Great

Awesome replacement battery's I have had mine since July 2018 & they work well in my Arlo Cameras as long as you do not leave on live mode all the time. Why would you. You only need them if someone walks by or there's Motion. They say these are not good but they work great on all my outdoor Arlo Cameras. The rest just wants you to spend more for re-chargeables. I got news. I bought the re-install rechargeable tenergy for Arlo and they burned out my charger and my cameras. So these were alternative which work just fine. So stop hating.

good batteries

The Tenergy batteries are pretty good batteries. I have purchased them several times in the past. They usually last about a month in my surveillance cameras. It usually depends on how much motion us detected. I have always been pretty satisfied with this brand. I am really glad that they come in a set of 12 because my cameras take 4 each x3 cameras. Although I really wish they would last longer, but that also has to do with my settings. Good batteries,keep up the good work Tenergy.

Tenergy 3V CR123A Lithium Batteries PTC Protected

I bought this 12 pack Tenergy 3V CR123A Lithium Batteries for my Nikon camera and flash lights. These fit pretty well in my gadgets physically and they're easy to insert/remove. I have been using them for a few days and so far I don't need to replace the battery yet so so far so good. There is a clear label on the package indicates these are not "rechargeable" and is only for one-time use. I like that these batteries are listed to be PTC protected, which would provides over-current circuit protection. Basically the way PTC works is that it will change from a low resistance to a high resistance to limit current flow when temperature is high and will reset once the battery cools down.

No issues with Arlo Camera

I have been using this for the Arlo outdoor camera for few years now. The description states that these are not meant for Arlo. The ones stated for Arlo were more costly, so I never ventured into them. Batteries run for several months depending on the video capture. I'm getting similar battery life as the original batteries that Arlo came with. I will still continue to use these until I start seeing some issues. So far so good.

The low price of these seemed a little too good to be true

I bought a twelve-pack of these, and also a 12-pack of Streamligh 85177 CR132s for comparison. The low price of these seemed a little too good to be true. I immediately got out the DMM to compare voltages. The Tenergy batteries consistently tested at a higher voltage--the Streamlights were between 3.21-3.23, while the Tenergys tested between 3.25-3.28, with the average around 3.26. I use these in a very high-draw, 1100 lumen LED flashlight, and after a few nights of fooling around, I'm still running the first set of three with no noticeable dimming.

Good batteries...

Bought these for my Arlo security cameras. The box arrived with 40 brand new perfect batteries & in my tester they registered 100%, but installed in the Arlo they register at 75%. Not as good as the Duracell Ultra that the Arlos came with, but they work for now and work fine with my other cameras and other items requiring CR123A batteries, thus the 5 star rating. FYI...they aren't draining particularly fast in the Arlo cameras, so they do actually work and deserve to keep the 5 star rating. UPDATE: After using for 3 months, using these in half my cameras and the Duracell in half. It seems that for the price difference, these are the better deal. I have ordered another batch of Tenergy batteries for my Arlo cameras. They last almost as long as the Duracell for a much better price. The Texas heat is the biggest drain, as the outside cameras drain faster than the inside and don't register that the batteries are even going down that fast, the cameras will just suddenly go offline. Can't really blame the batteries or the cameras, I go offline after a few minutes of being outside in temperatures over 100 degrees Fahrenheit.

Power Puncher and Effective

We go through a dozen of these almost every month due to our going outside with the dogs at night and using our flashlight as more of a pest deterrent rather than a light. Last night was a good example. We were out with them in the back and heard a noise in the woods. We shined the light in the direction of the noise and we received a signal of 6 bright eyes looking back: one large set of eyes and 2 sets of smaller eyes. It was probably a mom and her fawns or a bear and 2 cubs. Regardless, the next thing was a sound of escape on their part. The Defender flashlight uses CR123A batteries faster than any of the other flashlights in the house but it is the only one that can put out a real light and it could not do that if it were not for Tenergy's Lithium batteries. I have not yet finished my quality and use study on these batteries compared to other brands but the preliminary results suggest these Tenergy batteries are better than the others and cheaper per unit. Additionally, I use CR123A Lithium batteries in two other lights and they have lasted significantly longer than other brands but my cheapness is going to show in a second. Instead of disposing of the used Defender batteries I keep them to use in the two flashlights which only require 2 batteries each instead of 4. While the output is modestly reduced the quality of the light is sufficient to permit satisfactory light when and where I need it and I save a few pennies a month with less hassle.

Best value, just as good as name brands.

My first encounter with CR123s was their requirement in a Surefire flashlight that was issued to me by the US Marine Corps some 6 years ago. We had boxes of the Surefire brand CR123, and generics like these laying around every where. I bought these for a Streamlight I own after getting sick to my stomach paying $16.00 every time the light died, as my endless supply of free CR123s from the military had ended as I left the service. These are just as good as any name brand store bought CR123's, and at $1.00 a battery (as opposed to $8.00 per), much more friendly on the wallet. I've gone only through about a strip and a half and its been over a year now since I purchased these and I use my flash light extensively at work each night. I'd say I only have to change the batteries once every two months at most, so these are just as good (if not better) as the Duracell or Energizer rip-offs you find in the stores, or the somewhat over priced Surefire brand CR123s. 5/14/2014 - I actually just ordered a pack of these for my brother and thought I would give an update. I still have had no issues with these batteries and actually still have 14 batteries left out of my original order some years ago. I still work overnights and use the flash light a good bit, even around the house. Battery life is just as good still as any 'name brand' that costs twice as much, so this in my humble opinion, is still one of your best bang-for-buck options if you need CR123s on the cheap.

Excellent value for under a buck each.

This will be my 5th order of this product in eight years. The batteries are used in LED flashlights, two single cell lights and one triple cell. They last a fair time, we probably change batteries in one or another flashlight about monthly. (The triple cell gets used most nights, the single cells are bedside lights). Every time I order, I check alternatives. How unsuccessfully I am at that is arrested by this fifth order. Cannot find anything else that gives the run time per dollar these do.

Arlo camera, so far so good.

So far so good. This product was much cheaper than the rest. this is probably my 3rd of 4th time buying tenergy products. Use to mostly buy the rechargeable NiMH batteries. I've placed them into the Arlo cameras and so far, all are working after 1-2 months. Please click helpful if this helped you.
