Re: Rechargeable CR123 Batteries
The rechargeable version is called the RCR123. They work fine, but only have about 2/3s the capacity (don't last as long as a normal CR123)
I run the AW brand, which are one of the higher quality versions, and it also has a protective auto-shutdown circuit which prevents the battery from being excessively discharged. This is a very bad thing to do to a rechargeable Li-Ion battery. Whatever brand you buy, I'd recommend getting one with this protective circuit.
Lighthound.com is where I shop for these batteries.
