Precautions for using CR2016 batteries


Common questions and answers about CR2016 batteries


Is CR2016 the same as CR2032?


dissimilarity. The diameter of CR2016 is 20mm and the thickness is 1.6mm; The diameter of CR2032 is also 20mm, but the thickness is 3.2mm. Therefore, although they have the same diameter, CR2032 is thicker and has a larger capacity than CR2016.

What battery is equivalent to CR2016?


CR2016 is a 3V lithium battery. If a substitute is needed, one should look for batteries of the same voltage and similar size. For example, labels such as E-CR2016 or DL2016 may indicate similar battery specifications.

Which devices use CR2016 batteries?


This type of small battery is commonly used in watches, calculators, small electronic game consoles, car key remote controls, medical equipment (such as blood glucose meters), and some portable electronic devices.

How long can CR2016 batteries last?


This depends on the specific device used and its power consumption. In low-power devices, CR2016 can operate continuously for months to years. The specific service life needs to refer to the information provided by the equipment manufacturer or the actual usage situation.

Can I replace CR2016 with CR2032?


It cannot be directly replaced because the thickness of the two is different. Forceful use may result in the device not being able to shut down properly or damaging its internal structure. In addition, due to the large capacity of CR2032, it may not be suitable for all circuits designed to use CR2016.

Can I replace the CR2016 battery with CR2025?


It cannot be directly replaced because the thickness of CR2025 is 2.5mm, which is thicker than CR2016. Similarly, doing so may result in device incompatibility or physical unsuitability.

What is the difference between CR2016 and CR2025?


Both are 3V lithium batteries with a diameter of 20mm. The main difference lies in their thickness (1.6mm for CR2016 and 2.5mm for CR2025), which means that CR2025 has a higher capacity.

What is the difference between CR2016 and CR1616 3V batteries?


Although both batteries provide 3V output, the diameter of CR2016 is 20mm and the thickness is 1.6mm; The diameter of CR1616 is 16mm and the thickness is also 1.6mm. So their volumes and shapes are completely different and cannot be interchanged.

What is the difference between CR2016 and CR2018 batteries?


The diameter of R2018 battery is also 20mm, but its thickness is 1.8mm, slightly thicker than CR2016. This makes CR2018 slightly higher in capacity than CR2016, but due to their similar size, it may be used as an emergency replacement in some cases. However, this is not recommended as it may affect equipment performance or lifespan in the long run. It is always recommended to use batteries of the specified model for the device.

summary

CR2016 battery is a high-performance, long-life small lithium battery widely used in various small electronic devices. Its high energy density, low self discharge rate, and wide operating temperature range make it an ideal choice for many applications. Through proper use and maintenance, CR2016 batteries can provide reliable and long-lasting power support.
