Similarities:
Here are the key similarities and differences between CR1216 batteries and their equivalents:
Similarities:
Physical dimensions: All CR1216 equivalent batteries have the same diameter (12mm) and height (1.6mm) as the CR1216. This allows them to fit in the same battery compartments and be used interchangeably.
Voltage: CR1216 and its equivalents all have a nominal voltage of 3V. They provide the same electrical power to the devices they are used in.
Chemistry: These batteries use the same lithium manganese dioxide (LiMnO2) chemistry. They have similar performance characteristics and shelf life.
Applications: CR1216 and equivalent batteries are commonly used in small electronic devices like watches, calculators, key fobs, medical devices, etc.
Differences:
Naming convention: While functionally the same, the equivalent batteries have different names/part numbers based on the manufacturer or reseller. For example, Duracell uses DL1216, Energizer uses ECR1216, Panasonic uses CR1216 or BR1216, etc.
Capacity: Although very similar, the exact mAh capacity can vary slightly between manufacturers. CR1216 batteries typically range from 25-30 mAh. But this minor difference does not significantly impact performance in most applications.
Price & availability: Depending on the brand and retailer, prices may vary slightly between CR1216 and equivalents. Some brands or part numbers may be more readily available in certain regions.
Applications
CR1216 batteries are commonly used in small electronic devices, such as:
CR1216 vs CR1220 Battery
![CR1216 vs CR1220 Battery CR1216 vs CR1220 Battery](/uploadimg/CR1216 vs CR1220.jpg)
Here are the key differences between CR1216 and CR1220 coin cell batteries:
CR1216 vs CR1220: Physical Dimensions
The main difference is in the height/thickness of the batteries:
CR1216:
Diameter: 12 mm
Height: 1.6 mm
CR1220:
Diameter: 12 mm
Height: 2.0 mm
So the CR1220 is 0.4 mm thicker than the CR1216. The diameter is the same at 12 mm.
CR1216 vs CR1220: Capacity
Due to the increased thickness, the CR1220 has a higher capacity:
So the CR1220 can provide about 25-30% more capacity compared to CR1216.
CR1216 vs CR1220: Voltage
Both batteries have the same nominal voltage of 3V. They use the same lithium manganese dioxide (LiMnO2) chemistry.
It is generally not advisable to use a CR1216 in place of a CR1220, as the lower capacity may lead to shorter battery life. Always check the device manual for the specific battery requirements.
CR1216 vs CR1220: Applications
CR1216 and CR1220 batteries are used in similar small electronic devices like watches, calculators, car key fobs, medical devices, etc. The choice between them depends on the device's size constraints and power requirements.
In summary, the key difference is that CR1220 batteries are 0.4 mm thicker and have about 25-30% more capacity than CR1216 batteries, while keeping the same diameter and voltage. This makes the CR1220 preferable for devices that can accommodate the extra thickness and benefit from longer battery life.
