Cylinders and packs

CR2 and CR123A are cylindrical 3 V formats. 2CR5 and CR-P2 are 6 V packs with different outlines and contacts.

Check the complete designation

A missing character can change the package. Record the old cell, compartment diagram and camera manual together.

Avoid improvised stacks

Do not substitute loose cells or spacers for a molded camera pack unless the equipment maker provides an approved adapter.

Decision boundary

This guide narrows a battery decision but does not override the device manufacturer’s current manual or safety instructions.
