Streamlight 85177 3V Batteries, 12-Pack

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.

nice but too expensive

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

Bought this a while ago! Here’s the deal package came opened, like all over the box were batteries.But battery life is long, maybe switched out twice since I purchased and I’m quite impressed. Reason for the 4 is disappointed in quality of packaging.

Long-Lasting Power You Can Count OnThese 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.

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

As I age my eyes do not see in the dark as well as they once did. I carry a small flashlight in my EDC pack. I have to work nights and need the flashlight often. I would be stuck if the battery died in the middle of a job. I use this light because of its size and the beam it produces. Unfortunately, the batteries seem to, die suddenly. The CR 123 battery is perfect to carry and have it ready to switch out when needed.This pack has quality batteries at a fair price.

The Streamlight CR123As provide reliable, consistent output that's essential for weapon-mounted lights. They maintain steady voltage throughout their life cycle, ensuring your light performs at full brightness when needed. The build quality is excellent, with robust casings that can handle recoil without connection issues.I've tested these extensively and they outperform generic brands significantly in terms of both longevity and consistent power delivery. The individual packaging helps prevent accidental discharge during storage, and their impressive shelf life makes them perfect for backup supplies.The temperature tolerance is noteworthy - they maintain performance in both cold and hot conditions that can cause other batteries to falter. While they cost more than generic options, the reliability in critical situations justifies the premium. I've never experienced premature failure or voltage inconsistencies that could compromise functionality.For weapon lights where dependability is paramount, these Streamlight batteries are a sound investment. They provide predictable performance without the voltage drops or compatibility issues sometimes found with cheaper alternatives. Having tested various brands, these remain my go-to choice for any application requiring absolute reliability.​​​​​​​​​​​​​​​​

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）

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.

We used these to replace some dying Duracell batteries in our Honeywell alarm system. We've had zero issues so far with the batteries dying quickly (though they are still early-on in the life they *should* have). At this point, I see no reason not to recommend them! Great price for a battery which can easily cost multiples more from other retailers or brands.

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