Compare CR2 and 2CR5 batteries: sizes, typical uses, and which camera gear needs them. Make the right choice for your photo equipment.
Quick answer
Choose 2CR5 batteries for devices designed for that larger, rectangular battery, and CR2 batteries for slimmer gear that takes two separate cells. Check your device's manual before ordering to avoid compatibility issues.
Size and shape differences
The 2CR5 is a single, rectangular battery that combines two 3V cells in one pack. It's often used in older film SLR cameras and some flash units. The CR2 is a smaller, cylindrical cell, and many devices take two of them side by side. Because of the different form factors, you cannot swap one for the other without an adapter.
Why device compatibility matters
Battery type is determined by the device's battery compartment, not by voltage alone. Both CR2 and 2CR5 provide 6V total, but the physical shape and terminal layout differ. Always check the battery type indicated on your device or in its manual before purchasing.
Trade-offs at a glance
- 2CR5 battery: Single rectangular battery, often used in larger cameras and flashes. Easier to install correctly, but bulkier to store. Check that your device lists 2CR5 as the required type.
- CR2 battery (pack of two): Two cylindrical cells, used in slimmer devices. More flexible if you only need one cell, but you must insert both correctly. Verify that your device takes two CR2 batteries before buying a pack.
- Compatibility check: Never assume interchangeability based on voltage. Confirm the exact battery type in your device's manual or on the battery compartment label. When in doubt, consult the manufacturer's specifications.
