Comparison Between CR1216 and Similar Batteries
While several batteries may have similar dimensions or voltage to the CR1216, they're not always interchangeable. Understanding the differences between these batteries can help you make the right choice for your device.
CR1216 vs CR1220
CR1220 and CR1216 batteries share the same diameter (12.5mm) but differ in height and capacity:
- CR1216: 1.6mm height, ~25mAh capacity
- CR1220: 2.0mm height, ~35-40mAh capacity
The 0.4mm height difference can cause fit issues in devices designed specifically for CR1216 batteries. While CR1220 offers higher capacity, it may not physically fit in all CR1216 applications.
CR1216 vs CR1225
The CR1225 is significantly thicker than the CR1216:
- CR1216: 1.6mm height, ~25mAh capacity
- CR1225: 2.5mm height, ~50mAh capacity
With nearly double the capacity, CR1225 batteries are better suited for higher-power applications but are not interchangeable with CR1216 in most devices due to the significant size difference.
CR1216 vs CR2016
| Specification | CR1216 | CR2016 |
| Nominal Capacity | 25 mAh | 90 mAh |
| Nominal Voltage | 3V | 3V |
| Weight | 0.7g | 1.6g |
| Diameter | 12.5mm | 20.0mm |
| Height | 1.6mm | 1.6mm |
| Maximum Pulse Current | 5 mA | 15 mA |
While CR2016 has the same height as CR1216, its diameter is significantly larger (20mm vs 12.5mm), making these batteries not interchangeable.

Safety Tips for Handling and Replacing Button Cells
Important Safety Warning
Button cell batteries can be extremely dangerous if swallowed, especially by children. They can cause severe internal burns in as little as 2 hours and can be fatal. Keep all button batteries out of reach of children and seek immediate medical attention if ingestion is suspected.
Safe Handling Guidelines
- Store unused batteries in their original packaging, away from children and pets
- Never mix old and new batteries or different battery types
- Use plastic tweezers rather than metal tools when handling batteries to avoid short circuits
- Wash hands after handling batteries, as they contain chemicals
- Ensure the battery compartment of devices is securely closed after replacement
- Check that the positive (+) and negative (-) terminals are correctly aligned when installing
Proper Disposal
Button cell batteries contain materials that can harm the environment if not disposed of properly:
- Never dispose of batteries in regular household trash
- Use designated battery recycling collection points (often found in electronics stores, supermarkets, or community recycling centers)
- Place clear tape over both sides of used button batteries before recycling to prevent short circuits
- Check local regulations, as battery disposal requirements vary by location
Battery Replacement Tips
- Use proper tools designed for opening small battery compartments to avoid damage
- Take a photo of the battery orientation before removal to ensure correct installation of the replacement
- Clean battery contacts gently with a dry cloth if they show signs of corrosion
- Consider having a professional replace batteries in valuable watches or medical devices
Frequently Asked Questions
What is the shelf life of a CR1216 battery?
CR1216 batteries typically have a shelf life of up to 10 years when stored properly at room temperature (10°C-25°C). The self-discharge rate is approximately 1% per year, meaning they retain most of their capacity even after years of storage. Always check the expiration date when purchasing.
How do I properly recycle 1216 batteries?
Button cell batteries should be recycled through designated battery collection programs. Many electronics stores, home improvement stores, and community recycling centers accept button batteries. Before recycling, place clear tape over both sides of the battery to prevent short circuits. Never dispose of these batteries in regular household trash as they contain materials that can harm the environment.
Is a CR1216 battery the same as a 1216 battery?
Yes, CR1216 is the most common designation for a 1216 battery. The "CR" prefix indicates it's a lithium manganese dioxide battery with 3.0V output. When searching for a 1216 battery equivalent, you'll most commonly find it listed as CR1216, though some manufacturers may use alternative prefixes like BR, DL, or ECR followed by 1216.
Can I use a CR1220 instead of a CR1216?
While CR1220 and CR1216 batteries have the same diameter (12.5mm) and voltage (3.0V), the CR1220 is thicker (2.0mm vs 1.6mm). This means a CR1220 may not fit in devices designed specifically for CR1216 batteries. If the battery compartment has extra space, a CR1220 might work and would provide longer life due to its higher capacity, but it's generally recommended to use the exact battery type specified for your device.
How long does a CR1216 battery typically last in a device?
The lifespan of a CR1216 battery depends greatly on the device and its power consumption. In low-drain devices like watches, a CR1216 can last 2-5 years. In devices with higher power requirements or frequent use (like some remote controls or medical devices), the battery may last 6 months to 2 years. Temperature, usage patterns, and device efficiency all affect battery life.
Are generic 1216 battery equivalents as good as name brands?
Quality can vary significantly among generic 1216 battery equivalents. Name brands like Energizer, Duracell, and Panasonic typically offer more consistent performance, better quality control, and longer shelf life. However, some reputable generic brands can provide good performance at a lower cost. For critical applications like medical devices, name brands are generally recommended. For less critical uses, quality generic batteries can offer good value.
What's the difference between CR1216 and BR1216 batteries?
While both are lithium-based coin cell batteries with the same dimensions, BR1216 batteries use lithium carbon monofluoride chemistry and have a slightly lower voltage (2.8V vs 3.0V) than CR1216 batteries. BR1216 batteries typically have a lower self-discharge rate and better performance at higher temperatures but provide lower current output. They're less common today as CR1216 technology has improved to offer similar self-discharge rates with better performance in most applications.
Conclusion
Finding the right 1216 battery equivalent doesn't have to be complicated. Whether you choose a CR1216, BR1216, DL1216, or another compatible option, understanding the specifications and requirements of your device will help you make the best choice. Remember to consider factors like voltage, capacity, brand reliability, and price when selecting a replacement.
For most applications, standard CR1216 batteries from reputable manufacturers will provide excellent performance and reliability. Always handle button cell batteries safely, store them properly, and dispose of used batteries responsibly through appropriate recycling channels.
