I bought them for my Arlo Cameras and they lasted less than a week. 3 of my camera's are not overly active and maybe record 6-8 times a day. The busiest camera is the front door, and the batteries stopped working after 2 days. That's with maybe 12-15 recordings, 15 seconds a piece and the setting at best battery quality. Do not buy if you plan to use with Arlo Cameras, they're a waste of money.

Purchased a 12 pack because of the good price for my Netgear Arlo Video camera. After 6 days my Arlo says the batteries are at 20%. This camera is in the rear of my house and has very little foot traffic. It has only recorded 3 videos since I started using them. At the very least I'd expect them to last a month, but less then 10 days? Horrible.

I bought the 20 pack, received beginning of August and quickly realized I had to switch back to my normal brand (Streamlight). I went through 20 batteries in 30 days. For those of you who have Arlo with the batteries, you know the frustration, but I never replace my batteries weekly. The cameras I replaced usually last one month.
These batteries are probably better for flashlights as other posts have mentioned. Nothing abnormal happened with activity or weather. They all read at 90% when I first put them in but they seemed to drain much faster. I am not a battery expert, just my opinion that for arlo plus a driveway, I don't like this brand. Hope this helps someone else. I bought it originally for the price and quantity, but didn't help in the long run.

Wish I could give zero stars. I reached out to the seller months ago and have received no response.

These batteries arrived dead. I use these for my ARLO system and usually can get months of use. These didn’t make it past one recording. In fact, the battery indicator showed the charge was low the second I put them in the cameras.

Out of all my purchases this has been the worst of my experiences.

I don’t like to give bad reviews. I always give the seller the opportunity to fix the issue.

Very unfortunate.

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.

UPDATES: Interestingly within 8 months these batteries lost the power while inside it's original box. When i tried using them on my arlo cameras, the brand new batteries were showing having only 30% JUICE LEFT. Dishonest product manufacturer...

I have some security cameras for which i used Duracell batteries. Duracell batteries are little expensive but they run for 5-6 months on my wireless security cameras. I decided to purchase this brand since they were inexpensive. I thought it was due to bulk quality that seller can afford a lower price. But I was wrong. the quality of this product is really poor. I used it in all my security cameras and they drained completely within 2 months. There had been no change in the settings whatsoever. I think I will just use all the batteries over next few months and switch back to Duracell.

Lesson Learnt, you get what you paid for. Cheap product cheap quality.

You're probably already aware that CR123 batteries can be pretty pricey; if you use them in high drain applications (ie high output flashlights), you can really burn through some money keeping them powered!

I use them in a 700 lumen Sig Sauer Stoplite, and I can go through 8 or 12 of these in a single night if it stays on most of the time, so the low price is pretty important to me. I doubt you'll find them cheaper anywhere else, and if you go through as many of these bad boys as I do, that's worth something!

On the other hand, I've noted (as have a few other reviewers) that output isn't equal to that of top of the line CR123s I've used, but the lumen output on my Stoplite is still sufficient to light up a stand of trees better than 100 yards away or blind an assailant if necessary (or yourself if you don't watch where you point that thing, watch out for mirrors lol).

They don't last as long as top of the line batteries either, but even so, I save a nice pile of coin by using these instead of paying 5 - 10 times more for name brands. They may last a little longer, maybe even twice as long, but nowhere near 5 - 10 times as long.

If cost efficiency is important to you, I'd recommend these without any reservation. There is a moderately noticeable difference in quality between them and name brands, but not enough to make them a bad product, and in my opinion it is more than compensated for by the savings.

I hope some of you find my review helpful in making a more informed purchasing decision. Peace :-)

Delivered and installed in netgear's Arlo system on December 31st. Died today, January 11th, 2016. These replaced the original batteries which last me over 7 months. Yes 7 months. I do not keep it on. It is motion detection. I probably used it 5 times. Zero footage was captured. When I say use it, I arm the system to detect motion. No motion was detected. Just dead batteries.

DO NOT BUY! Tried two sets of four of these batteries in my Arlo cameras and they would not function at all. Batteries didn’t have enough juice to even get a few minutes use out of them. These are a rip off and not sure how or why Amazon allows them to be sold. Buy at your own risk. Waited too long now to be allowed to return them. Wow, wasted $40.

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.
