Compared to other lithium button cells, CR2450 batteries have higher nominal voltage and energy density.
Both CR2450 and CR2032 are battery specifications that belong to the CR series of non-rechargeable button cells. Due to their similarities, they are often compared. However, can they be used as equivalents? The answer is no. Due to their different sizes and capacities, they cannot replace each other. This article will explain in detail the differences between CR2450 and CR2032, as well as the alternative models of CR2450.

Panasonic CR2450 Lithium 3V Battery
Panasonic CR2450 lithium 3v battery is sometimes called CR-2450EL. It can be used at temperatures between -22°F (-30°C) and 140°F (+60°C). The self-discharge rate is very low and the shelf-life is long. Its shelf-life is more than 10 years. Although its capacity is 620mAh, it depends on the cutoff voltage of your powered device. The constant standard drain of the Panasonic CR2450 battery is 0.42 mA.

Can CR2032 replace CR2450?
Due to the different sizes of CR2032 and CR2450, they cannot usually be directly interchangeable. CR2032 has a diameter of 20 mm and a thickness of 3.2 mm, while CR2450 has a diameter of 24 mm and a thickness of 5.0 mm. This means that the CR2032 is smaller in diameter than the CR2450 and thinner.
Therefore, if a device is designed to require a larger battery like the CR2450, the CR2032 will often not physically fit into the device's battery holder. Even if the voltage is the same, the CR2032 may not provide the same amount of use time as the CR2450 due to the difference in capacity.
Can the CR2430 replace the CR2450?
No, the CR2430 and CR2450 are the same diameter (both are 24 mm), but they are different in thickness. The CR2430 is 3.0 mm thick, while the CR2450 is 5.0 mm thick. Although they have similar chemistry and voltage, they are generally not directly interchangeable due to the difference in thickness.
where to buy cr2450 battery
You can purchase CR2450 batteries from various sources, both online and in physical stores. Here are some common places where you can find them:

FQAS
What is the life of a CR2450 battery?
If stored properly, it can last for 7-10 years, and some models are even longer.
Can CR2450 batteries be recharged?
No, CR2450 batteries are not rechargeable.
What batteries can replace CR2450?
Using the appropriate battery holder, CR2430 batteries can replace CR2450 batteries; but pay attention to the difference in capacity (CR2430: 270-290 mAh, CR2450: 600-620 mAh) and maximum pulse current.
Can I use CR2032 for CR2450? Are CR2032 and CR2450 interchangeable?
With a proper battery holder, theoretically, a CR2032 battery can be used instead of a CR2450 battery.
