Battery Details.

The Lithium Thyonyl Chloride 2/3A can replace the CR123 in low current situations but should NEVER be used for cameras.
The CR123 can replace 2/3A Lithium Thyonyl Chloride (LiSocl2), where the extra .6 of a volt is non critical, the CR123 lasting longer.

About the Chemistry:

NOTE: These Lithium types are NOT rechargeable, they are single use batteries.
