What Are CR123 and CR2 Batteries?

CR123 Batteries

CR123 batteries, also referred to as CR123A or 123 batteries, are lithium batteries that provide a nominal voltage of 3 volts. Measuring approximately 34.5 mm in length and 17 mm in diameter, these batteries are known for their high energy density and long shelf life, making them ideal for high-drain devices.

Key Features:

Voltage: 3V
Chemistry: Lithium
Capacity: Varies by brand, typically around 1500 mAh to 1700 mAh
Shelf Life: Up to 10 years

CR2 Batteries

CR2 batteries are also lithium batteries but are slightly different in size and specifications. They provide a nominal voltage of 3 volts and measure approximately 27 mm in length and 15.6 mm in diameter. CR2 batteries are commonly used in devices that require reliable power without the bulkiness of larger batteries.

Key Features:

Voltage: 3V
Chemistry: Lithium
Capacity: Generally around 800 mAh to 1000 mAh
Shelf Life: Up to 10 years
