In my opinion [Posted on 2007-06-05]
When I bought these batteries I understood that they had an output voltage of 3v. After charging all four I tested them with a volt meter and found they are at 3.6-3.9v. I thought the idea was a regulated output of 3.0-3.2v. Not satisfied with this product.

I bought some of these to try with a light using 123 A's. They work as advertised. When you check them with a meter they show over 3 volts, but under load they do not hurt the light. Have been using them for a while now. Hold a charge VERY well, and no longer have to buy throw away 123A's.
RECHARGEABLE CR123A BATTERIES AND"SMART" CHARGING UNIT [Posted on 2008-08-18]
BATTERIES RUN OUT OF JUICE; YOU WON'T HAVE TO WORRY ABOUT
THAT IF YOU HAVE ONE OR TWO OF THESE AROUND. IF THINGS GO "SOUTH" FOR US ALL, THIS CAN BE PLUGGED INTO A HAND CRANK SURVIVAL RADIO AND RECHARGED. GOOD IDEA.
THE CHARGER HAS "SMART" SENSORS AND DEVICES BUILT IN;
HEAT, LEAKAGE, AND BATTERY MEMORY ARE NOT A PROBLEM.
THIS IS HIGH QUALITY EQUIPTMENT. NICE PRODUCT.

Buying for a flashlight? [Posted on 2008-10-21]
These batteries appear to be great at first. They work just according to instruction, rechargeble batteries that you can be used over and over. It will save you a lot of money. So far all good.
The problem was I never got close to the runtime that I was suppose to when I used them for my FenixP3D CE Premium Q5. Estimated runtime according to the manual is 4h50min for the 120-lumens mode. With the Tenergy (900mAh) batteries I get about 1h 45 min, which is actually the best of all the 3.0V rechargeble batteries I have tested. Tenergy 750mAh gives 1h30 min, while a non rechargeble battery provide more than 5 hours of lighting!
If you are buying for a flashlight and it has a regulated voltage circuit, like my Fenix, you can buy 3.7 volt 1300mAh rechargeble batteries on for example ebay and get much longer runtime. The ones I have tested gave me 2h 30 min runtime, which is half the strength of a non-rechargeble battery, which I think is accepteble.
