CR2025 and CR2032 are two common button battery models that are very similar in size, action, and use, and many people are somewhat confused when buying, not knowing the difference between the two. Today, let's explore the differences between the two types of battery buttons.
What is CR2032
The CR2032 battery is also 20 mm in diameter, but 3.2 mm thick. Also a lithium manganese oxide battery, the CR2032 battery has a high capacity (usually about 210mAh). It is often used in computer motherboards, car keys, electronic scales, heart rate monitors and other devices that require higher capacity.
What is CR2025
The CR2025 battery has a diameter of 20 mm and a thickness of 2.5 mm. It is a lithium manganese oxide battery and has a lower capacity (usually about 150mAh). CR2025 batteries are widely used in small electronic devices such as calculators, remote controls, watches, and small electronic game consoles.

Conclusion:
1 The CR2032 has a larger capacity than the CR2025 and is able to provide more power, which is suitable for devices that require high power consumption.
2 CR2032 and CR2025 batteries are both rated at 3V, which means they can both provide a stable and reliable current. They can provide a reliable voltage even when the battery is depleted, making them popular in devices that require less than 20 mah of current, such as small calculators.
3 CR2032 has a higher energy density and a longer lifetime.
So when buying, how should we choose?
First of all, it depends on your use scenario, if you need a battery to provide higher power, then CR2032 is a good choice, secondly, we also have to consider the price of the battery, due to the high power density of CR2032, so its price will be higher than CR2025, if you have a price budget requirements. Then CR2025 is a more affordable option.

Are CR2025 and CR2032 interchangeable?
Although the two have the same diameter, belong to the buckle lithium manganese battery, and the voltage is 3v, but due to the difference in thickness and capacity, the CR2025 battery can be installed on the device using CR2032, but CR2032 may not be installed in the device using CR2025. In theory, CR2025 can be used instead of CR2032 (as long as the battery holder where the battery is placed can fix CR2025), but CR2032 cannot replace CR2025. However, in order to prevent problems such as poor contact and insufficient power supply, it is recommended not to put the two batteries together for mutual use.
Choice between different CR model button batteries
When choosing different button battery models, we need to pay attention to factors such as voltage, size, and capacity. When you are wondering whether two types of button battery can be common, such as CR2025 and CR2032, you need to pay attention to whether the size of the product design can meet the specifications of CR2032 and CR2025. Larger batteries can hold higher capacity, and the higher the capacity, the longer the use time. If the design space of the product is large enough that the diameter and thickness can accommodate both models, then they can theoretically be universal. However, if the capacity of the two models is not the same, it is not ruled out that there will be problems such as poor contact and inability to supply power.
