Complete Guide to CR2450 Li-MnO2 Batteries
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.
Discharge Characteristics by Load Test Condition - Constant discharge
The graph illustrates the performance of a CR2450 battery under three different constant discharge loads—3KΩ, 7.5KΩ, and 15KΩ—while maintained at a constant temperature of 20°C. The horizontal x-axis tracks the discharging time in hours, and the vertical y-axis measures the corresponding voltage.3KΩ Load: Under this heavier load, the battery discharges most rapidly, with the voltage dropping to the 2.0V cutoff point just before the 600-hour mark.
7.5KΩ Load: With a moderate load, the battery’s lifespan is significantly extended, maintaining its voltage until it reaches the 2.0V threshold slightly past 1500 hours.
15KΩ Load: Under the lightest load tested, the battery sustains a usable voltage for the longest duration, lasting well over 3000 hours before declining to 2.0V.
Discharge Characteristics by Temperature Test Condition - Constant discharge
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.
CR2450 Material Description and MSDS
The CR2450 battery’s anode is composed of manganese dioxide powder and colloid graphite powder. Its cathode consists of a lithium slice. The internal electrolyte is a chemical mixture containing ethylene glycol dimethyl ether, propylene carbonate, and lithium perchloride. These internal components are housed within a protective “rind” made of a stainless steel shell. Additionally, the battery includes other materials such as a fiberglass septum and acetylene black.
