What is CR1632 Battery?

A popular lithium coin cell battery that is small and adaptable, the CR1632 battery is utilized in a wide range of small electronic gadgets. It has dimensions of 16 mm in diameter and 3.2 mm in height. It has a nominal voltage of 3 volts and a capacity of 120-140 mAh. This type of battery is widely used in watches, medical gadgets, automobile key fobs, and compact remote controls because of its long shelf life, consistent voltage output, and high energy density in relation to its size.

The CR1632, which is made of lithium and manganese dioxide, typically lasts between two and five years, depending on usage and storage circumstances. Because these batteries contain lithium, users should manage and dispose of them appropriately even if they have many benefits for small electronics. CR1620 or CR1625 batteries could be appropriate substitutes in certain situations, depending on the demands of the particular gadget.

What is CR2032 Battery?

A widespread and adaptable lithium coin cell battery used in a wide range of electronic products is the CR2032 battery. It has dimensions of 20 x 20 x 3.2 mm and a standard voltage of 3 volts. Its usual capacity is between 210 and 240 milliampere-hours. Due to its lifespan and dependability, this battery is widely used in gadgets including motherboards, automobile key fobs, fitness trackers, calculators, and many types of remote controls.

The CR2032, which is made of lithium and manganese dioxide, has a consistent power output and a lifespan of two to five years, depending on usage habits and application. Because of its bigger size in comparison to certain other coin cell batteries, it has a higher capacity, which makes it appropriate for devices that require fewer battery changes or higher power requirements. Because of its lithium component, safe handling and disposal are crucial even if it is highly efficient and long-lasting. An industry standard for many small electronic devices, the CR2032 is widely used and readily available in both consumer and industrial applications.

CR1632 vs. CR2032: Are they interchangeable?

CR1632 and CR2032 batteries have the same voltage of 3V, but they are not compatible because of their size variances. The CR2032 has a greater diameter of 20mm with the same thickness as the CR1632, which has a diameter of 16mm and a thickness of 3.2mm. Because of this size discrepancy, a CR2032 may fit into some devices meant for a CR1632, but because of its greater size, it may cause problems including inappropriate contact or possible damage. Compatibility-wise, putting a CR2032 in a device designed to use a CR1632 could cause stress on the device's parts or prevent it from closing correctly. While some users have reported success utilizing a CR2032 instead of a CR1632 in specific situations, this is not always advised and may result in damage or malfunction. For best results and to minimize dangers, it is therefore usually advised to use the battery type that the manufacturer specifies. Using the appropriate battery type is the recommended practice, as CR2032s are not interchangeable, even though they might function in some situations.
