Understanding Battery Sizes: 2016 vs. 2025

The numbers "2016" and "2025" refer to the size of button cell batteries. While they might seem similar at first glance, key differences exist that make direct interchangeability impossible in most cases. These differences impact both physical fit and electrical performance.

Physical Dimensions

2016 Battery: Diameter of 20 mm, height of 1.6 mm.
2025 Battery: Diameter of 20 mm, height of 2.5 mm.

Notice the crucial difference: the height. A 2016 battery is significantly shorter than a 2025 battery. Trying to force a 2025 into a device designed for a 2016 will likely damage the device's battery compartment. Conversely, a 2016 battery will likely be too short to make proper contact in a device expecting a 2025.

Voltage

Both 2016 and 2025 batteries typically operate at a nominal voltage of 3 volts. This seemingly identical aspect might tempt you to consider them interchangeable. However, even with the same voltage, the physical differences can lead to malfunction.

Why Interchangeability is Usually a Bad Idea

Attempting to use a 2025 battery in a device designed for a 2016 will likely result in one or more of the following issues:

Poor Contact: The taller 2025 battery might not make proper electrical contact with the device's terminals, leading to intermittent power or complete failure.
Physical Damage: The battery may bulge or even rupture under pressure, potentially damaging the device's internal components. This can also pose a fire or explosion risk.
Internal Short Circuit: If the taller battery protrudes into the device, it could create a short circuit, leading to immediate and potentially dangerous failure.

Using a 2016 battery where a 2025 is expected will typically lead to:

Non-Function: The battery simply won't power the device. It lacks the necessary height for proper contact.

Finding the Right Replacement

Always consult your device's manual or specifications to determine the correct battery type. If you're unsure, contacting the manufacturer is the safest option. Never guess! Using the incorrect battery can severely damage your device.

Safety Precautions When Handling Batteries

Dispose of batteries properly: Do not throw batteries in the trash. Use designated battery recycling programs.
Avoid short-circuiting: Never touch the positive and negative terminals simultaneously.
Handle with care: Avoid dropping or damaging batteries.

Conclusion

While both 2016 and 2025 batteries share a similar diameter and voltage, their height difference makes them incompatible. Attempting to use one in place of the other is strongly discouraged due to the risk of damage and potential safety hazards. Always choose the correct battery for your device. Prioritizing safety and checking specifications prevents costly errors.
