cr2032 battery vs cr2025 vs cr2016
The CR2032, CR2025, and CR2016 batteries are all lithium coin cell batteries, and while they share similarities, there are important differences in their specifications that can affect their performance and compatibility.
| Specification | CR2032 | CR2025 | CR2016 |
|---|---|---|---|
| CR2016 | 20 mm | 20 mm | 20 mm |
| Thickness | 3.2 mm | 2.5 mm | 1.6 mm |
| Voltage | 3V | 3V | 3V |
| Capacity | ~200–240 mAh | ~150–170 mAh | ~80–90 mAh |
| Weight | ~3 grams | ~2.5 grams | ~1.8 grams |
| Usage Life | Longer (higher mAh) | Medium (lower mAh) | Shorter (lowest mAh) |
Similarities
Voltage: All three provide a consistent 3V output, so they are often interchangeable in terms of voltage requirements.
Diameter: They all have a standard diameter of 20 mm, meaning they fit into the same-sized battery compartments.
Which One to Use?
The choice between these batteries depends on your device's requirements:
CR2032: Best for devices requiring longer battery life or higher power draw, such as LED lights, medical devices, or CMOS motherboards.
CR2025: Ideal for medium-power applications like car key fobs and calculators.
CR2016: Suited for low-power devices like small watches or basic remote controls.
CR2032, CR2025, and CR2016 batteries Can Be Interchanged?
Thickness: A thicker battery like the CR2032 may not fit in compartments designed for the thinner CR2025 or CR2016.
Capacity: Using a thinner battery (e.g., CR2025 instead of CR2032) will result in shorter battery life.
Voltage: As all three provide 3V, they won't damage devices designed for 3V power, but capacity differences could lead to faster replacement needs.
Conclusion
If your device specifies a particular battery, it is best to use the recommended size for optimal performance and fit. If you have a choice:
Choose CR2032 for longevity.
Opt for CR2025 or CR2016 if compartment size is constrained or if the device has low power demands.
Tips for Usage battery duracell cr2032
Store unused batteries in a cool, dry place to preserve shelf life.
Avoid short-circuiting the battery by keeping it away from metal objects.
Always check the device's compatibility before replacing the battery.
Common Questions
1. Are CR2032 batteries rechargeable?
No, they are primary (non-rechargeable) batteries. Using rechargeable alternatives, like LIR2032 (lithium-ion), is possible if the device supports them, but these operate at a slightly lower voltage (3.6V).
2. What are equivalent batteries?
Equivalent alternatives include:
BR2032 (same size but designed for extended high-temperature performance).
DL2032 (Duracell's version of CR2032).
KCR2032 (used by certain manufacturers).
3. How should CR2032 batteries be disposed of?
These batteries contain lithium, which is considered hazardous waste. Dispose of them at a local recycling center or battery collection point.
4.What is the difference between CR2032 and CR2025/CR2016?
Thickness: CR2032 is thicker (3.2 mm);
Capacity: CR2032 has a higher capacity (200–240 mAh);
Interchangeability: CR2032 can replace CR2025 and CR2016, but make sure the battery slot is deep enough.
5.What is the difference between CR2032 and BR2032?
CR2032: uses lithium manganese dioxide chemistry, suitable for general use.
BR2032: uses lithium polycarbonate fluoride chemistry, better suited for high temperatures or devices that require a steady current for a long time.
6. How to use and store CR2032 batteries safely?
Storage: Store in a dry, cool place, away from heat or humidity.
Avoid short circuits: Do not place batteries together with metal objects.
Keep away from children: CR2032 batteries are small and easy to swallow, and swallowing them accidentally may cause serious injury.
7.Why does the device need to have its CR2032 battery replaced?
When the device is low on power or displays the battery symbol, it may be because the CR2032 battery is exhausted. Replacing it will usually restore normal operation.
