claimed to have PTC protection which will shut the battery down if the current overloads by reacting to high heat. In about 30 years this has happened to me one time with a CR123A. Given that this particular battery technology has been around since 1991 and the production quality has improved across the board, IMO I'm willing to give these a try where a decade ago I'd have only trusted about 4 brands. If there's an update to this review, it will be due to some deficiency with the battery as I put it through it's paces. If no update in 3-4 months, then this will be a good buy.

If you need CR123A batteries...these are the one for you. Typically when you purchase these batteries they come in a small package. This has 12 batteries which is nice to have if you have several devices that require these batteries. They come in three packages of 4 which allows for easy transport and storage.

I recommend these Lithium Batteries for anyone in need of high-capacity, reliable power sources for their devices. The performance, compatibility, and safety factors make them a worthwhile investment. With the convenience of a 12-pack, I feel confident that I will be prepared for any power requirements that arise in my home. If you’re looking for a dependable battery solution, look no further than BONAI.

These seem like fine CR123A batteries. Weight of 17g and open circuit voltage of 3.27V are comparable to Surefire branded batteries. They work just fine in my flashlight.The date code marked on each reads last month.The lithium manganese dioxide battery chemistry won't leak, is lighter, and has a much longer shelf life than typical alkaline batteries.

Batteries came well packaged.Nothing too crazy, just a paper box, and 3 rows of shrink wrapped really well.These are going to be used on my Eufy Door Lock, which with rechargeable batteries last about 2months with regular use.I'll update the review once I get further time with it, but after 2 weeks and at least 2 openings a day, its still showing at 100% and going strong!

The thing here is that Bonai and other "off" brands are made in regular factories whereas the "marquis" brands like Duracell and Energizer are made under candlelight in specially engineered and constructed facilities run by specialists who only graduate to "Specialist Battery Maker" after a decades-long apprenticeship. This is why the marquis brands can charge as much as $6-8 per battery for specialized form factors such as the CR123A (which require an advanced post-apprenticeship training program).So now you know.If that makes sense to you, keep buying brand names. If on the other hand you recognize that these things are commodities that pretty much come from the same factories and the price difference (like in every other consumer product) is largely driven by marketing designed to engage exclusivity, well, then Bonai here is a nice very attractively-priced box of CR123A batteries that work just fine. I promise your smoke detector or SureFire tac light won't even be able to tell the difference (at least mine didn't).4 stars just because, they're BATTERIES, so there wasn't much to make them wow me.
