BR1225 vs CR1225 Batteries
BR1225 vs CR1225 Battery
The BR1225 and CR1225 are both 3V lithium coin cells with a diameter of 12.5 mm and a height of 2.5 mm. They have similar capacities, with the BR1225 having a typical capacity of 48mAh and the CR1225 around 50mAh. Both types can be used on small electronic devices such as watches, calculators, keychains, etc. Here are the main differences between BR1225 and CR1225 batteries:
BR1225 vs CR1225: Chemistry
The CR1225 battery is based on lithium manganese dioxide chemistry. It offers a good balance of high energy density and stable voltage, making it suitable for a wide range of applications.
The BR1225 battery uses lithium carbon monofluoride chemistry. It is generally more stable under a range of temperature conditions and has a slightly higher self-discharge rate, making it less ideal for long-term applications compared to CR1225.
BR1225 vs CR1225: Temperature Resistance
BR1225 battery is more suitable for high temperature environments. Its chemical properties allow it to operate effectively over a wider temperature range, typically -30°C to +85°C. CR1225 batteries, while also capable of operating in a wide range of temperatures, may not perform as well as BR1225 in extreme conditions.
BR1225 vs CR1225: Applications
CR1225 batteries are commonly used in watches, calculators and other portable devices that require stable power supply over a long period of time.
BR1225 batteries are often chosen for applications that require battery operation in higher temperature environments, such as car key fobs and medical equipment.
BR1225 vs CR1225: Interchangeability
While both batteries can be interchangeable in terms of size and voltage, the choice between them should consider the device's temperature requirements and expected battery life. The BR1225's superior temperature resistance might be more appropriate for certain uses, whereas the CR1225's generally longer life and stable output make it suitable for everyday electronic devices.
