Introduction to CR2032 vs CR1632


What is CR1632 Battery?


The CR1632 battery is a compact 3V lithium-manganese button cell. In actual use, for simplicity, people sometimes only retain the size information, such as 1632 battery, to refer to it. Its precise size - 16mm diameter and 3.2mm thickness - makes it an ideal power source for many small electronic devices. CR1632 batteries are widely used in various low-power electronic devices in our daily lives, including remote controls, calculators, electronic scales, etc. They play a vital role in these devices, providing stable power support for the normal operation of the devices.


What is CR2032 Battery?


The CR2032 battery is a compact 3-volt lithium coin cell battery. Similar to the relationship between the CR1632 and 1632, the battery is sometimes referred to by its size, such as 2032 battery. With a diameter of 20 mm and a thickness of 3.2 mm, this battery is ideal for space-constrained devices such as keychains, watches, remote controls, and fitness trackers. CR2032 batteries are also essential in computers, where they maintain CMOS memory and system clock settings. Known for their durability, these batteries can hold a charge for years, making them a popular choice for devices that need to be replaced infrequently, such as digital thermometers, calculators, and smart home sensors. With their versatile performance and compact size, CR2032 batteries have become a mainstay in small electronic devices.



Specifications and Dimensions


Size and Weight


Diameter and Thickness

129f25fe91d961f9f6367482dba74a23.jpg

When comparing CR2032 and CR1632 lithium battery, size plays a crucial role. The CR2032 has a diameter of 20mm and a thickness of 3.2mm. In contrast, the CR1632 measures 16mm in diameter with the same thickness of 3.2mm. This size difference may seem small, but it has a significant impact in practical applications. Due to the reduced diameter, the CR1632 battery may require more delicate handling when loading into the device to ensure that it can be firmly fixed in the battery compartment. At the same time, this also means that the CR1632 coin cell battery may not be compatible with devices designed for CR2032 coin cell battery.


Weight Comparison

Weight also varies between these two batteries. The larger diameter of the 2032 lithium battery results in a slightly heavier battery compared to the 1632 lithium battery. This weight difference can influence the choice of battery depending on the device’s design and weight sensitivity.


Voltage and Capacity


Voltage Ratings

Both CR2032 and CR1632 batteries provide a consistent voltage of 3V. This voltage is standard for many small electronic devices, ensuring reliable performance across various applications.


Capacity Differences

The significant difference between CR2032 3v battery and CR1632 3v battery is the capacity. The CR2032 offers a capacity of approximately 220mAh, allowing for longer usage before replacement. On the other hand, the CR1632 has a capacity of about 140mAh. This difference means the CR2032 button cell battery can power devices for a more extended period, making it suitable for high-drain applications.


Note: The operating temperature for the CR2032 ranges from 0℃ to 60℃, while the CR1632 operates between -20℃ and +60℃. This flexibility in temperature range might influence your choice based on environmental conditions.



Performance Characteristics


Run Time and Efficiency


Calculating Run Time

When choosing between CR2032 and CR1632, understanding run time is crucial. The CR2032 3v coin battery offers a capacity of about 225 mAh, while the CR1632 3v coin battery provides around 140 mAh. This difference means the CR2032 lithium 3v coin battery can power devices for a longer period. To calculate run time, divide the battery’s capacity by the device’s current draw. For example, if your device uses 10 mA, the CR2032 will last approximately 22.5 hours, whereas the CR1632 will last about 14 hours.

Efficiency in Various Devices

The efficiency of a device depends on the type of battery used. Specifically, CR2032 batteries are ideal for powering devices that consume more power, such as medical sensors or remote controls, due to their large capacity, which can significantly improve the operating efficiency of these devices. In contrast, the smaller capacity CR1632 3 volt battery is more suitable for providing long-lasting and stable power to low-power devices, such as watches or calculators. Therefore, choosing the right battery type for your device is key to ensure its optimal performance and long life.


Internal Resistance


Impact on Performance

Internal resistance affects how efficiently a battery delivers power. Lower resistance means better performance, especially in high-drain applications. Both CR2032 and CR1632 have similar chemistry, but the larger size of the 2032 battery often results in slightly lower internal resistance. This characteristic enhances its ability to maintain voltage under load, making it more suitable for demanding devices.


Comparison of Internal Resistance

Comparing internal resistance helps you understand performance differences. The CR2032 typically exhibits lower internal resistance than the CR1632. This difference allows the CR2032 to deliver consistent power, even in devices that require sudden bursts of energy. For applications where stable power delivery is essential, the battery CR2032 often proves to be the better choice.



CR2032 vs CR1632: Replacements


CR2032 Battery Equivalent

·CR2025: This battery has the same diameter as the CR2032 (20mm), but it is thinner (2.5mm instead of 3.2mm). If the device's battery compartment can accommodate the slightly thinner battery, CR2025 may be a viable alternative. However, note that the CR2025 typically has a lower capacity than the CR2032.

·CR2450: This battery has a larger diameter (24mm) and the same thickness as the CR2032 (3.2mm). It may not fit in devices designed for CR2032 batteries due to its larger size. However, if the device's battery compartment is larger, CR2450 could be considered, especially if higher capacity is desired.


CR1632 Battery Equivalent

·BR1632: BR1632 batteries are identical to CR1632 batteries in size and voltage, making them a perfect replacement option. However, it is important to note that different brands of batteries may vary in performance and quality, so consider the brand and manufacturer's reputation when choosing a replacement battery. 

·CR1616: Also a button cell, the CR1616 has the same voltage as the CR1632, but has slightly different dimensions (16mm diameter, 1.6mm thickness). However, in some cases, if the battery holder of the device is loose enough, the CR1616 may be able to be a replacement option. However, in general, due to the difference in thickness, the CR1616 is not a direct replacement for the CR1632.

·CR1620: Although a different model, the CR1620 battery is similar in size and voltage to the CR1632, making it a good replacement option. However, it is important to note that the battery capacity may vary between models, which may affect the battery life of the device.

·DL1632: The DL1632 battery also has the same size and voltage as the CR1632, making it a good replacement option. The DL1632 may have different capacity and discharge characteristics compared to the CR1632, but this does not usually affect its normal use in most devices.

·ECR1632: The ECR1632 is another battery model similar to the CR1632, with the same size and voltage. Therefore, it can also be used as an alternative option to the CR1632.
