Streamlight 85177 CR123A Lithium Batteries, 12-Pack

I recently bought the Streamlight 85177 CR123A Lithium Batteries, 12-Pack, and I am extremely impressed with their performance. These batteries are top-notch and provide long-lasting power for all my devices that require CR123A batteries, especially my flashlights. I’ve used them in both high-end tactical flashlights and everyday-use LED lights, and they’ve consistently delivered excellent results.One of the standout features of these batteries is their longevity. They last much longer than other standard batteries I’ve used, and even with heavy usage, they don’t lose their charge quickly. I can rely on them for extended periods of time without worrying about running out of power during important tasks or emergencies. The 12-pack is a great deal, especially considering the quality and reliability of the Streamlight brand.

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.​​​​​​​​​​​​​​​​

THESE BATTERIES WORK - BUT THEY DON'T LAST VERY LONG! We have found they last only 1.5 hours of sustained use. But fresh batteries really provide a strong beam of light in the new flashlight. If they were rechargeable we'd love them even more. We will re-order and will hope the manufacturer will improve them.

These Streamlight 85177 CR123A batteries are fantastic! Consistent performance, great shelf life, and perfect for flashlights or optics. The 12-pack offers excellent value. Highly recommend for durability and reliability. A must-have!

Here's another one of those split reviews. These batteries have worked fine for me in the past. That's why I buy them, but...Shaved a star because this time I got a pack with 2 dead cells in it. Both showed 2.88vdc and would not work in combination with any of the good batteries in a Surefire 2 cell light. Should have been 3vdc or better. Both stamped "02 2032". The other 10 in the pack were G2G.The return mechanism doesn't allow for returning individual items out of a multi-item package. So, this is the only way of letting Amazon know. Didn't want to mess around with returning the 10 good lithium batts because 2 were bad.Hey Amazon, if you like, feel free to send me 2 good replacement CR123A lithium batts...I'd appreciate it. I'll dispose of the 2 bad ones properly. Also, let Streamlight know a customer got a couple of duds.

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.

Works well, better price than local stores, would buy again
