Streamlight 85177 CR123A Lithium Batteries, 12-Pack

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.

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.

Easy to install, they last a LONG time, tiny in size...but they need to be small enough for the alarm sensors, obviously made this size for this very reason. They work for YEARS before the panel starts chirping, and I have to do a zone check to find out which one it is. Heat level?? They don't burn the inside of the sensors at all, so I would say the heat level is minimal, as they also have great insulation in the packaging.

Working well. No issues.

These are fine. They’re affordable and last okay. Other brands might last longer but they’re a lot more money too.

Batteries, work find in my flashlights - both separate and attached as accessories to something else. Reliable, functional - just do not forget to change them once in a while.

Still using them. Last a long time. Good price for pack!

You get what you pay for!Don't waste time saving a few dollars. The main reason we need these types of batteries is mostly for emergency situations and running equipment that we need in a bad situation such as weapon optics and lights. Is that something to risk cheeping out on?I served in the infantry for 11 years and now provide tactical classes on the side. In the service and out I will never depend on another battery.I go through a lot of these batteries so of course have explored "cheaper" options. Take it from me, don't waste your time. Every battery I have tried has been unpredictable with its longevity.These Streamlight batteries are the best of the best when it comes to longevity and dependability, and I have bet my life on them on several occasions.
