All the CMOS batteries are quite similar with very few differences. Notably, 2025 and 2032 CMOS batteries are lithium cell batteries containing chromium. However, in the 2025 vs 2032 CMOS battery comparison, the main discrepancies are in their depth, weight, and capacity.
These batteries are mainly used mostly in electric devices, motherboards. Also, they can be used in toys, cars, or in some other applications. Both of the batteries have similarities and dissimilarities that you will learn from this section.

Shape
Both of the CR2032 and CR2025 CMOS batteries are button battery that looks like coins. For this reason, they require only a bit of space in your device. The ‘R’ of the battery name stands for its round shape.
Diameter
The duo of CR2025 and CR2032 batteries have the same with or diameter of 20mm. Because of this factor, they are interchangeable. The first two numbers of the battery name ‘20’ stand for the diameter.
Depth
Depth is the only visual difference for these 2025 and 2032 batteries. The CR2025 battery has 2.5mm and the CR2032 battery has 3.2mm. The last two numbers of the battery names such as ‘25’ and ‘32’ stand for their respective depth.
Operating Temperature
Each of the 2025 and 2032 CMOS batteries works properly under the temperature range of 0°C to 60°C. But the range varies from battery to battery of different brands. If the operating temperature goes beyond the standard range, the battery will lose its capacity and the device will start malfunctioning or not work at all.
Weight
The weight of the CMOS batteries also varies with their depth. For the CR2025, the weight is 2.3gram and for CR2032, the weight is 3.1gram.
Voltage
The nominal voltage for both the 2032 and 2025 CMOS batteries is the same, which is 3V. Because of this shared feature, both of the batteries can act as a replacement for another one.
Capacity
Capacity is one of the main differences between the CR2025 and CR2032 batteries. The 2032 CMOS battery offers more capacity which is 235 mAh. On the other hand, the 2025 CMOS battery capacity is only 170 mAh.
Rechargeability
None of the 2032 and 2025 CMOS batteries are separately rechargeable. They only get charged via laptop while it is plugged in.
Disposable
2025 and 2032 CMOS batteries are disposable. You can easily remove them and toss them away. It’s better to recycle them or dispose of them via an authorized facility since they contain chemicals.
Can a 2032 Battery Replace a 2025 Battery
In the case of 2025 vs 2032 CMOS battery, the 2032 battery is the superior one. Because CR2032 does not only have a higher capacity but also lasts longer than the other battery. You better keep some spare CMOS batteries for any emergency.
