The naming convention of batteries according to IEC nomenclature. Each letter and number represents the following:

  • ‘C’ stands for its chemical composition; i.e., lithium manganese dioxide
  • ‘R’ denotes the shape of the battery, i.e., it is round
  • The number 24 represents the diameter of the battery in mm
  • 50 represents the height or thickness of the battery in mm

CR2450 Specifications

One of the excellent characteristics of these batteries is their long shelf life. For example, consider the Panasonic lithium coin CR2450 batteries. It was found that even after 10 years of usage, they still had 90% of their initial capacity. This is why unused Panasonic Lithium Coin batteries can be kept for up to 10 years.

This is due to a combination of lithium and manganese dioxide used in the chemically stable battery. Because of their outstanding reliability and safety, Panasonic batteries have received approval under the UL safety requirements in the US and recognition worldwide.


These coin cells are preferred in applications where conventional batteries are ineffective. Due to their higher power capacity, and compact size, they can be used in products having snap-fit designs. The common electronic devices that use these coin cells are listed below:

  • Calculators
  • Toys
  • Digital watches
  • Laser pens
  • Computer motherboards
  • LED flashlights
  • Security systems
  • Wearable electronics
  • Pedometers
  • Stopwatches
  • Car keys and car remotes
  • Keyless door entry
  • PDA mem-backup
  • Cameras
  • Medical devices
  • Clinical thermometer
  • Tensiometer
  • Fitness appliances
  • Calorie counters


Is CR2032 the same as CR2450?

Though the nominal voltage of both these batteries is the same (i.e. 3V), both of them have different capacities. CR2450 has a capacity of 600-620 mAh whereas CR2032 has a capacity of 210-230 mAh. CR2450 even has a larger volume than CR2032. Hence, they are not the same.

What is the CR2450 battery’s lifespan?

The lifespan of 2450 coin cells depends on how frequently they are used. Using them continuously at standard operating conditions can last up to 1400 hours. But, if they are used occasionally or not used at all, they last up to 10 years.

What is the difference between CR2450 and CR2450N?

CR2450 has a capacity of 600 mAh, while the CR2450N has a capacity of 540 mAh. Thus, CR2450 has a slightly higher capacity than CR2450N.
