CR2016 vs CR2032: Replacement

 

CR2016 Battery Equivalents

 

CR2016 batteries can be replaced with a variety of equivalent models that are similar to the original battery in size, voltage, and performance. Here are some common equivalent replacement models:

Model Description
BR2016 It also has the same size and voltage as CR2016 and can be used interchangeably.
ECR2016 This is also an equivalent replacement model of CR2016 and is suitable for devices that require CR2016 batteries.
DL2016 It has the same size and voltage as CR2016 and is one of the common equivalent replacement models.
SBT11 In some cases, SBT11 can also be used as a replacement model for CR2016.

In addition, although CR2032 and CR2025 are different from CR2016 in size, since they both belong to the lithium manganese button battery series, they can sometimes be used as a replacement for CR2016 under certain conditions (such as after mechanical adjustment), but it should be noted that their capacity and thickness may be different, which may affect the performance and life of the device.

 

CR2032 Battery Equivalents

 

CR2032 batteries also have a variety of equivalent replacement models that are similar in size, voltage, and performance to the original battery. Here are some common equivalent replacement models:

Model Description
CR2450 Although the CR2450 is different in size from the CR2032, it can also be used as an alternative in certain specific applications (such as devices that require higher capacity). However, this requires the device to have enough space to accommodate the larger battery and to ensure that the electrical connection between the battery and the device is good.
CR2025 Although the thickness of the CR2025 is thinner than the CR2032, they share the same voltage and diameter. In some cases, if the device does not have strict requirements on the thickness of the battery, the CR2025 can be used as an alternative to the CR2032. However, it should be noted that due to the smaller capacity of the CR2025, its service life may be relatively shorter.

It should be noted that although the above models can be used interchangeably in some cases, in order to ensure the best performance and life of the device, it is recommended to always select the appropriate battery model as recommended by the device manufacturer. In addition, when replacing the battery, always follow the device's instructions and safety guidelines to ensure correct operation.

 

In general, there are many equivalent replacement models for CR2016 and CR2032 batteries, and the selection needs to be matched according to the specific needs of the device and the specifications of the battery. At the same time, it is also necessary to pay attention to the performance differences and compatibility issues between different models of batteries.

Fitting Issues

 

Potential Issues with CR2032 in CR2016 Devices

  • The CR2032 battery presents challenges when used in devices designed for CR2016. The primary issue involves the thickness difference. CR2032 measures 3.2 mm, while CR2016 is only 1.6 mm thick. This discrepancy often leads to fitting problems. Devices with battery compartments tailored for CR2016 cannot accommodate the thicker CR2032. Attempting to fit a CR2032 into a CR2016 slot may damage the device or the battery. Users must ensure compatibility before substitution.

 

Considerations for Interchangeability

  • Interchangeability between CR2016 and CR2032 batteries requires careful consideration. The capacity difference plays a significant role. CR2032 offers a higher capacity, impacting device performance and operation. Devices designed for CR2016 may not handle the increased power output from CR2032 efficiently. The voltage remains consistent at 3V for both batteries. However, the capacity and thickness variations necessitate caution. Users should consult device specifications to determine compatibility. Using designated battery types ensures optimal performance and safety.

 

 

Understanding the differences between CR2016 and CR2032 batteries helps you choose the right power source for your devices. CR2016 coin cell offers a compact design with lower capacity, suitable for small electronics. CR2032 coin cell provides higher capacity, ideal for devices needing more power. Both batteries operate at 3V, but their varying capacities require careful consideration. For optimal performance, match battery specifications to device requirements. Consider the space available and power needs when selecting a battery. Making informed choices enhances device longevity and reliability.

 

 

 

Frequently Asked Questions

Will a CR2032 Work for CR2016?

If your devices using single 2016 battery, a thicker 2032 usually will not fit into the 2016 slot. If your devices using two 2016 battery stacked together, replacing with one 2032 might seems to work in dimension, however the voltage is not right.

Are CR2016 and CR2032 Interchangeable?

The thicker CR2032 battery will not fit into the CR2016 battery compartment in most devices that use a single CR2016 cell.

Can a CR2016 Replace a CR2032?

While the CR2016 and CR2032 batteries have the same diameter and may deliver the same amount of volts, they are not interchangeable due to their different thicknesses.

How Long do CR2032 Batteries Last?

A CR2032 battery in a car key fob may last up to 4-5 years before needing replacement as the use of the battery is very intermittent.

Can I use CR2032 instead of CR2016 in key fob?

While both CR2032 and CR2016 batteries deliver the same 3 volts, their dimensions differ. The CR2032 is notably thicker, which could pose a problem in gadgets specifically designed for the slimmer CR2016, like car key fobs. 

Can I use a CR2025 in place of a CR2016?

Generally, you can substitute CR2025 for CR2016 if the battery compartment can accommodate the thicker CR2025. However, it's always advisable to use the battery recommended by the device manufacturer.

What are the differences between CR2016 and CR2032?

Differences between CR2016 and CR2032 button batteries go beyond just their names. Basically, the numbers in their names show their size -- both are 20 mm wide, but the key difference is how thick they are. CR2016 is slim at 1.6 mm, while CR2032 is thicker at 3.2 mm.

When should I replace my CR2032 battery?

A CR2032 battery in a car key fob may last up to 4-5 years before needing replacement as the use of the battery is very intermittent. A more active device such as the new Apple Air Tag which allows constant tracking of objects will only last about a year.

Can I replace a CR1616 battery with a CR2016?

It would appear the CR1616 is 16mm diameter and 1.6mm thick. While the CR2016 is 20mm in diameter and 1.6mm thick. So you definitely can't use CR2016 in place of CR1616 as its just too wide. Same applies to using CR2032 in place of CR2016.

Are CR2032 and CR2025 Batteries Interchangeable?

For as long as either fits in the battery compartment, the CR2025 and CR2032 may be used interchangeably with minimal effect although the CR2032 would probably last slightly longer simply because it has a higher capacity (mAh).
