Frequently Asked Questions
Can I use a CR1220 instead of CR1216?
While CR1220 and CR1216 batteries share the same 12.5mm diameter, the CR1220 is thicker at 2.0mm compared to the CR1216's 1.6mm. This 0.4mm difference can cause fit issues in devices designed specifically for CR1216 batteries. The CR1220 also has a higher capacity (around 35-40 mAh vs. 25-30 mAh for CR1216).
In some devices with flexible battery compartments, a CR1220 might work as a temporary replacement, but it could cause pressure on components or prevent proper closure of the battery compartment. For optimal performance and to avoid potential damage, it's best to use the exact battery size specified by your device manufacturer.
Are CR1216 batteries interchangeable with CR2016?
No, CR1216 and CR2016 batteries are not interchangeable. While both have the same height (1.6mm), they differ significantly in diameter. The CR1216 has a 12.5mm diameter, while the CR2016 has a 20mm diameter. This substantial size difference makes them incompatible with each other's battery compartments.
Additionally, the CR2016 has a much higher capacity (around 90 mAh compared to the CR1216's 25-30 mAh), making it suitable for higher-drain devices. Always use the battery size specified by your device manufacturer to ensure proper fit and performance.
How long do CR1216 batteries typically last?
The lifespan of a CR1216 battery depends on the device and usage patterns. In low-drain devices like watches, a CR1216 can last 1-3 years. In devices with higher power requirements or frequent use (like small remote controls or medical devices), the battery may last 6-18 months.
Factors affecting battery life include:
- Device power requirements
- Frequency of use
- Operating temperature (extreme temperatures reduce battery life)
- Battery quality (premium brands often last longer)
- Storage conditions before installation
Is CR1216 the same as BR1216?
While physically identical in size (12.5mm × 1.6mm), CR1216 and BR1216 batteries use different chemical compositions and have slightly different electrical characteristics:
- CR1216: Uses lithium manganese dioxide chemistry with a 3.0V nominal voltage
- BR1216: Uses lithium carbon monofluoride chemistry with a 2.8V nominal voltage
BR1216 batteries offer a more consistent discharge curve and extremely low self-discharge rate (less than 1% per year), making them ideal for long-term applications with minimal power requirements. However, they provide lower current output, making them unsuitable for devices with alarms, LED lights, or other features requiring momentary higher power.
How should I store unused CR1216 batteries?
To maximize the shelf life of unused CR1216 batteries:
- Store in a cool, dry place at room temperature (10-25°C or 50-77°F)
- Avoid extreme temperatures, which can degrade battery performance
- Keep in original packaging to prevent accidental short circuits
- Store away from metal objects that could connect the positive and negative terminals
- Keep out of reach of children and pets to prevent accidental ingestion
Properly stored, CR1216 batteries can maintain their charge for up to 10 years with a self-discharge rate of approximately 1% per year.
Conclusion
Finding the right CR1216 battery equivalent doesn't have to be complicated. By understanding the specifications, knowing the compatible alternatives, and considering your device's specific requirements, you can select the perfect replacement that ensures optimal performance and longevity.
Whether you choose a direct equivalent like DL1216 or ECR1216, or opt for a specialized alternative like BR1216 for long-term applications, the key is matching the battery to your device's needs. Remember to consider factors like voltage requirements, expected lifespan, and operating conditions when making your selection.
For most applications, major brand equivalents from Duracell, Energizer, Panasonic, or Maxell will provide reliable performance. When in doubt, consult your device's manual or contact the manufacturer for specific recommendations.
