5.0 out of 5 stars CR-123 for $1 ea. Amazing some people paid $8 ea. March 23, 2010

UPDATE -how good are these in actual use?

Just as good as the $8 cell!

I had to change out an alarm system that used 8 CR123 cells and was calling home to complain about its batteries being low. So I've used 1/4 box so far. Factory new they measure 3.23V and I've also run a set in a surefire E2D with equal runtime to the factory cellls. Have no fear - cheap CR123's are here!

(review)

The cr-123 cell is an amazing primary (disposable) battery. It's high energy capacy, 3.0 v output, and compact size combined with 10 year shelf life have led to its design into alarms, flashlights, weapons systems, night vision, basically anything that needs dependable power for a long time or at a high rate.

The box comes with 4 strips of 10 cells shrink-wrapped for protection. They measure 3.23V open circuit out of the box indicating they are fresh manufacture (the ademco alarm components signal a low-battery indication at 2.8V so there is a narrow band of usefulness) I tested 2 of these in my surefire e2d on high and low without any problems.

Tenergy makes 2 versions of the CR-123 - the 1300 mAh and the 1400 mAh, this is the 1400 mAh spec on their website.

When the CR-123 cell first came out it was a photographic cell and sold at drugstores for as much as $8 ea. Even the best pricing on Duracells CR-123 is 1.89 in large quantity. To get 40 batteries for under 40 dollars is a great feat. All of my ademco wireless sensors use the CR-123 and need to be changed about every 6 years, which is now so this was a great find at the right time.

While some people will swear by a brand (e.g. I always use surefire/duracell/xyz brand), I'm finding that the CR123 is much like gasoline - yes there are subtle differences between arco and shell but both will run you car down the road. Do I want to spend another $36 dollars to get a different wrapper to replace all of my alarm sensors and load up my flashlight. Not now. If for some reason these go dead ahead of time I will update my review, but just getting them I can find no reason not to give them 5 stars as compared to other 5 star 1400 mAh cells on the market. Stay tuned - it may take a while to find out how long they really last due to their long shelf life of 10 years.

5.0 out of 5 stars Just as good as any other CR123A battery April 9, 2010

My flashlight really sucks down batteries, so I figured I'd give these a shot. I was tired of paying $8 to change my batteries. I'm glad I tried these. They last just as long, don't overheat, and fit perfectly. They are probably the same battery, just with a different label. Get them, they are great.

5.0 out of 5 stars These Appear to be Excellent! May 20, 2010

Just purchased my first batch of these from Amazon & decided to test/install one on my Novatac 120P LED flashlight...Run time for the battery exceeded Novatac's specs, so I am very satisfied with these! I also tested the initial voltage...they register 3.1v out-of-the-box. By comparison, I also purchased a 12-pack of the Streamlight CR123A batteries from Amazon also...those registered slightly higher (3.2v), but I doubt overall performance is materially different. I cannot confirm the mAh for either of the brands (neither the battery or packaging was marked with that info), but my test Tenergy battery performed flawlessly, so I will exclusively source these from here on out. At $1 each, you can't beat the value (in my opinion); conversely, both the Streamlight (& SureFire) 12-packs now range from $21-28 (~$2 each)--about double the cost. My only disappointment was not having a manufacture date clearly marked on these batteries (or the box itself); they come shrink-wrapped in 4 10-packs inside the box, but no markings there either :( The only thing was a 2009 Copyright date on the box itself...I assume they were produced at some point in 2009; regardless, I rotate all my batteries/supplies using a First-In-First-Out methodology. Even if they were '08 production, you still can't beat the price. FYI: the Streamlight pack I bought had an 0810 stamp (since it's only May, I'll assume that meant they were made in Aug-08). A 2-pack of Duracell's I had showed an Oct-09 date, so it appears the global supply chain doesn't move/turnover CR123A inventory too fast...could be quite a few things behind that, but (obviously) with the long shelf-life it isn't a huge concern. I may ultimately buy one pack of the SureFire batteries also, just to see their manufacture date & try them out, but I can't provide any feedback on them at the moment...
