Proper charge cycles for CR123A?

[JBTexas]

It was relatively easy for me to find info on 18650 batteries; WHEN they should be charged, WHAT a full charge is, etc.; found the data on the web AND in the forum.
=====
18650:
Full charge = ~ 4.1 to 4.2 volts
WHEN they should be charged for best lifetime = 3.7 to 3.8 volts

(please correct me if I am wrong...)
=====
BUT... I cannot for the life of me find comparable data on CR123A's (?!??). Tried all kinds of searches...

These are: CR123A (16340), 3.7v rechargables. The capacities are 650 & 800 mAh.
I don't know FOR CERTAIN what a full charge is,
and I don't know FOR CERTAIN when I should stop and charge them.
These are used in the 200mw green Gatlin that I got from O-Like.

JB;

Full voltage after charging is 4.2 VDC.

I would discharge them down to about 3.4 VDC (after a few minutes rest).

I always like more Texans on the LPF board.

LarryDFW; THANKS! You wouldn't BELIEVE how much seaching I've done to try to find a good answer for this.
