Streamlight 85177 3V Batteries, 12-Pack | Long-life replacement power cells; Official Streamlight quality; reliable, ready-to-use power

Light worked but by the time I wrote it these batteries are dead

Do what they are susposed to. Real product. Very happy.

I used to buy my batteries from Costco, Walmart or Batteries Plus. This model of battery cost me between $2.50 and $3.50 each, depending where I could find them. They weren't always available where I usually shop. I decided to check Amazon for these batteries since Amazon had almost everything else and, low and behold, here they were. Not only were they available, but I could buy a dozen batteries for less than $1.60 each. I couldn't even find these batteries at Costco on my last visit (sometimes they have them, sometimes they don't) Batteries Plus sells this exact same battery, 12 ea., for $26.99 and Walmart sell these same batteries for $33.83. Amazon sell these for $18.66 and, if you're an Amazon Prime member, shipping is FREE! I use these batteries to power two different handgun laser sites and five different flashlights which are mounted to five different weapons, from pistols, to rigles and shotguns.This is just some of the equipment that I and my fellow officers use during our duty day. If the batteries that power our various pieces of electronic equipment are unreliable it could someone to be injured or killed. That being said, I have the upmost confidence in these batteries. These batteries work fine and have lasted a bit longer than the "popular, name brand" batteries. Because of the lower price of these batteries, when compared to what other stores offer, I can order a bunch and keep enough extras on-hand at work to not only replace my batteries as necessary, but to also provide batteries for my fellow officers in the event that their batteries wear out. Bottom line, these batteries work as well and a bit better than the "name brand" batteries, they cost a lot less and they seem to "always" be available through Amazon, unlike the other stores where I've bought these batteries where it's hit or miss that they'll be in stock. My life and the lives of my fellow officers and civilians depend on these batteries working properly to power our equipment. I would not recommend these batteries to anyone if I didn't rely on these batteries myself. Considering the dependability, superior value, equivelent battery life and ready availability, I'll be buying these and other batteries from Amazon from now on. An additional bonus is that I won't have to drive into town for batteries anymore, saving me a bunch of money in gas. So.....if anyone can find a better battery at a better price let me know. I have a feeling that I won't be hearing from anyone any time soon.

So these batteries are pretty good. They hold a long shelf life, but I will say I've had some issues with some of the batteries, losing their juice and freshness and brightness a lot sooner than they should. They're very expensive. I feel like they could be cheaper.

nice but too expensive

Long-Lasting Power You Can Count On These Streamlight CR123A lithium batteries are excellent performers. I’ve been using them in high-drain flashlights, and they hold up very well—much longer than the cheaper alternatives I’ve tried. They arrive fresh, individually packaged, and ready to go, which is nice for storage and easy to keep in a bag or drawer without worrying about contacts touching. What I especially like is their reliability. When you put them in, the flashlight works at full brightness right away—no dim or inconsistent performance. They also have a long shelf life, so even if you don’t use them right away, you know they’ll still be good years down the line. Something to keep in mind: these are not rechargeable. For me, that’s a plus since it keeps them simple and dependable, but if you’re looking for a rechargeable option, you’ll need to choose a different type. Bottom line: Great value and peace of mind for flashlights, cameras, and other gear where dependable power really matters.

Muy bueno

Been using these in my flashlights for decades with great results. Prefer Streamlight cells for the made in USA (from foreign and domestic materials) label.

The price for 6 was what the big box stores wanted for 2. They last me for a long time.

Buen precio y calidad de las materias

家で使用しているストリームライトはリチウムイオン充電池なのですが、万が一のことを考えてCA123乾電池も準備しています。災害時の対応も考えておかないといけませんからね、自然放電も少なくて、いざ使う時に威力を発揮してくれるようです。（まだ使用していませんが）

Excelentes baterías, la caducidad es de 10 años, muy satisfecho

We purchased a Streamlight helmet light for our firefighter son (he loves it!) and extra batteries seemed like a good idea. Lithium batteries are essential in cold winter conditions and our son says that knowing that his light will not fail is a huge confidence booster when he's heading into a 'fully engaged' building fire, a night time vehicle rollover, etc. That's enough of a recommendation for me.
