What Battery is Equivalent to CR1620（CR1632 VS CR1616 ）

CR1620 description

The CR1620 coin cell battery, chemically known as a lithium manganese dioxide button cell battery, commonly referred to as a button cell, button battery, or coin cell, belongs to the CR series. It is widely used in various electronic devices such as digital watches, game consoles, computers, remote controls, electronic clocks, hearing aids, remote sensing devices, radio navigation beacons, sonar systems, search and rescue equipment, and more. 

Characteristics of this type of battery include low self-discharge, long shelf life, high single-cell voltage, high energy density, good sealing performance, stable discharge voltage, wide operating temperature range, and consistent performance. When using CR1620 batteries, it is important to avoid stacking batteries haphazardly, refrain from placing them in metal containers, store them away from damp or high-temperature environments, and keep them out of reach of children to ensure safety and optimal performance.

CR1630 features

CR1620 applications

Can CR1620, CR1632, and CR1616 batteries be used interchangeably?

CR1620, CR1632, and CR1616 batteries are all non-rechargeable lithium manganese dioxide batteries designed for single use to provide stable energy supply to various small electronic devices such as watches, calculators, and remote controls. Due to their chemical composition and design, these batteries are not rechargeable and should be properly disposed of after use to ensure safety and environmental protection.

However, although CR1620, CR1632, and CR1616 all have a diameter of 16.0mm and a voltage of 3V, their thickness and capacity differ, making them incompatible with each other. While in general, a battery compartment designed for a CR1620 may also fit a CR1616, inserting a CR1616 battery into a CR1620 slot may result in the device not functioning properly or being damaged. Similarly, a CR1620 cannot be substituted for a CR1632.

The disadvantages of mixing or replacing batteries of different specifications

1 Inappropriate size: Different specifications of the battery size is different, may not be correctly installed in the battery compartment of the device, resulting in poor contact or the device cannot work properly.

2 Voltage and capacity mismatch: Different specifications of batteries have different voltage and capacity characteristics, the use of mismatched batteries may lead to abnormal circuit work, damage, or shortened battery life.

3 Safety risks: If the battery specifications do not match, the battery may overheat, leak, or explode, which poses potential risks to the device and users.

Therefore, to ensure the normal operation of the device and protect the safety of the device and users, you are advised to select the correct battery model according to the device specifications. Do not mix or replace batteries of different specifications.
