3V 600mAh CR2450 LiMnO2 (Normal/Wide temperature) Battery for Automotive TPMS sensors, Electronic toll collection (ETC) systems, Keyless entry systems

The CR2450 Li-MnO₂ battery is a widely used 3.0V lithium coin cell designed for compact electronic devices that require reliable and long-lasting power. With a typical diameter of 24mm and a thickness of 5.0mm, the CR2450 offers a higher capacity than many smaller coin cells, making it suitable for applications that demand longer operating time.

These batteries use lithium-manganese dioxide chemistry, which provides stable voltage output, low self-discharge, and excellent shelf life—often up to 8–10 years under proper storage conditions. The stable discharge characteristics ensure consistent performance in low-power electronics.

CR2450 batteries are commonly used in devices such as key fobs, smart sensors, medical instruments, security systems, calculators, and backup memory circuits. Their compact design, high energy density, and reliable performance make them a popular choice for both consumer electronics and industrial applications.

When selecting a CR2450 battery, it is important to consider factors such as capacity, discharge characteristics, and operating temperature to ensure optimal performance for specific devices.

The graph illustrates the discharge performance of a CR2450 battery under a constant discharge load of 7.5KΩ across three different temperatures. The x-axis tracks the discharging time in hours, while the y-axis measures the corresponding voltage. The plotted curves for 85°C and 20°C exhibit very similar and stable voltage retention, maintaining a high voltage for the majority of the test before dropping to the 2.0V mark between 1500 and 1600 hours. In contrast, the battery’s performance drops significantly at -40°C; the voltage declines more rapidly and hits the 2.0V threshold much earlier, at approximately 900 hours.
