Low Current
The Idea is great, i used these batteries on the V2 lithium flash light , and they worked fine, but when i bought the Fenix P1D Cree edition , they couldn't produced enough juice to produce 135 lumen on the flash light, conventional A123 (non rechargeable )can give you that due to there hight current output.

UltraLast Rechargable Battery Pack
Not bad! The charger prongs needed to be bent to ensure they charge properly. Other than that they're great!

Avoid
I bought this a few months ago and they worked fine in the supplied Ultralast Charger for three times.
After that. One battery died (voltage always 0.02) and the other stuck around 2.5V. I verified the charger was working, but the batteries were defective.
Be warned that the company NAB refuses to even discuss this with me (it's only $10... jeez).
Buy real lithium 123's for $1 instead of this garbage.
DISAPPOINTED!

A good idea ...
I've been shooting more photos with my digital camera, but I wasn't ready to give up my film camera for good -- I just didn't want to keep spending $6.00 for a battery every few months. I've only just started seeing rechargable cr123's and I liked the idea of getting 2 rechargables and the charger for about what 3 standard batteries cost.
On my first try one of the batteries wouldn't charge properly, so I had to return it for replacement (a nearly painless procedure, thanks Amazon). The second batch works well.
The process is a little trickier than the description leads you to believe. When you put two drained batteries in the charger the LED glows red, but it doesn't suddenly change to green when the batteries are fully charged. Instead, the LED gradually and smoothly shifts to orange, yellow, yellow-green and then green. Also, when it does get to green the batteries still aren't fully charged -- the best bet might be to just let it charge overnight.
I haven't tried to document how well a fully charged battery performs (700 mah) vs. a conventional lithium cr123a (typically 1400 mah). Also, I have not yet tried to measure the "shelf life" of a full charge -- but, since a conventional lithium battery has a shelf life of up to 10 years (!) I plan to carry one last conventional battery with me just in case both rechargables die when I need them, then replace it again when they're recharged.
So far, it looks good.
