CR 123 Lithium cells are not rechargable batteries. There are several different chemistry Lithium cells on the market now. Some of the rechargables need real care to avoid severe problems when charging - hence, almost all Li cell chargers use some form of processor control and/or there are some electronics actually built into some cells.

CR 123 cells are suitable for long term storage (10 years or more). But all rechargables self-discharge over time - much faster than CR 123 or L 92 cells.

HTH clear up the confusion.
