How far to run CR123's voltage wise

[nickz]

I want to prevent any danger of venting one of these batteries in a light. I have a G2L that I have been running a set of SF123's for quite some time. It still puts out useable light but is way dimmer than a new set. The voltage of the first cell is 2.02v while the second cell is 2.05v.

Am I pushing things too far by continuing to run these cells?

Since these are SureFire batteries, run them till they are dead.

provided that the cells are good quality and have very similar initial capacities, you can pretty much run them till they are dead as doornails. It's when you have cells that are mismatched that problems arise. Cheaper brands commonly have cells in the mix that are not "full" so to speak. SF brand cells should be safe to run into the ground.

Sounds great. Thanks guys ;-)
