Just like other batteries in the CR series, CR2025 and CR2016 are button batteries that seem very similar in many respects. By comparing the , we’ll see if the two are interchangeable, and what their differences are.
Button batteries are used in many small portable electronic devices. A few examples are:
- Calculators
- Watches
- Remote controls
- Car key fobs
- Thermometers
- Hearing aids
- Tea light candles
The CR2025 and CR2016 are both small single batteries with a squat cylinder shape.
Here we will compare the main specs, , , chemistry, and other features of CR2025 and CR2016 batteries. These two button cells are very similar. For instance they have the same of 20 mm, so they can fit in the same . Nevertheless, some differences exist between the two.
First here’s a concise table comparing the two batteries. After that we’ll explain how each feature in the table affects the batteries.
CR2025 vs CR2016 Batteries Comparison
| CR2025 | CR2016 | |
| Capacity | 165 mAh | 90 mAh |
| Voltage | 3 V | 3 V |
| Thickness | 2.5 mm | 1.6 mm |
| Rechargeable | Not rechargeable | Not rechargeable |
mAh is (one-thousandth of an ampere-hour)
Capacity
The capacity of a button or indicates the number of charges the can hold.
The higher the capacity of the button battery, the longer the battery will last. The capacity of the battery is dependent on the amount of active material in the button cell.
CR2025
The CR2025 has a capacity of 165 mAh. This figure is a measure of electric power over time. Most portable electronic devices that use this type of battery require very little electrical power to work.
So assuming you’re using this battery on a device that requires 5mA, this battery will last for over 33 hours, that’s over one and a half days.
CR2016
The CR2016 has a capacity of 90 . When you make use of this on a that requires 5 mAh, the will last for 18 hours, so less than a day.

Voltage
The voltage of a battery simply means how much potential is in the battery. But don’t confuse the voltage of a button battery to mean the measure of energy.
CR2025
The CR2025 battery has a potential of 3 V.
CR2016
The CR2016 battery has a potential of 3 V.
Thickness
What differentiates most button batteries is their or .
For a typical CR series , you can get the of the from the last two digits of the name in a tenth of a millimeter.
CR2025

Equivalents
Depending on various factors, the CR2025 and CR2016 button batteries can be replaced with other types of batteries. Those factors include button chemistry, voltage, and dimensions (thickness and diameter). Following are the equivalents of CR2025 and CR2016 batteries by different firms.
CR2025
CR2016 and CR2032 batteries are interchangeable and can replace a as long as they fit in your . Otherwise, all three are 20 mm thick and have the same . The only difference is , which differs x2 between the and CR2016 (3.2 mm and 1.6 mm), while both are more likely to be suitable equivalents to CR2025.
The direct equivalents to CR2025 button batteries by other brands are DL2025 (Duracell), ECR2025 (Energizer), CR2025 (Kodak, Maxell, Rayovac, Sony).
CR2016
Additionally to the above information, equivalents of CR2016 are DL2016 (Duracell), ECR2106 (Energizer), CR2016 (Kodak, Maxell, Rayovac, Sony).

Conclusion
Both batteries have the same and are 3V, so in theory, they are interchangeable.
However, they have different thicknesses. The CR2016 is 1.6 mm thick and the CR2025 is 2.5 mm thick.
The increased thickness of the CR2025 would prevent it from seating properly and therefore would not be a suitable replacement.
