Hello ES13Raven,
An educated guess would be 6 - 8 years.

Tom, I may be misunderstanding your post and the OP's post - these would hold a charge for 6-8 years?

Wow... so there is little to no discharge?

I might point out, that in certain lights with sophisticated electronics, such as the LiteFlux "Beacon" series (or "Beacon" serials, as they like to put it. 
), for example, there is a small drain that, over time would impact the charge state of the cell. Also, if I'm not mistaken, some protection circuits cause a small drain as well.

2 of those sit in my scorpion for about 3 months at a time without any problems, it used to be my bedside light so it doesn't get much use, just sitting there on my bedside waiting for the bump in the night.

What voltage were they when you received them?
For me, I bought 6 cells + charger and 2 of the cells were nearly dead when I received them and 1 was pretty low.
So for good cells, fully charged they may last a long time but I don't know if your Tenergy's will.
(I know they don't ship Lipos or LiFePO4 cells fully charged, but they don't ship them measuring 0.8V either! )

Tom, I'm ending up with .7V or .8V differences in my 3 new protected Tenergy 900's after 3, 8-minute runs in my EZnite. Do all of the protective circuits skew the readings? Do I need to be concerned with this. I am very gunshy running multiple 123's in lights.

Hello BVH,
Li-Ion cells are only balanced when fully charged. Once you use them, the balance falls off. Balance is most important when charging cells in series. If the cells are out of balance, you run the risk of overcharging. Secondly, you want to start with a balance charge to get the best performance from your cells.
When I use multiple cells, I first match them on capacity. Then I know that they will all pull together if they start off charged to the same voltage.

OK, that all makes sense. I can use my Triton to do some discharge capacity tests and then charge them individually and ensure the charged voltage is within the range you cited above. Is there a typical time I should let them sit after charging to take the measurement?

Hello BVH,
Li-Ion cells usually stabilize very quickly. I usually only wait 10 - 15 minutes.
